==There is a story behind every bike I own 12/2024==

Warning, 17mile story ahead.

Long long ago when I was building the 888LTD for Wally, there was a need for a set of 5spoke Marchesini wheels which many know are impossible to find for the 851/888 platform. My solution at the time was to find an S4 and buy it for the wheels which we did. I found a decent bike in upstate NY and drove out and paid cash for it (well, wally paid cash for it). The bike was your base model Monster S4, all stock, red, a good bike.

After stealing the wheels I was left wondering what fun could be had with a monster when left to my own devices and I think we found the way. I sourced a set of Sport classic wire wheels and a handful of other bits and started to goto work on the bike. The first thing to do was to paint the red away which I did with BMW's laguna sec blue (the same color as my race bikes at the time), then was the wheel swap, slipper clutch, power commander, clip ons and a saw to the exhaust.

The result was awesome: A loud, fun little run around with a decent amount of power. One of the biggest challanges was getting the gold line brakes to clear the spokes on the wire wheels (remember Ducati's solution to this was to use smaller, less brakes which I was having none of). My solution was to mill down the calipers until they cleared, the risk was blowing into the backs of the calipers and making a mess of my mill (this never happened luckly!)

The bike was totally stock when purchased, here it is in the back of the truck on its way to my shop in 2007

[[File:SSPX0048.jpg|link=File:SSPX0048.jpg|center|700px]]

I quickly took the bike apart, installed clip-ons, chopped the pipes, added wire wheels and a few other things

[[File:Monster3.jpg|link=File:Monster3.jpg|center|700px]]

I then painted the bike BMW Laguna Seca Blue which was my favorite. Here was the bike in 2008 when it was in my possession still

Here you can see my mill work on the calipers to get them to clear the spokes. I know, Im nuts!

[[File:StolenS4-Caliper.jpg|link=File:StolenS4-Caliper.jpg|center|700px]]

At the time I lived with a very close friend who I trusted and who didn't have a bike. I offered the bike to him to use and was foolish enough to give him the title and let him register the bike, which he did. A time later he and I had a big falling out where I offered for him to keep the bike, only to be told "Fuck you and your bike, I don't want it". A few weeks later he moved out and the bike left with him which surprised me, after all "fuck me and my bike" right? Well, I tried for 6 or 7 years to get the bike back and was repeatedly told I could buy the bike back which I refused to do.

Time went on and the guy sold or gave the bike to a fellow, who sold or gave the bike to another fellow. Rumors of the bike being for sale floated around and I even tossed a number out there for the bike but it was far too high for what I knew the bike was worth, so I passed. My friend Rocket got a call from the guy who had the bike and was offered the thing at more than half what I was offered it (this happens to me a lot) and Rocket called me to get the bike. I was so pissed about the number that I told him to shove it (so that he would tell the guy who had it to shove it) and that was the end of it. So I thought.

==So there I was, a week before Christmas 12/2024==

Working around the house, doing shit. Im talking to my wife and I hear this noise, a noise that is hard not to recognize, and my wife's smile which is a "I got you" smile. I start laughing and walk out to find Rocket in the driveway, sitting on the S4 in 20degree wheather freezing his ass off but cracking up! She had bought me the bike! Her words were: "Now the collection is all back together". My wife is the shit but little did she know that this move was going to cost me a ton of cash!

Here she is when it was returned to me. The Black livery is questionable, the clip-ons have been removed and a lot of other bits had been changed but overall she was still the bike I had last seen her as.

[[File:Stolen-S4-first-delivered.jpeg|link=File:Stolen-S4-first-delivered.jpeg|center|700px]]

==The buying spree begins 1/2025==

Because I know this bike so well and also know the platform in and out, before even riding this bike I did two things:
*Registered it
*Sourced most of the hard to find parts before taking it apart

The first challenge was a known one. The RI title I had last seen for this bike had a typo where an I was written as a 1 (common in RI long ago). The previous fellow decided to register it in Vermont and not deal with this. I went to the DMV, played dumb and had them check pictures of the stampings and fix the incorrect VIN.

As for sourcing parts, I went a bit haywire (shocker right). I decided go big or don't do it:
*Ohlins SBK fork with Radial bottoms (1198)
*Brembo 1198 radial calipers
*Brembo Radial master clutch and slave
*Speedymoto Monster to SBK triples
*Helibar clipons with a slight rise
*Termi spaghetti system with high mount Ti cans (Japan sourced, I have never seen these in the States, ever)
*Termi Monster 1100S cans, to be modded to fit the spaghetti systems while retaining the two up riding ability.
*Ohlins rear shock from an ST4s

The bummer about all this is the loss of the wire wheels. One of my favorite parts of this build is a monster with SC wheels but if I want radial brakes, the wheels must go, so they go because I like my brakes more than I like spoked wheels!

==Teardown and playing 10/2025==
With this bike, I didn't need to get her running, she is a runner. Right into the teardown and with it starts the mockup.

Here she is up on the lift, still basically a bike

[[File:Stolen4-teardown-1.jpeg|link=File:Stolen4-teardown-1.jpeg|center|700px]]

A little more extreme breakdown:

[[File:Stolen4-teardown-2.jpeg|link=File:Stolen4-teardown-2.jpeg|center|700px]]

This teardown will be jumping between teardown and mockup so unlike many of my other builds, this bike will look a lot more together throughout its evolution.

==Frontend build and mockup 10/2025==
For this bike I thought the 1098 / 1199 Ohlins with radials would look cool (and ride fucking awesome), the old FG43 bottoms are rad and all but really stand for the 90s and early 2000s. With the monster and all its swooping curves, the interegal radials will have a good look with the rest of the bike (I hope), additionally the final OG monster (S4RS) had radial bottoms but where a non SBK fork.

Here you can see them being serviced at Superbike services44 in New Hampshire. It always cracks me up to see the cost savings for ohlins when they only plate in gold the bits you see and not the others

[[File:Stolen4-tubes.jpeg|link=File:Stolen4-tubes.jpeg|center|700px]]

How many licks does it take to get to the center of a tootsie pop? The same can be said as to how many parts make up a front fork.

[[File:Stolen4-internals.jpeg|link=File:Stolen4-internals.jpeg|center|700px]]

When it came time to figure out the front end on this bike I was laser focused on an S4RS full front end but they were hard to find and not as good. I then remembered I had this fork in a pile but that it would require unique triples, lucky for me speedy moto dealt with this long ago and made a tripe for it. Im not a huge fan of the black anodizing but it is all I could get! Powder coating will resolve the black issue.

[[File:Stolen4-triples.jpeg|link=File:Stolen4-triples.jpeg|center|700px]]

For clipons, I went with a set of Helibars that came to me in a bulk buy. They are NOS and give me almost an inch up which should be good for 2up riding which this bike will be used for. I am also toying with wire wheels or 999 wheels, here you can see the 999 option.

[[File:Stolen4-front-test-1.jpeg|link=SFile:tolen4-front-test-1.jpeg|center|700px]]

It is always funny to see a bike with no headlight and no fairing, everything looks wrong.

Next up I have to figure out the wheel situation. Running a 999 rear in the ST / S4 swingarm is going to be challenging and at the the same time running a wire wheel in the 1198 fork has brake clearance challenges. More to come there in the coming weeks. My pref is wire but they are heavier. I don't know..

==Driveline Mockup 10/2025==
My plan was to run 749/999 wheels on this bike to allow for radial from calipers but much to my delight, the SC wire wheel spokes JUST clear the calipers, I will be milling them a tad just to allow for some more room.

Sticking with the wire wheels on this build makes me very happy, for some reason I have always loved the look of the SC aluminum hub / rim wheels along with road tires (which are not what are on these wheels right now). I have another set of wheels that are un-used that will be getting a set of road tires mounted in the coming weeks.

Monsters look funny without the big ass rearsets installed as you can see. I was thinking about doing away with them for the aesthetic but I want this bike to be good for two up riding so they will be sticking around.

[[File:Stolen4-driveline-mock-1.jpeg|link=File:Stolen4-driveline-mock-1.jpeg|center|700px]]

The ST4S rear shock mounted well and the rez plumbing clears the frame the way I had hoped. Here you see the rebound adjuster
[[File:Stolen4-driveline-mock-2.jpeg|link=File:Stolen4-driveline-mock-2.jpeg|center|700px]]

On the other side you see the compression adjust / rez with the line fitting well in the frame.
[[File:Stolen4-driveline-mock-3.jpeg|link=File:Stolen4-driveline-mock-3.jpeg|center|700px]]

Im testing the OG cast iron floating rotors on one side to see how the clearance is, which is perfect. For some reason I love these Tron looking rotors and am happy to have a bike I can run them on (6 bolt with the correct offset), all my other bikes are so modified I had to go other directions.
[[File:Stolen4-driveline-mock-4.jpeg|link=File:Stolen4-driveline-mock-4.jpeg|center|700px]]
==Body work planning 11/2025==
Talking about bodywork on a monster is the wrong way to put it but I had to come up with something. Those that know the monster know it's entire market is based on the lack of bodywork but here we will talk about the three major parts:
Tank: Monster S4RS
Front fender: Monster 1100S
Seat cowl: Monster S2R

To start I always like to switch it up with the front fenders on these builds so after poking around, I settled on a very modern looking 1100S monster fender, My fingers are crossed here. The Tank is from an S4RS so it is plastic and has a modern internal, removable pickup / pump unit and the cowl is a standard monster unit which I have always had a thing for.

The plan is to have a deep blue base, with a frame matching green center section on all three items, the line on the tank will only goto the fuel fill cap. The Ducati name will come from yellow late 60s ducati stickers.

[[File:StolenS4-Body-pre-paint.jpeg|link=File:StolenS4-Body-pre-paint.jpeg|center|700px]]
==Brake mod to clear the spokes==
The wire wheels on from the Sport Classic are very well built and therefore the spokes come off the very wide hub to get to the Rim, this made clearance a problem from the beginning. Ducati's solution was to use smaller, less good brake calipers which cleared the spokes and used an adapter. On my first go around I milled the calipers to clear the spokes which was required and which gave me proper braking at the time.

This time I was rather surprised to see that the SBK 100MM radial calipers "mostly" cleared the spokes, which the goldline calipers didn't at all. Regardless, I wanted more clearance incase a rock or a piece of a car gets in there, I don't want it to stop the from wheel.

Here you can see the caliper before being milled:

[[File:StolenS4-Caliper-pre.jpeg|link=File:StolenS4-Caliper-pre.jpeg |center|700px]]

And after being milled:

[[File:StolenS4-Caliper-post.jpeg|link=File:StolenS4-Caliper-post.jpeg |center|700px]]

These will be powder coated bright yellow which I am excited to see.

==Parts off to Powder 11/2025==
I have always loved taking this picture but I love taking the picture of the parts once they are returned far more.

We will have a a aqua frame and light bucket while having a aluminum silver swingarm, triples, clipons, rearset frames and highlight surround. We will also have yellow suspension link and calipers all around.

[[File:StolenS4-Pre-powder.jpeg|link=File:StolenS4-Pre-powder.jpeg|center|700px]]

Once again those purists out there will hate this thing but fuckem, its my bike and my wife bought it back for me and these are her favorite colors.

==Flywheel swap and a surprise 12/2025==
One of my favorite mods to these bikes is to ditch the flywheel. Lucky for me one popped up and I bought it. Pulling the stator cover off to install the flywheel, I was surprised to find and to remember the time I tossed a chain on this bike. It cracked the stator cover and luckily not the case.

[[File:Stolen4-statorcover.jpeg|link=File:Stolen4-statorcover.jpeg|center|700px]]

Here is the OE flywheel and my non-flywheel which is just big enough to hold the stator Mag and the starter bearing. While the flywheel mod makes the bike much more responsive, it can suffer around town at low revs, I don't love low revs so off it goes.

[[File:Stolen4-flywheels.jpeg|link=File:Stolen4-flywheels.jpeg|center|700px]]

Installed, you can hardly see the flywheel now.

[[File:Stolen4-flywheel-install.jpeg|link=File:Stolen4-flywheel-install.jpeg|center|700px]]

Prepping the replacement stator cover, next to original unit to the right.

[[File:Stolen4-statorcovers.jpeg|link=File:Stolen4-statorcovers.jpeg|center|700px]]

==Engine Degrease 12/2025==
After years of use and storage, these motors get pretty nasty and cleaning them up is a PITA. After plugging all the holes, you drag them outside, spray them down with degrees a few times, scrape and brush, then power wash the hell out of them.

Before starting:
[[File:Stolen4-engine-dirty-1.jpeg|link=File:Stolen4-engine-dirty-1.jpeg|center|700px]]

[[File:Stolen4-engine-dirty-2.jpeg|link=File:Stolen4-engine-dirty-2.jpeg|center|700px]]

After a lot of scrubbing and spraying and scrubbing and spraying:

[[File:Stolen4-engine-clean-1.jpeg|link=File:Stolen4-engine-clean-1.jpeg|center|700px]]

[[File:Stolen4-engine-clean-2.jpeg|link=File:Stolen4-engine-clean-2.jpeg|center|700px]]

[[File:Stolen4-engine-clean-3.jpeg|link=File:Stolen4-engine-clean-3.jpeg|center|700px]]

Next up is sanding, masking and painting.

==Back From Powder 12/2025==
It is always the best time when you get your parts back from being coated. All was well but there was an issue with the lower triple so that had to stay and be re-coated, which I will grab in the new year.

When I dropped the parts off I decided to go more teal than blue on this build and I am happy that I did. I think the Teal, Dark blue and Yellow will all play nicely with one another. My wife bought me this bike (but not all the parts and the rebuild!) so I think it is only suitable that the colors been in her color wheel.

[[File:StolenS4-Powder-Parts-1.jpeg|link=File:StolenS4-Powder-Parts-1.jpeg|center|700px]]

[[File:StolenS4-Powder-Parts-4.jpeg|link=File:StolenS4-Powder-Parts-4.jpeg|center|700px]]

Two things I really dislike on bikes are the colors black and chrome, because of this I coated all the aluminum parts and the headlight ring an aluminum like silver, here I wanted to see how the bucket and rim would play and I think it worked out nicely.

[[File:StolenS4-Powder-Parts-2.jpeg|link=File:StolenS4-Powder-Parts-2.jpeg|center|700px]]

Finally here is Ledger smiling ear to ear checking out his bike that we are building, he is excited because it holds two people..

[[File:StolenS4-Powder-Parts-3.jpeg|link=File:StolenS4-Powder-Parts-3.jpeg|center|700px]]

==Body back from paint 02/2026==
After getting all the body work prepped, I was able to get them to Sean ad SR customs to take it away. On the color front I went a little wild and chose colors my wife would like, in fact we copied a shampoo company who's colors we liked.

I had to toss the yellow in there, I wanted a little flare on this bike on top of the loud colors, this brought the coating of the calipers and suspension link, live a little I say.

This is also the first time I have ever used the 60' Ducati livery, I don't know why this time but thought it would play well with the roundness of the Monster tank. I do love the ducati double lines of the 70s but sometimes you need to do something new..

'''First thing to know is that this bike is not going to have a black seat (brown), just have the seat here to place parts on parts!'''

[[File:StolenS4-Body-left.jpeg|link=File:StolenS4-Body-left.jpeg|center|700px]]

Lots ohh parts!
[[File:StolenS4-Body-front.jpeg|link=File:StolenS4-Body-front.jpeg|center|700px]]

As you can see, I wanted to have some fun with the front fender, hoping it plays out!
[[File:StolenS4-Body-right.jpeg|link=File:StolenS4-Body-right.jpeg|center|700px]]

Wings and things...
[[File:StolenS4-Body-tank-right.jpeg|link=File:StolenS4-Body-tank-right.jpeg|center|700px]]

The monster tail will always be one of my favorite pieces of body work every to leave Bologna. Yuck to that seat!
[[File:StolenS4-Body-tail.jpeg|link=File:StolenS4-Body-tail.jpeg|center|700px]]

Finally you can see Sean's ability to match paint to powder. Very impressive.
[[File:StolenS4-Body-front-left.jpeg|link=File:StolenS4-Body-front-left.jpeg|center|700px]]

==Wheels and tires 02/2026==

I flipped back and fourth on the wheels for this bike, mainly because I assumed I could not make the 1098 radials clear the spokes. Before trying I bought 749 wheels and assumed that was my route. For the hell of it I tried the wire wheels and the radials and as you have seen posted above, they did in fact work!

One of my other favorite things Ducati has ever done was to introduce the Sport Classic line with Aluminum rimmed spoked wheels of a normal, modern street bike tire size. 20 years ago I bought two sets of these, one went on the Monster and other to storage. The monster wheels showed signs of age and salty air on the spokes. The second were brand new but have some tarnish on the clear I hope to clean up. I decided to go with the NOS units I had and wrapped them with killer Pirelli's. Is there anything better than a SBK tire on a wire wheel set? I don't think so.

[[File:StolenS4-Body-wheels.jpeg|link=File:StolenS4-Body-wheels.jpeg|center|700px]]

==Engine Mask and paint 02/2026==
Once again, a purist would break down these engines, sandblast and repaint. I opted to clean, sand and re-paint as it gives great results with a lot less time spent on an fine running motor.

Masking is a labor of love but one that you must take your time on. Remember I had to replace the side cover from the previous chain loss, this motor was all silver (as all were in this year) but the cover I used was from an earlier motor which still used the green color.

[[File:Stolen4-engine-mask1.jpeg|link=File:Stolen4-engine-mask1.jpeg|center|700px]]

[[File:Stolen4-engine-mask2.jpeg|link=File:Stolen4-engine-mask2.jpeg|center|700px]]

During the worst winter in 50 years in Rhode Island, it took weeks to get a window of time where I could paint where the temp was warm enough for the paint. Primer is laid down first, followed by color.

[[File:Stolen4-engine-primed.jpeg|link=File:Stolen4-engine-primed.jpeg|center|700px]]

[[File:Stolen4-engine-painted3.jpeg|link=File:Stolen4-engine-painted3.jpeg|center|700px]]

The next step in the prettying up of an old motor is a stainless bolt kit which will be done later.

==Initial Build 02/2026==
The second you bolt the frame back onto a Ducati motor, you are hyped for the second you get to ride the bike. At this point you know you are headed toward that day, a turning point if you will in the process of a rebuild. This is when parts start going back on. It took weeks, months and years to get to this point.

[[File:Stolen4-initial-build1.jpeg|link=File:Stolen4-initial-build1.jpeg|center|700px]]

[[File:Stolen4-initial-build2.jpeg|link=File:Stolen4-initial-build2.jpeg|center|700px]]

[[File:Stolen4-initial-build3.jpeg|link=File:Stolen4-initial-build3.jpeg|center|700px]]

[[File:Stolen4-initial-build4.jpeg|link=File:Stolen4-initial-build4.jpeg|center|700px]]

The downside is that every day you work on the bike is another day you ugly it up with all the required shit the bikes needs to run. Intake, airbox, radiator, wiring harness. It all adds up but these things are needed!

==Rolled out to see the light of day 03/2026==

With me running off for a few weeks for springbreak, I took the opertunity to get the bike rolling and activated the front braking system so that I can safely transport the bike to the Silas at Revenant Auto to fabricate the exhaust system for the bike.

It was very nice to see the bike in the daylight allbeit without all the ugly parts on it (airbox, wiring, radiator and cooling). Excuse the orange tow straps on the fork, this was just before loading to go.

==There is a story behind every bike I own 12/2024==

[[File:Stolen-S4-first-delivered.jpeg|link=File:Stolen-S4-first-delivered.jpeg|center|700px]]

==The buying spree begins 1/2025==

Because I know this bike so well and also know the platform in and out, before even riding this bike I did two things:
*Registered it
*Sourced most of the hard to find parts before taking it apart

The first challenge was a known one. The RI title I had last seen for this bike had a typo where an I was written as a 1 (common in RI long ago). The previous fellow decided to register it in Vermont and not deal with this. I went to the DMV, played dumb and had them check pictures of the stampings and fix the incorrect VIN.

As for sourcing parts, I went a bit haywire (shocker right). I decided go big or don't do it:
*Ohlins SBK fork with Radial bottoms (1198)
*Brembo 1198 radial calipers
*Brembo Radial master clutch and slave
*Speedymoto Monster to SBK triples
*Helibar clipons with a slight rise
*Termi spaghetti system with high mount Ti cans (Japan sourced, I have never seen these in the States, ever)
*Termi Monster 1100S cans, to be modded to fit the spaghetti systems while retaining the two up riding ability.
*Ohlins rear shock from an ST4s

The bummer about all this is the loss of the wire wheels. One of my favorite parts of this build is a monster with SC wheels but if I want radial brakes, the wheels must go, so they go because I like my brakes more than I like spoked wheels!

==Teardown and playing 10/2025==
With this bike, I didn't need to get her running, she is a runner. Right into the teardown and with it starts the mockup.

Here she is up on the lift, still basically a bike

[[File:Stolen4-teardown-1.jpeg|link=File:Stolen4-teardown-1.jpeg|center|700px]]

A little more extreme breakdown:

[[File:Stolen4-teardown-2.jpeg|link=File:Stolen4-teardown-2.jpeg|center|700px]]

This teardown will be jumping between teardown and mockup so unlike many of my other builds, this bike will look a lot more together throughout its evolution.

==Frontend build and mockup 10/2025==
For this bike I thought the 1098 / 1199 Ohlins with radials would look cool (and ride fucking awesome), the old FG43 bottoms are rad and all but really stand for the 90s and early 2000s. With the monster and all its swooping curves, the interegal radials will have a good look with the rest of the bike (I hope), additionally the final OG monster (S4RS) had radial bottoms but where a non SBK fork.

Here you can see them being serviced at Superbike services44 in New Hampshire. It always cracks me up to see the cost savings for ohlins when they only plate in gold the bits you see and not the others

[[File:Stolen4-tubes.jpeg|link=File:Stolen4-tubes.jpeg|center|700px]]

How many licks does it take to get to the center of a tootsie pop? The same can be said as to how many parts make up a front fork.

[[File:Stolen4-internals.jpeg|link=File:Stolen4-internals.jpeg|center|700px]]

When it came time to figure out the front end on this bike I was laser focused on an S4RS full front end but they were hard to find and not as good. I then remembered I had this fork in a pile but that it would require unique triples, lucky for me speedy moto dealt with this long ago and made a tripe for it. Im not a huge fan of the black anodizing but it is all I could get! Powder coating will resolve the black issue.

[[File:Stolen4-triples.jpeg|link=File:Stolen4-triples.jpeg|center|700px]]

For clipons, I went with a set of Helibars that came to me in a bulk buy. They are NOS and give me almost an inch up which should be good for 2up riding which this bike will be used for. I am also toying with wire wheels or 999 wheels, here you can see the 999 option.

[[File:Stolen4-front-test-1.jpeg|link=SFile:tolen4-front-test-1.jpeg|center|700px]]

It is always funny to see a bike with no headlight and no fairing, everything looks wrong.

Next up I have to figure out the wheel situation. Running a 999 rear in the ST / S4 swingarm is going to be challenging and at the the same time running a wire wheel in the 1198 fork has brake clearance challenges. More to come there in the coming weeks. My pref is wire but they are heavier. I don't know..

==Driveline Mockup 10/2025==
My plan was to run 749/999 wheels on this bike to allow for radial from calipers but much to my delight, the SC wire wheel spokes JUST clear the calipers, I will be milling them a tad just to allow for some more room.

Sticking with the wire wheels on this build makes me very happy, for some reason I have always loved the look of the SC aluminum hub / rim wheels along with road tires (which are not what are on these wheels right now). I have another set of wheels that are un-used that will be getting a set of road tires mounted in the coming weeks.

Monsters look funny without the big ass rearsets installed as you can see. I was thinking about doing away with them for the aesthetic but I want this bike to be good for two up riding so they will be sticking around.

[[File:Stolen4-driveline-mock-1.jpeg|link=File:Stolen4-driveline-mock-1.jpeg|center|700px]]

The ST4S rear shock mounted well and the rez plumbing clears the frame the way I had hoped. Here you see the rebound adjuster
[[File:Stolen4-driveline-mock-2.jpeg|link=File:Stolen4-driveline-mock-2.jpeg|center|700px]]

On the other side you see the compression adjust / rez with the line fitting well in the frame.
[[File:Stolen4-driveline-mock-3.jpeg|link=File:Stolen4-driveline-mock-3.jpeg|center|700px]]

Im testing the OG cast iron floating rotors on one side to see how the clearance is, which is perfect. For some reason I love these Tron looking rotors and am happy to have a bike I can run them on (6 bolt with the correct offset), all my other bikes are so modified I had to go other directions.
[[File:Stolen4-driveline-mock-4.jpeg|link=File:Stolen4-driveline-mock-4.jpeg|center|700px]]
==Body work planning 11/2025==
Talking about bodywork on a monster is the wrong way to put it but I had to come up with something. Those that know the monster know it's entire market is based on the lack of bodywork but here we will talk about the three major parts:
Tank: Monster S4RS
Front fender: Monster 1100S
Seat cowl: Monster S2R

To start I always like to switch it up with the front fenders on these builds so after poking around, I settled on a very modern looking 1100S monster fender, My fingers are crossed here. The Tank is from an S4RS so it is plastic and has a modern internal, removable pickup / pump unit and the cowl is a standard monster unit which I have always had a thing for.

The plan is to have a deep blue base, with a frame matching green center section on all three items, the line on the tank will only goto the fuel fill cap. The Ducati name will come from yellow late 60s ducati stickers.

[[File:StolenS4-Body-pre-paint.jpeg|link=File:StolenS4-Body-pre-paint.jpeg|center|700px]]
==Brake mod to clear the spokes==
The wire wheels on from the Sport Classic are very well built and therefore the spokes come off the very wide hub to get to the Rim, this made clearance a problem from the beginning. Ducati's solution was to use smaller, less good brake calipers which cleared the spokes and used an adapter. On my first go around I milled the calipers to clear the spokes which was required and which gave me proper braking at the time.

This time I was rather surprised to see that the SBK 100MM radial calipers "mostly" cleared the spokes, which the goldline calipers didn't at all. Regardless, I wanted more clearance incase a rock or a piece of a car gets in there, I don't want it to stop the from wheel.

Here you can see the caliper before being milled:

[[File:StolenS4-Caliper-pre.jpeg|link=File:StolenS4-Caliper-pre.jpeg |center|700px]]

And after being milled:

[[File:StolenS4-Caliper-post.jpeg|link=File:StolenS4-Caliper-post.jpeg |center|700px]]

These will be powder coated bright yellow which I am excited to see.

==Parts off to Powder 11/2025==
I have always loved taking this picture but I love taking the picture of the parts once they are returned far more.

We will have a a aqua frame and light bucket while having a aluminum silver swingarm, triples, clipons, rearset frames and highlight surround. We will also have yellow suspension link and calipers all around.

[[File:StolenS4-Pre-powder.jpeg|link=File:StolenS4-Pre-powder.jpeg|center|700px]]

Once again those purists out there will hate this thing but fuckem, its my bike and my wife bought it back for me and these are her favorite colors.

==Flywheel swap and a surprise 12/2025==
One of my favorite mods to these bikes is to ditch the flywheel. Lucky for me one popped up and I bought it. Pulling the stator cover off to install the flywheel, I was surprised to find and to remember the time I tossed a chain on this bike. It cracked the stator cover and luckily not the case.

[[File:Stolen4-statorcover.jpeg|link=File:Stolen4-statorcover.jpeg|center|700px]]

Here is the OE flywheel and my non-flywheel which is just big enough to hold the stator Mag and the starter bearing. While the flywheel mod makes the bike much more responsive, it can suffer around town at low revs, I don't love low revs so off it goes.

[[File:Stolen4-flywheels.jpeg|link=File:Stolen4-flywheels.jpeg|center|700px]]

Installed, you can hardly see the flywheel now.

[[File:Stolen4-flywheel-install.jpeg|link=File:Stolen4-flywheel-install.jpeg|center|700px]]

Prepping the replacement stator cover, next to original unit to the right.

[[File:Stolen4-statorcovers.jpeg|link=File:Stolen4-statorcovers.jpeg|center|700px]]

==Engine Degrease 12/2025==
After years of use and storage, these motors get pretty nasty and cleaning them up is a PITA. After plugging all the holes, you drag them outside, spray them down with degrees a few times, scrape and brush, then power wash the hell out of them.

Before starting:
[[File:Stolen4-engine-dirty-1.jpeg|link=File:Stolen4-engine-dirty-1.jpeg|center|700px]]

[[File:Stolen4-engine-dirty-2.jpeg|link=File:Stolen4-engine-dirty-2.jpeg|center|700px]]

After a lot of scrubbing and spraying and scrubbing and spraying:

[[File:Stolen4-engine-clean-1.jpeg|link=File:Stolen4-engine-clean-1.jpeg|center|700px]]

[[File:Stolen4-engine-clean-2.jpeg|link=File:Stolen4-engine-clean-2.jpeg|center|700px]]

[[File:Stolen4-engine-clean-3.jpeg|link=File:Stolen4-engine-clean-3.jpeg|center|700px]]

Next up is sanding, masking and painting.

==Back From Powder 12/2025==
It is always the best time when you get your parts back from being coated. All was well but there was an issue with the lower triple so that had to stay and be re-coated, which I will grab in the new year.

When I dropped the parts off I decided to go more teal than blue on this build and I am happy that I did. I think the Teal, Dark blue and Yellow will all play nicely with one another. My wife bought me this bike (but not all the parts and the rebuild!) so I think it is only suitable that the colors been in her color wheel.

[[File:StolenS4-Powder-Parts-1.jpeg|link=File:StolenS4-Powder-Parts-1.jpeg|center|700px]]

[[File:StolenS4-Powder-Parts-4.jpeg|link=File:StolenS4-Powder-Parts-4.jpeg|center|700px]]

Two things I really dislike on bikes are the colors black and chrome, because of this I coated all the aluminum parts and the headlight ring an aluminum like silver, here I wanted to see how the bucket and rim would play and I think it worked out nicely.

[[File:StolenS4-Powder-Parts-2.jpeg|link=File:StolenS4-Powder-Parts-2.jpeg|center|700px]]

Finally here is Ledger smiling ear to ear checking out his bike that we are building, he is excited because it holds two people..

[[File:StolenS4-Powder-Parts-3.jpeg|link=File:StolenS4-Powder-Parts-3.jpeg|center|700px]]

==Body back from paint 02/2026==
After getting all the body work prepped, I was able to get them to Sean ad SR customs to take it away. On the color front I went a little wild and chose colors my wife would like, in fact we copied a shampoo company who's colors we liked.

I had to toss the yellow in there, I wanted a little flare on this bike on top of the loud colors, this brought the coating of the calipers and suspension link, live a little I say.

This is also the first time I have ever used the 60' Ducati livery, I don't know why this time but thought it would play well with the roundness of the Monster tank. I do love the ducati double lines of the 70s but sometimes you need to do something new..

'''First thing to know is that this bike is not going to have a black seat (brown), just have the seat here to place parts on parts!'''

[[File:StolenS4-Body-left.jpeg|link=File:StolenS4-Body-left.jpeg|center|700px]]

Lots ohh parts!
[[File:StolenS4-Body-front.jpeg|link=File:StolenS4-Body-front.jpeg|center|700px]]

As you can see, I wanted to have some fun with the front fender, hoping it plays out!
[[File:StolenS4-Body-right.jpeg|link=File:StolenS4-Body-right.jpeg|center|700px]]

Wings and things...
[[File:StolenS4-Body-tank-right.jpeg|link=File:StolenS4-Body-tank-right.jpeg|center|700px]]

The monster tail will always be one of my favorite pieces of body work every to leave Bologna. Yuck to that seat!
[[File:StolenS4-Body-tail.jpeg|link=File:StolenS4-Body-tail.jpeg|center|700px]]

Finally you can see Sean's ability to match paint to powder. Very impressive.
[[File:StolenS4-Body-front-left.jpeg|link=File:StolenS4-Body-front-left.jpeg|center|700px]]

==Wheels and tires 02/2026==

I flipped back and fourth on the wheels for this bike, mainly because I assumed I could not make the 1098 radials clear the spokes. Before trying I bought 749 wheels and assumed that was my route. For the hell of it I tried the wire wheels and the radials and as you have seen posted above, they did in fact work!

One of my other favorite things Ducati has ever done was to introduce the Sport Classic line with Aluminum rimmed spoked wheels of a normal, modern street bike tire size. 20 years ago I bought two sets of these, one went on the Monster and other to storage. The monster wheels showed signs of age and salty air on the spokes. The second were brand new but have some tarnish on the clear I hope to clean up. I decided to go with the NOS units I had and wrapped them with killer Pirelli's. Is there anything better than a SBK tire on a wire wheel set? I don't think so.

[[File:StolenS4-Body-wheels.jpeg|link=File:StolenS4-Body-wheels.jpeg|center|700px]]

==Engine Mask and paint 02/2026==
Once again, a purist would break down these engines, sandblast and repaint. I opted to clean, sand and re-paint as it gives great results with a lot less time spent on an fine running motor.

Masking is a labor of love but one that you must take your time on. Remember I had to replace the side cover from the previous chain loss, this motor was all silver (as all were in this year) but the cover I used was from an earlier motor which still used the green color.

[[File:Stolen4-engine-mask1.jpeg|link=File:Stolen4-engine-mask1.jpeg|center|700px]]

[[File:Stolen4-engine-mask2.jpeg|link=File:Stolen4-engine-mask2.jpeg|center|700px]]

During the worst winter in 50 years in Rhode Island, it took weeks to get a window of time where I could paint where the temp was warm enough for the paint. Primer is laid down first, followed by color.

[[File:Stolen4-engine-primed.jpeg|link=File:Stolen4-engine-primed.jpeg|center|700px]]

The next step in the prettying up of an old motor is a stainless bolt kit which will be done later.

==Initial Build 02/2026==
The second you bolt the frame back onto a Ducati motor, you are hyped for the second you get to ride the bike. At this point you know you are headed toward that day, a turning point if you will in the process of a rebuild. This is when parts start going back on. It took weeks, months and years to get to this point.

[[File:Stolen4-initial-build1.jpeg|link=File:Stolen4-initial-build1.jpeg|center|700px]]

[[File:Stolen4-initial-build2.jpeg|link=File:Stolen4-initial-build2.jpeg|center|700px]]

[[File:Stolen4-initial-build4.jpeg|link=File:Stolen4-initial-build4.jpeg|center|700px]]

The downside is that every day you work on the bike is another day you ugly it up with all the required shit the bikes needs to run. Intake, airbox, radiator, wiring harness. It all adds up but these things are needed!

==Rolled out to see the light of day 03/2026==

With me running off for a few weeks for springbreak, I took the opertunity to get the bike rolling and activated the front braking system so that I can safely transport the bike to the Silas at Revenant Auto to fabricate the exhaust system for the bike.

It was very nice to see the bike in the daylight allbeit without all the ugly parts on it (airbox, wiring, radiator and cooling). Excuse the orange tow straps on the fork, this was just before loading to go.

==There is a story behind every bike I own 12/2024==

Warning, 17mile story ahead.

Long long ago when I was building the 888LTD for Wally, there was a need for a set of 5spoke Marchesini wheels which many know are impossible to find for the 851/888 platform. My solution at the time was to find an S4 and buy it for the wheels which we did. I found a decent bike in upstate NY and drove out and paid cash for it (well, wally paid cash for it). The bike was your base model Monster S4, all stock, red, a good bike.

After stealing the wheels I was left wondering what fun could be had with a monster when left to my own devices and I think we found the way. I sourced a set of Sport classic wire wheels and a handful of other bits and started to goto work on the bike. The first thing to do was to paint the red away which I did with BMW's laguna sec blue (the same color as my race bikes at the time), then was the wheel swap, slipper clutch, power commander, clip ons and a saw to the exhaust.

The result was awesome: A loud, fun little run around with a decent amount of power. One of the biggest challanges was getting the gold line brakes to clear the spokes on the wire wheels (remember Ducati's solution to this was to use smaller, less brakes which I was having none of). My solution was to mill down the calipers until they cleared, the risk was blowing into the backs of the calipers and making a mess of my mill (this never happened luckly!)

The bike was totally stock when purchased, here it is in the back of the truck on its way to my shop in 2007

[[File:SSPX0048.jpg|link=File:SSPX0048.jpg|center|700px]]

I quickly took the bike apart, installed clip-ons, chopped the pipes, added wire wheels and a few other things

[[File:Monster3.jpg|link=File:Monster3.jpg|center|700px]]

I then painted the bike BMW Laguna Seca Blue which was my favorite. Here was the bike in 2008 when it was in my possession still

[[File:StolenS4-Front.jpg|link=File:StolenS4-Front.jpg|center|700px]]

Here you can see my mill work on the calipers to get them to clear the spokes. I know, Im nuts!

[[File:StolenS4-Caliper.jpg|link=File:StolenS4-Caliper.jpg|center|700px]]

At the time I lived with a very close friend who I trusted and who didn't have a bike. I offered the bike to him to use and was foolish enough to give him the title and let him register the bike, which he did. A time later he and I had a big falling out where I offered for him to keep the bike, only to be told "Fuck you and your bike, I don't want it". A few weeks later he moved out and the bike left with him which surprised me, after all "fuck me and my bike" right? Well, I tried for 6 or 7 years to get the bike back and was repeatedly told I could buy the bike back which I refused to do.

Time went on and the guy sold or gave the bike to a fellow, who sold or gave the bike to another fellow. Rumors of the bike being for sale floated around and I even tossed a number out there for the bike but it was far too high for what I knew the bike was worth, so I passed. My friend Rocket got a call from the guy who had the bike and was offered the thing at more than half what I was offered it (this happens to me a lot) and Rocket called me to get the bike. I was so pissed about the number that I told him to shove it (so that he would tell the guy who had it to shove it) and that was the end of it. So I thought.

==So there I was, a week before Christmas 12/2024==

Working around the house, doing shit. Im talking to my wife and I hear this noise, a noise that is hard not to recognize, and my wife's smile which is a "I got you" smile. I start laughing and walk out to find Rocket in the driveway, sitting on the S4 in 20degree wheather freezing his ass off but cracking up! She had bought me the bike! Her words were: "Now the collection is all back together". My wife is the shit but little did she know that this move was going to cost me a ton of cash!

Here she is when it was returned to me. The Black livery is questionable, the clip-ons have been removed and a lot of other bits had been changed but overall she was still the bike I had last seen her as.

[[File:Stolen-S4-first-delivered.jpeg|link=File:Stolen-S4-first-delivered.jpeg|center|700px]]

==The buying spree begins 1/2025==

Because I know this bike so well and also know the platform in and out, before even riding this bike I did two things:
*Registered it
*Sourced most of the hard to find parts before taking it apart

The first challenge was a known one. The RI title I had last seen for this bike had a typo where an I was written as a 1 (common in RI long ago). The previous fellow decided to register it in Vermont and not deal with this. I went to the DMV, played dumb and had them check pictures of the stampings and fix the incorrect VIN.

As for sourcing parts, I went a bit haywire (shocker right). I decided go big or don't do it:
*Ohlins SBK fork with Radial bottoms (1198)
*Brembo 1198 radial calipers
*Brembo Radial master clutch and slave
*Speedymoto Monster to SBK triples
*Helibar clipons with a slight rise
*Termi spaghetti system with high mount Ti cans (Japan sourced, I have never seen these in the States, ever)
*Termi Monster 1100S cans, to be modded to fit the spaghetti systems while retaining the two up riding ability.
*Ohlins rear shock from an ST4s

The bummer about all this is the loss of the wire wheels. One of my favorite parts of this build is a monster with SC wheels but if I want radial brakes, the wheels must go, so they go because I like my brakes more than I like spoked wheels!

==Teardown and playing 10/2025==
With this bike, I didn't need to get her running, she is a runner. Right into the teardown and with it starts the mockup.

Here she is up on the lift, still basically a bike

[[File:Stolen4-teardown-1.jpeg|link=File:Stolen4-teardown-1.jpeg|center|700px]]

A little more extreme breakdown:

[[File:Stolen4-teardown-2.jpeg|link=File:Stolen4-teardown-2.jpeg|center|700px]]

This teardown will be jumping between teardown and mockup so unlike many of my other builds, this bike will look a lot more together throughout its evolution.

==Frontend build and mockup 10/2025==
For this bike I thought the 1098 / 1199 Ohlins with radials would look cool (and ride fucking awesome), the old FG43 bottoms are rad and all but really stand for the 90s and early 2000s. With the monster and all its swooping curves, the interegal radials will have a good look with the rest of the bike (I hope), additionally the final OG monster (S4RS) had radial bottoms but where a non SBK fork.

Here you can see them being serviced at Superbike services44 in New Hampshire. It always cracks me up to see the cost savings for ohlins when they only plate in gold the bits you see and not the others

[[File:Stolen4-tubes.jpeg|link=File:Stolen4-tubes.jpeg|center|700px]]

How many licks does it take to get to the center of a tootsie pop? The same can be said as to how many parts make up a front fork.

[[File:Stolen4-internals.jpeg|link=File:Stolen4-internals.jpeg|center|700px]]

When it came time to figure out the front end on this bike I was laser focused on an S4RS full front end but they were hard to find and not as good. I then remembered I had this fork in a pile but that it would require unique triples, lucky for me speedy moto dealt with this long ago and made a tripe for it. Im not a huge fan of the black anodizing but it is all I could get! Powder coating will resolve the black issue.

[[File:Stolen4-triples.jpeg|link=File:Stolen4-triples.jpeg|center|700px]]

For clipons, I went with a set of Helibars that came to me in a bulk buy. They are NOS and give me almost an inch up which should be good for 2up riding which this bike will be used for. I am also toying with wire wheels or 999 wheels, here you can see the 999 option.

[[File:Stolen4-front-test-1.jpeg|link=SFile:tolen4-front-test-1.jpeg|center|700px]]

It is always funny to see a bike with no headlight and no fairing, everything looks wrong.

Next up I have to figure out the wheel situation. Running a 999 rear in the ST / S4 swingarm is going to be challenging and at the the same time running a wire wheel in the 1098 fork has brake clearance challenges. More to come there in the coming weeks. My pref is wire but they are heavier. I don't know..

==Driveline Mockup 10/2025==
My plan was to run 749/999 wheels on this bike to allow for radial from calipers but much to my delight, the SC wire wheel spokes JUST clear the calipers, I will be milling them a tad just to allow for some more room.

Sticking with the wire wheels on this build makes me very happy, for some reason I have always loved the look of the SC aluminum hub / rim wheels along with road tires (which are not what are on these wheels right now). I have another set of wheels that are un-used that will be getting a set of road tires mounted in the coming weeks.

Monsters look funny without the big ass rearsets installed as you can see. I was thinking about doing away with them for the aesthetic but I want this bike to be good for two up riding so they will be sticking around.

The ST4S rear shock mounted well and the rez plumbing clears the frame the way I had hoped. Here you see the rebound adjuster

On the other side you see the compression adjust / rez with the line fitting well in the frame.

Im testing the OG cast iron floating rotors on one side to see how the clearance is, which is perfect. For some reason I love these Tron looking rotors and am happy to have a bike I can run them on (6 bolt with the correct offset), all my other bikes are so modified I had to go other directions.

==Body work planning 11/2025==
Talking about bodywork on a monster is the wrong way to put it but I had to come up with something. Those that know the monster know it's entire market is based on the lack of bodywork but here we will talk about the three major parts:
Tank: Monster S4RS
Front fender: Monster 1100S
Seat cowl: Monster S2R

To start I always like to switch it up with the front fenders on these builds so after poking around, I settled on a very modern looking 1100S monster fender, My fingers are crossed here. The Tank is from an S4RS so it is plastic and has a modern internal, removable pickup / pump unit and the cowl is a standard monster unit which I have always had a thing for.

The plan is to have a deep blue base, with a frame matching green center section on all three items, the line on the tank will only goto the fuel fill cap. The Ducati name will come from yellow late 60s ducati stickers.

[[File:StolenS4-Body-pre-paint.jpeg|link=File:StolenS4-Body-pre-paint.jpeg|center|700px]]
==Brake mod to clear the spokes==
The wire wheels on from the Sport Classic are very well built and therefore the spokes come off the very wide hub to get to the Rim, this made clearance a problem from the beginning. Ducati's solution was to use smaller, less good brake calipers which cleared the spokes and used an adapter. On my first go around I milled the calipers to clear the spokes which was required and which gave me proper braking at the time.

This time I was rather surprised to see that the SBK 100MM radial calipers "mostly" cleared the spokes, which the goldline calipers didn't at all. Regardless, I wanted more clearance incase a rock or a piece of a car gets in there, I don't want it to stop the from wheel.

Here you can see the caliper before being milled:

[[File:StolenS4-Caliper-pre.jpeg|link=File:StolenS4-Caliper-pre.jpeg |center|700px]]

And after being milled:

[[File:StolenS4-Caliper-post.jpeg|link=File:StolenS4-Caliper-post.jpeg |center|700px]]

These will be powder coated bright yellow which I am excited to see.

==Parts off to Powder 11/2025==
I have always loved taking this picture but I love taking the picture of the parts once they are returned far more.

We will have a a aqua frame and light bucket while having a aluminum silver swingarm, triples, clipons, rearset frames and highlight surround. We will also have yellow suspension link and calipers all around.

[[File:StolenS4-Pre-powder.jpeg|link=File:StolenS4-Pre-powder.jpeg|center|700px]]

Once again those purists out there will hate this thing but fuckem, its my bike and my wife bought it back for me and these are her favorite colors.

==Flywheel swap and a surprise 12/2025==
One of my favorite mods to these bikes is to ditch the flywheel. Lucky for me one popped up and I bought it. Pulling the stator cover off to install the flywheel, I was surprised to find and to remember the time I tossed a chain on this bike. It cracked the stator cover and luckily not the case.

[[File:Stolen4-statorcover.jpeg|link=File:Stolen4-statorcover.jpeg|center|700px]]

Here is the OE flywheel and my non-flywheel which is just big enough to hold the stator Mag and the starter bearing. While the flywheel mod makes the bike much more responsive, it can suffer around town at low revs, I don't love low revs so off it goes.

[[File:Stolen4-flywheels.jpeg|link=File:Stolen4-flywheels.jpeg|center|700px]]

Installed, you can hardly see the flywheel now.

[[File:Stolen4-flywheel-install.jpeg|link=File:Stolen4-flywheel-install.jpeg|center|700px]]

Prepping the replacement stator cover, next to original unit to the right.

[[File:Stolen4-statorcovers.jpeg|link=File:Stolen4-statorcovers.jpeg|center|700px]]

==Engine Degrease 12/2025==
After years of use and storage, these motors get pretty nasty and cleaning them up is a PITA. After plugging all the holes, you drag them outside, spray them down with degrees a few times, scrape and brush, then power wash the hell out of them.

Before starting:

[[File:Stolen4-engine-dirty-2.jpeg|link=File:Stolen4-engine-dirty-2.jpeg|center|700px]]

After a lot of scrubbing and spraying and scrubbing and spraying:

[[File:Stolen4-engine-clean-1.jpeg|link=File:Stolen4-engine-clean-1.jpeg|center|700px]]

[[File:Stolen4-engine-clean-2.jpeg|link=File:Stolen4-engine-clean-2.jpeg|center|700px]]

[[File:Stolen4-engine-clean-3.jpeg|link=File:Stolen4-engine-clean-3.jpeg|center|700px]]

Next up is sanding, masking and painting.

==Back From Powder 12/2025==
It is always the best time when you get your parts back from being coated. All was well but there was an issue with the lower triple so that had to stay and be re-coated, which I will grab in the new year.

When I dropped the parts off I decided to go more teal than blue on this build and I am happy that I did. I think the Teal, Dark blue and Yellow will all play nicely with one another. My wife bought me this bike (but not all the parts and the rebuild!) so I think it is only suitable that the colors been in her color wheel.

[[File:StolenS4-Powder-Parts-1.jpeg|link=File:StolenS4-Powder-Parts-1.jpeg|center|700px]]

[[File:StolenS4-Powder-Parts-4.jpeg|link=File:StolenS4-Powder-Parts-4.jpeg|center|700px]]

Two things I really dislike on bikes are the colors black and chrome, because of this I coated all the aluminum parts and the headlight ring an aluminum like silver, here I wanted to see how the bucket and rim would play and I think it worked out nicely.

[[File:StolenS4-Powder-Parts-2.jpeg|link=File:StolenS4-Powder-Parts-2.jpeg|center|700px]]

Finally here is Ledger smiling ear to ear checking out his bike that we are building, he is excited because it holds two people..

[[File:StolenS4-Powder-Parts-3.jpeg|link=File:StolenS4-Powder-Parts-3.jpeg|center|700px]]

==Body back from paint 02/2026==
After getting all the body work prepped, I was able to get them to Sean ad SR customs to take it away. On the color front I went a little wild and chose colors my wife would like, in fact we copied a shampoo company who's colors we liked.

I had to toss the yellow in there, I wanted a little flare on this bike on top of the loud colors, this brought the coating of the calipers and suspension link, live a little I say.

This is also the first time I have ever used the 60' Ducati livery, I don't know why this time but thought it would play well with the roundness of the Monster tank. I do love the ducati double lines of the 70s but sometimes you need to do something new..

'''First thing to know is that this bike is not going to have a black seat (brown), just have the seat here to place parts on parts!'''

[[File:StolenS4-Body-left.jpeg|link=File:StolenS4-Body-left.jpeg|center|700px]]

Lots ohh parts!
[[File:StolenS4-Body-front.jpeg|link=File:StolenS4-Body-front.jpeg|center|700px]]

As you can see, I wanted to have some fun with the front fender, hoping it plays out!
[[File:StolenS4-Body-right.jpeg|link=File:StolenS4-Body-right.jpeg|center|700px]]

Wings and things...
[[File:StolenS4-Body-tank-right.jpeg|link=File:StolenS4-Body-tank-right.jpeg|center|700px]]

The monster tail will always be one of my favorite pieces of body work every to leave Bologna. Yuck to that seat!
[[File:StolenS4-Body-tail.jpeg|link=File:StolenS4-Body-tail.jpeg|center|700px]]

Finally you can see Sean's ability to match paint to powder. Very impressive.
[[File:StolenS4-Body-front-left.jpeg|link=File:StolenS4-Body-front-left.jpeg|center|700px]]

==Wheels and tires 02/2026==

I flipped back and fourth on the wheels for this bike, mainly because I assumed I could not make the 1098 radials clear the spokes. Before trying I bought 749 wheels and assumed that was my route. For the hell of it I tried the wire wheels and the radials and as you have seen posted above, they did in fact work!

One of my other favorite things Ducati has ever done was to introduce the Sport Classic line with Aluminum rimmed spoked wheels of a normal, modern street bike tire size. 20 years ago I bought two sets of these, one went on the Monster and other to storage. The monster wheels showed signs of age and salty air on the spokes. The second were brand new but have some tarnish on the clear I hope to clean up. I decided to go with the NOS units I had and wrapped them with killer Pirelli's. Is there anything better than a SBK tire on a wire wheel set? I don't think so.

[[File:StolenS4-Body-wheels.jpeg|link=File:StolenS4-Body-wheels.jpeg|center|700px]]

==Engine Mask and paint 02/2026==
Once again, a purist would break down these engines, sandblast and repaint. I opted to clean, sand and re-paint as it gives great results with a lot less time spent on an fine running motor.

Masking is a labor of love but one that you must take your time on. Remember I had to replace the side cover from the previous chain loss, this motor was all silver (as all were in this year) but the cover I used was from an earlier motor which still used the green color.

[[File:Stolen4-engine-mask1.jpeg|link=File:Stolen4-engine-mask1.jpeg|center|700px]]

[[File:Stolen4-engine-mask2.jpeg|link=File:Stolen4-engine-mask2.jpeg|center|700px]]

During the worst winter in 50 years in Rhode Island, it took weeks to get a window of time where I could paint where the temp was warm enough for the paint. Primer is laid down first, followed by color.

The next step in the prettying up of an old motor is a stainless bolt kit which will be done later.

==Initial Build 02/2026==
The second you bolt the frame back onto a Ducati motor, you are hyped for the second you get to ride the bike. At this point you know you are headed toward that day, a turning point if you will in the process of a rebuild. This is when parts start going back on. It took weeks, months and years to get to this point.

[[File:Stolen4-initial-build1.jpeg|link=File:Stolen4-initial-build1.jpeg|center|700px]]

[[File:Stolen4-initial-build2.jpeg|link=File:Stolen4-initial-build2.jpeg|center|700px]]

[[File:Stolen4-initial-build4.jpeg|link=File:Stolen4-initial-build4.jpeg|center|700px]]

The downside is that every day you work on the bike is another day you ugly it up with all the required shit the bikes needs to run. Intake, airbox, radiator, wiring harness. It all adds up but these things are needed!

==Rolled out to see the light of day 03/2026==

With me running off for a few weeks for springbreak, I took the opertunity to get the bike rolling and activated the front braking system so that I can safely transport the bike to the Silas at Revenant Auto to fabricate the exhaust system for the bike.

It was very nice to see the bike in the daylight allbeit without all the ugly parts on it (airbox, wiring, radiator and cooling). Excuse the orange tow straps on the fork, this was just before loading to go.

==There is a story behind every bike I own 12/2024==

Warning, 17mile story ahead.

Long long ago when I was building the 888LTD for Wally, there was a need for a set of 5spoke Marchesini wheels which many know are impossible to find for the 851/888 platform. My solution at the time was to find an S4 and buy it for the wheels which we did. I found a decent bike in upstate NY and drove out and paid cash for it (well, wally paid cash for it). The bike was your base model Monster S4, all stock, red, a good bike.

After stealing the wheels I was left wondering what fun could be had with a monster when left to my own devices and I think we found the way. I sourced a set of Sport classic wire wheels and a handful of other bits and started to goto work on the bike. The first thing to do was to paint the red away which I did with BMW's laguna sec blue (the same color as my race bikes at the time), then was the wheel swap, slipper clutch, power commander, clip ons and a saw to the exhaust.

The result was awesome: A loud, fun little run around with a decent amount of power. One of the biggest challanges was getting the gold line brakes to clear the spokes on the wire wheels (remember Ducati's solution to this was to use smaller, less brakes which I was having none of). My solution was to mill down the calipers until they cleared, the risk was blowing into the backs of the calipers and making a mess of my mill (this never happened luckly!)

The bike was totally stock when purchased, here it is in the back of the truck on its way to my shop in 2007

[[File:SSPX0048.jpg|link=File:SSPX0048.jpg|center|700px]]

I quickly took the bike apart, installed clip-ons, chopped the pipes, added wire wheels and a few other things

[[File:Monster3.jpg|link=File:Monster3.jpg|center|700px]]

I then painted the bike BMW Laguna Seca Blue which was my favorite. Here was the bike in 2008 when it was in my possession still

[[File:StolenS4-FrontRight.jpg|link=File:StolenS4-FrontRight.jpg|center|700px]]

[[File:StolenS4-Front.jpg|link=File:StolenS4-Front.jpg|center|700px]]

Here you can see my mill work on the calipers to get them to clear the spokes. I know, Im nuts!

[[File:StolenS4-Caliper.jpg|link=File:StolenS4-Caliper.jpg|center|700px]]

At the time I lived with a very close friend who I trusted and who didn't have a bike. I offered the bike to him to use and was foolish enough to give him the title and let him register the bike, which he did. A time later he and I had a big falling out where I offered for him to keep the bike, only to be told "Fuck you and your bike, I don't want it". A few weeks later he moved out and the bike left with him which surprised me, after all "fuck me and my bike" right? Well, I tried for 6 or 7 years to get the bike back and was repeatedly told I could buy the bike back which I refused to do.

Time went on and the guy sold or gave the bike to a fellow, who sold or gave the bike to another fellow. Rumors of the bike being for sale floated around and I even tossed a number out there for the bike but it was far too high for what I knew the bike was worth, so I passed. My friend Rocket got a call from the guy who had the bike and was offered the thing at more than half what I was offered it (this happens to me a lot) and Rocket called me to get the bike. I was so pissed about the number that I told him to shove it (so that he would tell the guy who had it to shove it) and that was the end of it. So I thought.

==So there I was, a week before Christmas 12/2024==

Working around the house, doing shit. Im talking to my wife and I hear this noise, a noise that is hard not to recognize, and my wife's smile which is a "I got you" smile. I start laughing and walk out to find Rocket in the driveway, sitting on the S4 in 20degree wheather freezing his ass off but cracking up! She had bought me the bike! Her words were: "Now the collection is all back together". My wife is the shit but little did she know that this move was going to cost me a ton of cash!

Here she is when it was returned to me. The Black livery is questionable, the clip-ons have been removed and a lot of other bits had been changed but overall she was still the bike I had last seen her as.

[[File:Stolen-S4-first-delivered.jpeg|link=File:Stolen-S4-first-delivered.jpeg|center|700px]]

==The buying spree begins 1/2025==

Because I know this bike so well and also know the platform in and out, before even riding this bike I did two things:
*Registered it
*Sourced most of the hard to find parts before taking it apart

The first challenge was a known one. The RI title I had last seen for this bike had a typo where an I was written as a 1 (common in RI long ago). The previous fellow decided to register it in Vermont and not deal with this. I went to the DMV, played dumb and had them check pictures of the stampings and fix the incorrect VIN.

As for sourcing parts, I went a bit haywire (shocker right). I decided go big or don't do it:
*Ohlins SBK fork with Radial bottoms (1198)
*Brembo 1198 radial calipers
*Brembo Radial master clutch and slave
*Speedymoto Monster to SBK triples
*Helibar clipons with a slight rise
*Termi spaghetti system with high mount Ti cans (Japan sourced, I have never seen these in the States, ever)
*Termi Monster 1100S cans, to be modded to fit the spaghetti systems while retaining the two up riding ability.
*Ohlins rear shock from an ST4s

The bummer about all this is the loss of the wire wheels. One of my favorite parts of this build is a monster with SC wheels but if I want radial brakes, the wheels must go, so they go because I like my brakes more than I like spoked wheels!

==Teardown and playing 10/2025==
With this bike, I didn't need to get her running, she is a runner. Right into the teardown and with it starts the mockup.

Here she is up on the lift, still basically a bike

[[File:Stolen4-teardown-1.jpeg|link=File:Stolen4-teardown-1.jpeg|center|700px]]

A little more extreme breakdown:

[[File:Stolen4-teardown-2.jpeg|link=File:Stolen4-teardown-2.jpeg|center|700px]]

This teardown will be jumping between teardown and mockup so unlike many of my other builds, this bike will look a lot more together throughout its evolution.

==Frontend build and mockup 10/2025==
For this bike I thought the 1098 / 1199 Ohlins with radials would look cool (and ride fucking awesome), the old FG43 bottoms are rad and all but really stand for the 90s and early 2000s. With the monster and all its swooping curves, the interegal radials will have a good look with the rest of the bike (I hope), additionally the final OG monster (S4RS) had radial bottoms but where a non SBK fork.

Here you can see them being serviced at Superbike services44 in New Hampshire. It always cracks me up to see the cost savings for ohlins when they only plate in gold the bits you see and not the others

[[File:Stolen4-tubes.jpeg|link=File:Stolen4-tubes.jpeg|center|700px]]

How many licks does it take to get to the center of a tootsie pop? The same can be said as to how many parts make up a front fork.

[[File:Stolen4-internals.jpeg|link=File:Stolen4-internals.jpeg|center|700px]]

When it came time to figure out the front end on this bike I was laser focused on an S4RS full front end but they were hard to find and not as good. I then remembered I had this fork in a pile but that it would require unique triples, lucky for me speedy moto dealt with this long ago and made a tripe for it. Im not a huge fan of the black anodizing but it is all I could get! Powder coating will resolve the black issue.

[[File:Stolen4-triples.jpeg|link=File:Stolen4-triples.jpeg|center|700px]]

For clipons, I went with a set of Helibars that came to me in a bulk buy. They are NOS and give me almost an inch up which should be good for 2up riding which this bike will be used for. I am also toying with wire wheels or 999 wheels, here you can see the 999 option.

[[File:Stolen4-front-test-1.jpeg|link=SFile:tolen4-front-test-1.jpeg|center|700px]]

It is always funny to see a bike with no headlight and no fairing, everything looks wrong.

Next up I have to figure out the wheel situation. Running a 999 rear in the ST / S4 swingarm is going to be challenging and at the the same time running a wire wheel in the 1098 fork has brake clearance challenges. More to come there in the coming weeks. My pref is wire but they are heavier. I don't know..

==Driveline Mockup 10/2025==
My plan was to run 749/999 wheels on this bike to allow for radial from calipers but much to my delight, the SC wire wheel spokes JUST clear the calipers, I will be milling them a tad just to allow for some more room.

Sticking with the wire wheels on this build makes me very happy, for some reason I have always loved the look of the SC aluminum hub / rim wheels along with road tires (which are not what are on these wheels right now). I have another set of wheels that are un-used that will be getting a set of road tires mounted in the coming weeks.

Monsters look funny without the big ass rearsets installed as you can see. I was thinking about doing away with them for the aesthetic but I want this bike to be good for two up riding so they will be sticking around.

[[File:Stolen4-driveline-mock-1.jpeg|link=File:Stolen4-driveline-mock-1.jpeg|center|700px]]

The ST4S rear shock mounted well and the rez plumbing clears the frame the way I had hoped. Here you see the rebound adjuster
[[File:Stolen4-driveline-mock-2.jpeg|link=File:Stolen4-driveline-mock-2.jpeg|center|700px]]

On the other side you see the compression adjust / rez with the line fitting well in the frame.
[[File:Stolen4-driveline-mock-3.jpeg|link=File:Stolen4-driveline-mock-3.jpeg|center|700px]]

Im testing the OG cast iron floating rotors on one side to see how the clearance is, which is perfect. For some reason I love these Tron looking rotors and am happy to have a bike I can run them on (6 bolt with the correct offset), all my other bikes are so modified I had to go other directions.
[[File:Stolen4-driveline-mock-4.jpeg|link=File:Stolen4-driveline-mock-4.jpeg|center|700px]]
==Body work planning 11/2025==
Talking about bodywork on a monster is the wrong way to put it but I had to come up with something. Those that know the monster know it's entire market is based on the lack of bodywork but here we will talk about the three major parts:
Tank: Monster S4RS
Front fender: Monster 1100S
Seat cowl: Monster S2R

To start I always like to switch it up with the front fenders on these builds so after poking around, I settled on a very modern looking 1100S monster fender, My fingers are crossed here. The Tank is from an S4RS so it is plastic and has a modern internal, removable pickup / pump unit and the cowl is a standard monster unit which I have always had a thing for.

The plan is to have a deep blue base, with a frame matching green center section on all three items, the line on the tank will only goto the fuel fill cap. The Ducati name will come from yellow late 60s ducati stickers.

[[File:StolenS4-Body-pre-paint.jpeg|link=File:StolenS4-Body-pre-paint.jpeg|center|700px]]
==Brake mod to clear the spokes==
The wire wheels on from the Sport Classic are very well built and therefore the spokes come off the very wide hub to get to the Rim, this made clearance a problem from the beginning. Ducati's solution was to use smaller, less good brake calipers which cleared the spokes and used an adapter. On my first go around I milled the calipers to clear the spokes which was required and which gave me proper braking at the time.

This time I was rather surprised to see that the SBK 100MM radial calipers "mostly" cleared the spokes, which the goldline calipers didn't at all. Regardless, I wanted more clearance incase a rock or a piece of a car gets in there, I don't want it to stop the from wheel.

Here you can see the caliper before being milled:

[[File:StolenS4-Caliper-pre.jpeg|link=File:StolenS4-Caliper-pre.jpeg |center|700px]]

And after being milled:

[[File:StolenS4-Caliper-post.jpeg|link=File:StolenS4-Caliper-post.jpeg |center|700px]]

These will be powder coated bright yellow which I am excited to see.

==Parts off to Powder 11/2025==
I have always loved taking this picture but I love taking the picture of the parts once they are returned far more.

We will have a a aqua frame and light bucket while having a aluminum silver swingarm, triples, clipons, rearset frames and highlight surround. We will also have yellow suspension link and calipers all around.

[[File:StolenS4-Pre-powder.jpeg|link=File:StolenS4-Pre-powder.jpeg|center|700px]]

Once again those purists out there will hate this thing but fuckem, its my bike and my wife bought it back for me and these are her favorite colors.

==Flywheel swap and a surprise 12/2025==
One of my favorite mods to these bikes is to ditch the flywheel. Lucky for me one popped up and I bought it. Pulling the stator cover off to install the flywheel, I was surprised to find and to remember the time I tossed a chain on this bike. It cracked the stator cover and luckily not the case.

[[File:Stolen4-statorcover.jpeg|link=File:Stolen4-statorcover.jpeg|center|700px]]

Here is the OE flywheel and my non-flywheel which is just big enough to hold the stator Mag and the starter bearing. While the flywheel mod makes the bike much more responsive, it can suffer around town at low revs, I don't love low revs so off it goes.

[[File:Stolen4-flywheels.jpeg|link=File:Stolen4-flywheels.jpeg|center|700px]]

Installed, you can hardly see the flywheel now.

[[File:Stolen4-flywheel-install.jpeg|link=File:Stolen4-flywheel-install.jpeg|center|700px]]

After years of use and storage, these motors get pretty nasty and cleaning them up is a PITA. After plugging all the holes, you drag them outside, spray them down with degrees a few times, scrape and brush, then power wash the hell out of them.

Next up is sanding, masking and painting.

==Back From Powder 12/2025==
It is always the best time when you get your parts back from being coated. All was well but there was an issue with the lower triple so that had to stay and be re-coated, which I will grab in the new year.

When I dropped the parts off I decided to go more teal than blue on this build and I am happy that I did. I think the Teal, Dark blue and Yellow will all play nicely with one another. My wife bought me this bike (but not all the parts and the rebuild!) so I think it is only suitable that the colors been in her color wheel.

[[File:StolenS4-Powder-Parts-4.jpeg|link=File:StolenS4-Powder-Parts-4.jpeg|center|700px]]

Two things I really dislike on bikes are the colors black and chrome, because of this I coated all the aluminum parts and the headlight ring an aluminum like silver, here I wanted to see how the bucket and rim would play and I think it worked out nicely.

[[File:StolenS4-Powder-Parts-2.jpeg|link=File:StolenS4-Powder-Parts-2.jpeg|center|700px]]

Finally here is Ledger smiling ear to ear checking out his bike that we are building, he is excited because it holds two people..

==Body back from paint 02/2026==
After getting all the body work prepped, I was able to get them to Sean ad SR customs to take it away. On the color front I went a little wild and chose colors my wife would like, in fact we copied a shampoo company who's colors we liked.

I had to toss the yellow in there, I wanted a little flare on this bike on top of the loud colors, this brought the coating of the calipers and suspension link, live a little I say.

This is also the first time I have ever used the 60' Ducati livery, I don't know why this time but thought it would play well with the roundness of the Monster tank. I do love the ducati double lines of the 70s but sometimes you need to do something new..

'''First thing to know is that this bike is not going to have a black seat (brown), just have the seat here to place parts on parts!'''

As you can see, I wanted to have some fun with the front fender, hoping it plays out!

==Wheels and tires 02/2026==

I flipped back and fourth on the wheels for this bike, mainly because I assumed I could not make the 1098 radials clear the spokes. Before trying I bought 749 wheels and assumed that was my route. For the hell of it I tried the wire wheels and the radials and as you have seen posted above, they did in fact work!

One of my other favorite things Ducati has ever done was to introduce the Sport Classic line with Aluminum rimmed spoked wheels of a normal, modern street bike tire size. 20 years ago I bought two sets of these, one went on the Monster and other to storage. The monster wheels showed signs of age and salty air on the spokes. The second were brand new but have some tarnish on the clear I hope to clean up. I decided to go with the NOS units I had and wrapped them with killer Pirelli's. Is there anything better than a SBK tire on a wire wheel set? I don't think so.

[[File:StolenS4-Body-wheels.jpeg|link=File:StolenS4-Body-wheels.jpeg|center|700px]]

==Engine Mask and paint 02/2026==
Once again, a purist would break down these engines, sandblast and repaint. I opted to clean, sand and re-paint as it gives great results with a lot less time spent on an fine running motor.

Masking is a labor of love but one that you must take your time on. Remember I had to replace the side cover from the previous chain loss, this motor was all silver (as all were in this year) but the cover I used was from an earlier motor which still used the green color.

==Rolled out to see the light of day 03/2026==

With me running off for a few weeks for springbreak, I took the opertunity to get the bike rolling and activated the front braking system so that I can safely transport the bike to the Silas at Revenant Auto to fabricate the exhaust system for the bike.

It was very nice to see the bike in the daylight allbeit without all the ugly parts on it (airbox, wiring, radiator and cooling). Excuse the orange tow straps on the fork, this was just before loading to go.

==There is a story behind every bike I own 12/2024==

Warning, 17mile story ahead.

Long long ago when I was building the 888LTD for Wally, there was a need for a set of 5spoke Marchesini wheels which many know are impossible to find for the 851/888 platform. My solution at the time was to find an S4 and buy it for the wheels which we did. I found a decent bike in upstate NY and drove out and paid cash for it (well, wally paid cash for it). The bike was your base model Monster S4, all stock, red, a good bike.

After stealing the wheels I was left wondering what fun could be had with a monster when left to my own devices and I think we found the way. I sourced a set of Sport classic wire wheels and a handful of other bits and started to goto work on the bike. The first thing to do was to paint the red away which I did with BMW's laguna sec blue (the same color as my race bikes at the time), then was the wheel swap, slipper clutch, power commander, clip ons and a saw to the exhaust.

The result was awesome: A loud, fun little run around with a decent amount of power. One of the biggest challanges was getting the gold line brakes to clear the spokes on the wire wheels (remember Ducati's solution to this was to use smaller, less brakes which I was having none of). My solution was to mill down the calipers until they cleared, the risk was blowing into the backs of the calipers and making a mess of my mill (this never happened luckly!)

The bike was totally stock when purchased, here it is in the back of the truck on its way to my shop in 2007

[[File:SSPX0048.jpg|link=File:SSPX0048.jpg|center|700px]]

I quickly took the bike apart, installed clip-ons, chopped the pipes, added wire wheels and a few other things

[[File:Monster3.jpg|link=File:Monster3.jpg|center|700px]]

I then painted the bike BMW Laguna Seca Blue which was my favorite. Here was the bike in 2008 when it was in my possession still

[[File:StolenS4-FrontRight.jpg|link=File:StolenS4-FrontRight.jpg|center|700px]]

[[File:StolenS4-Front.jpg|link=File:StolenS4-Front.jpg|center|700px]]

Here you can see my mill work on the calipers to get them to clear the spokes. I know, Im nuts!

[[File:StolenS4-Caliper.jpg|link=File:StolenS4-Caliper.jpg|center|700px]]

At the time I lived with a very close friend who I trusted and who didn't have a bike. I offered the bike to him to use and was foolish enough to give him the title and let him register the bike, which he did. A time later he and I had a big falling out where I offered for him to keep the bike, only to be told "Fuck you and your bike, I don't want it". A few weeks later he moved out and the bike left with him which surprised me, after all "fuck me and my bike" right? Well, I tried for 6 or 7 years to get the bike back and was repeatedly told I could buy the bike back which I refused to do.

Time went on and the guy sold or gave the bike to a fellow, who sold or gave the bike to another fellow. Rumors of the bike being for sale floated around and I even tossed a number out there for the bike but it was far too high for what I knew the bike was worth, so I passed. My friend Rocket got a call from the guy who had the bike and was offered the thing at more than half what I was offered it (this happens to me a lot) and Rocket called me to get the bike. I was so pissed about the number that I told him to shove it (so that he would tell the guy who had it to shove it) and that was the end of it. So I thought.

==So there I was, a week before Christmas 12/2024==

Working around the house, doing shit. Im talking to my wife and I hear this noise, a noise that is hard not to recognize, and my wife's smile which is a "I got you" smile. I start laughing and walk out to find Rocket in the driveway, sitting on the S4 in 20degree wheather freezing his ass off but cracking up! She had bought me the bike! Her words were: "Now the collection is all back together". My wife is the shit but little did she know that this move was going to cost me a ton of cash!

Here she is when it was returned to me. The Black livery is questionable, the clip-ons have been removed and a lot of other bits had been changed but overall she was still the bike I had last seen her as.

[[File:Stolen-S4-first-delivered.jpeg|link=File:Stolen-S4-first-delivered.jpeg|center|700px]]

==The buying spree begins 1/2025==

Because I know this bike so well and also know the platform in and out, before even riding this bike I did two things:
*Registered it
*Sourced most of the hard to find parts before taking it apart

The first challenge was a known one. The RI title I had last seen for this bike had a typo where an I was written as a 1 (common in RI long ago). The previous fellow decided to register it in Vermont and not deal with this. I went to the DMV, played dumb and had them check pictures of the stampings and fix the incorrect VIN.

As for sourcing parts, I went a bit haywire (shocker right). I decided go big or don't do it:
*Ohlins SBK fork with Radial bottoms (1198)
*Brembo 1198 radial calipers
*Brembo Radial master clutch and slave
*Speedymoto Monster to SBK triples
*Helibar clipons with a slight rise
*Termi spaghetti system with high mount Ti cans (Japan sourced, I have never seen these in the States, ever)
*Termi Monster 1100S cans, to be modded to fit the spaghetti systems while retaining the two up riding ability.
*Ohlins rear shock from an ST4s

The bummer about all this is the loss of the wire wheels. One of my favorite parts of this build is a monster with SC wheels but if I want radial brakes, the wheels must go, so they go because I like my brakes more than I like spoked wheels!

==Teardown and playing 10/2025==
With this bike, I didn't need to get her running, she is a runner. Right into the teardown and with it starts the mockup.

Here she is up on the lift, still basically a bike

[[File:Stolen4-teardown-1.jpeg|link=File:Stolen4-teardown-1.jpeg|center|700px]]

A little more extreme breakdown:

[[File:Stolen4-teardown-2.jpeg|link=File:Stolen4-teardown-2.jpeg|center|700px]]

This teardown will be jumping between teardown and mockup so unlike many of my other builds, this bike will look a lot more together throughout its evolution.

==Frontend build and mockup 10/2025==
For this bike I thought the 1098 / 1199 Ohlins with radials would look cool (and ride fucking awesome), the old FG43 bottoms are rad and all but really stand for the 90s and early 2000s. With the monster and all its swooping curves, the interegal radials will have a good look with the rest of the bike (I hope), additionally the final OG monster (S4RS) had radial bottoms but where a non SBK fork.

Here you can see them being serviced at Superbike services44 in New Hampshire. It always cracks me up to see the cost savings for ohlins when they only plate in gold the bits you see and not the others

[[File:Stolen4-tubes.jpeg|link=File:Stolen4-tubes.jpeg|center|700px]]

How many licks does it take to get to the center of a tootsie pop? The same can be said as to how many parts make up a front fork.

[[File:Stolen4-internals.jpeg|link=File:Stolen4-internals.jpeg|center|700px]]

When it came time to figure out the front end on this bike I was laser focused on an S4RS full front end but they were hard to find and not as good. I then remembered I had this fork in a pile but that it would require unique triples, lucky for me speedy moto dealt with this long ago and made a tripe for it. Im not a huge fan of the black anodizing but it is all I could get! Powder coating will resolve the black issue.

[[File:Stolen4-triples.jpeg|link=File:Stolen4-triples.jpeg|center|700px]]

For clipons, I went with a set of Helibars that came to me in a bulk buy. They are NOS and give me almost an inch up which should be good for 2up riding which this bike will be used for. I am also toying with wire wheels or 999 wheels, here you can see the 999 option.

[[File:Stolen4-front-test-1.jpeg|link=SFile:tolen4-front-test-1.jpeg|center|700px]]

It is always funny to see a bike with no headlight and no fairing, everything looks wrong.

Next up I have to figure out the wheel situation. Running a 999 rear in the ST / S4 swingarm is going to be challenging and at the the same time running a wire wheel in the 1098 fork has brake clearance challenges. More to come there in the coming weeks. My pref is wire but they are heavier. I don't know..

==Driveline Mockup 10/2025==
My plan was to run 749/999 wheels on this bike to allow for radial from calipers but much to my delight, the SC wire wheel spokes JUST clear the calipers, I will be milling them a tad just to allow for some more room.

Sticking with the wire wheels on this build makes me very happy, for some reason I have always loved the look of the SC aluminum hub / rim wheels along with road tires (which are not what are on these wheels right now). I have another set of wheels that are un-used that will be getting a set of road tires mounted in the coming weeks.

Monsters look funny without the big ass rearsets installed as you can see. I was thinking about doing away with them for the aesthetic but I want this bike to be good for two up riding so they will be sticking around.

[[File:Stolen4-driveline-mock-1.jpeg|link=File:Stolen4-driveline-mock-1.jpeg|center|700px]]

The ST4S rear shock mounted well and the rez plumbing clears the frame the way I had hoped. Here you see the rebound adjuster
[[File:Stolen4-driveline-mock-2.jpeg|link=File:Stolen4-driveline-mock-2.jpeg|center|700px]]

On the other side you see the compression adjust / rez with the line fitting well in the frame.
[[File:Stolen4-driveline-mock-3.jpeg|link=File:Stolen4-driveline-mock-3.jpeg|center|700px]]

Im testing the OG cast iron floating rotors on one side to see how the clearance is, which is perfect. For some reason I love these Tron looking rotors and am happy to have a bike I can run them on (6 bolt with the correct offset), all my other bikes are so modified I had to go other directions.
[[File:Stolen4-driveline-mock-4.jpeg|link=File:Stolen4-driveline-mock-4.jpeg|center|700px]]
==Body work planning 11/2025==
Talking about bodywork on a monster is the wrong way to put it but I had to come up with something. Those that know the monster know it's entire market is based on the lack of bodywork but here we will talk about the three major parts:
Tank: Monster S4RS
Front fender: Monster 1100S
Seat cowl: Monster S2R

To start I always like to switch it up with the front fenders on these builds so after poking around, I settled on a very modern looking 1100S monster fender, My fingers are crossed here. The Tank is from an S4RS so it is plastic and has a modern internal, removable pickup / pump unit and the cowl is a standard monster unit which I have always had a thing for.

The plan is to have a deep blue base, with a frame matching green center section on all three items, the line on the tank will only goto the fuel fill cap. The Ducati name will come from yellow late 60s ducati stickers.

[[File:StolenS4-Body-pre-paint.jpeg|link=File:StolenS4-Body-pre-paint.jpeg|center|700px]]
==Brake mod to clear the spokes==
The wire wheels on from the Sport Classic are very well built and therefore the spokes come off the very wide hub to get to the Rim, this made clearance a problem from the beginning. Ducati's solution was to use smaller, less good brake calipers which cleared the spokes and used an adapter. On my first go around I milled the calipers to clear the spokes which was required and which gave me proper braking at the time.

This time I was rather surprised to see that the SBK 100MM radial calipers "mostly" cleared the spokes, which the goldline calipers didn't at all. Regardless, I wanted more clearance incase a rock or a piece of a car gets in there, I don't want it to stop the from wheel.

Here you can see the caliper before being milled:

[[File:StolenS4-Caliper-pre.jpeg|link=File:StolenS4-Caliper-pre.jpeg |center|700px]]

And after being milled:

[[File:StolenS4-Caliper-post.jpeg|link=File:StolenS4-Caliper-post.jpeg |center|700px]]

These will be powder coated bright yellow which I am excited to see.

==Parts off to Powder 11/2025==
I have always loved taking this picture but I love taking the picture of the parts once they are returned far more.

We will have a a aqua frame and light bucket while having a aluminum silver swingarm, triples, clipons, rearset frames and highlight surround. We will also have yellow suspension link and calipers all around.

[[File:StolenS4-Pre-powder.jpeg|link=File:StolenS4-Pre-powder.jpeg|center|700px]]

Once again those purists out there will hate this thing but fuckem, its my bike and my wife bought it back for me and these are her favorite colors.

==Flywheel swap and a surprise 12/2025==
One of my favorite mods to these bikes is to ditch the flywheel. Lucky for me one popped up and I bought it. Pulling the stator cover off to install the flywheel, I was surprised to find and to remember the time I tossed a chain on this bike. It cracked the stator cover and luckily not the case.

[[File:Stolen4-statorcover.jpeg|link=File:Stolen4-statorcover.jpeg|center|700px]]

Here is the OE flywheel and my non-flywheel which is just big enough to hold the stator Mag and the starter bearing. While the flywheel mod makes the bike much more responsive, it can suffer around town at low revs, I don't love low revs so off it goes.

[[File:Stolen4-flywheels.jpeg|link=File:Stolen4-flywheels.jpeg|center|700px]]

Installed, you can hardly see the flywheel now.

Prepping the replacement stator cover, next to original unit to the right.

[[File:Stolen4-statorcovers.jpeg|link=File:Stolen4-statorcovers.jpeg|center|700px]]

==Engine Degrease 12/2025==
After years of use and storage, these motors get pretty nasty and cleaning them up is a PITA. After plugging all the holes, you drag them outside, spray them down with degrees a few times, scrape and brush, then power wash the hell out of them.

==Body back from paint 02/2026==
After getting all the body work prepped, I was able to get them to Sean ad SR customs to take it away. On the color front I went a little wild and chose colors my wife would like, in fact we copied a shampoo company who's colors we liked.

I had to toss the yellow in there, I wanted a little flare on this bike on top of the loud colors, this brought the coating of the calipers and suspension link, live a little I say.

This is also the first time I have ever used the 60' Ducati livery, I don't know why this time but thought it would play well with the roundness of the Monster tank. I do love the ducati double lines of the 70s but sometimes you need to do something new..

During the worst winter in 50 years in Rhode Island, it took weeks to get a window of time where I could paint where the temp was warm enough for the paint. Primer is laid down first, followed by color.

With me running off for a few weeks for springbreak, I took the opertunity to get the bike rolling and activated the front braking system so that I can safely transport the bike to the Silas at Revenant Auto to fabricate the exhaust system for the bike.

It was very nice to see the bike in the daylight allbeit without all the ugly parts on it (airbox, wiring, radiator and cooling). Excuse the orange tow straps on the fork, this was just before loading to go.

==There is a story behind every bike I own 12/2024==

Warning, 17mile story ahead.

Long long ago when I was building the 888LTD for Wally, there was a need for a set of 5spoke Marchesini wheels which many know are impossible to find for the 851/888 platform. My solution at the time was to find an S4 and buy it for the wheels which we did. I found a decent bike in upstate NY and drove out and paid cash for it (well, wally paid cash for it). The bike was your base model Monster S4, all stock, red, a good bike.

After stealing the wheels I was left wondering what fun could be had with a monster when left to my own devices and I think we found the way. I sourced a set of Sport classic wire wheels and a handful of other bits and started to goto work on the bike. The first thing to do was to paint the red away which I did with BMW's laguna sec blue (the same color as my race bikes at the time), then was the wheel swap, slipper clutch, power commander, clip ons and a saw to the exhaust.

The result was awesome: A loud, fun little run around with a decent amount of power. One of the biggest challanges was getting the gold line brakes to clear the spokes on the wire wheels (remember Ducati's solution to this was to use smaller, less brakes which I was having none of). My solution was to mill down the calipers until they cleared, the risk was blowing into the backs of the calipers and making a mess of my mill (this never happened luckly!)

The bike was totally stock when purchased, here it is in the back of the truck on its way to my shop in 2007

[[File:SSPX0048.jpg|link=File:SSPX0048.jpg|center|700px]]

I quickly took the bike apart, installed clip-ons, chopped the pipes, added wire wheels and a few other things

[[File:Monster3.jpg|link=File:Monster3.jpg|center|700px]]

I then painted the bike BMW Laguna Seca Blue which was my favorite. Here was the bike in 2008 when it was in my possession still

[[File:StolenS4-FrontRight.jpg|link=File:StolenS4-FrontRight.jpg|center|700px]]

[[File:StolenS4-Front.jpg|link=File:StolenS4-Front.jpg|center|700px]]

Here you can see my mill work on the calipers to get them to clear the spokes. I know, Im nuts!

[[File:StolenS4-Caliper.jpg|link=File:StolenS4-Caliper.jpg|center|700px]]

At the time I lived with a very close friend who I trusted and who didn't have a bike. I offered the bike to him to use and was foolish enough to give him the title and let him register the bike, which he did. A time later he and I had a big falling out where I offered for him to keep the bike, only to be told "Fuck you and your bike, I don't want it". A few weeks later he moved out and the bike left with him which surprised me, after all "fuck me and my bike" right? Well, I tried for 6 or 7 years to get the bike back and was repeatedly told I could buy the bike back which I refused to do.

Time went on and the guy sold or gave the bike to a fellow, who sold or gave the bike to another fellow. Rumors of the bike being for sale floated around and I even tossed a number out there for the bike but it was far too high for what I knew the bike was worth, so I passed. My friend Rocket got a call from the guy who had the bike and was offered the thing at more than half what I was offered it (this happens to me a lot) and Rocket called me to get the bike. I was so pissed about the number that I told him to shove it (so that he would tell the guy who had it to shove it) and that was the end of it. So I thought.

==So there I was, a week before Christmas 12/2024==

Working around the house, doing shit. Im talking to my wife and I hear this noise, a noise that is hard not to recognize, and my wife's smile which is a "I got you" smile. I start laughing and walk out to find Rocket in the driveway, sitting on the S4 in 20degree wheather freezing his ass off but cracking up! She had bought me the bike! Her words were: "Now the collection is all back together". My wife is the shit but little did she know that this move was going to cost me a ton of cash!

Here she is when it was returned to me. The Black livery is questionable, the clip-ons have been removed and a lot of other bits had been changed but overall she was still the bike I had last seen her as.

[[File:Stolen-S4-first-delivered.jpeg|link=File:Stolen-S4-first-delivered.jpeg|center|700px]]

==The buying spree begins 1/2025==

Because I know this bike so well and also know the platform in and out, before even riding this bike I did two things:
*Registered it
*Sourced most of the hard to find parts before taking it apart

The first challenge was a known one. The RI title I had last seen for this bike had a typo where an I was written as a 1 (common in RI long ago). The previous fellow decided to register it in Vermont and not deal with this. I went to the DMV, played dumb and had them check pictures of the stampings and fix the incorrect VIN.

As for sourcing parts, I went a bit haywire (shocker right). I decided go big or don't do it:
*Ohlins SBK fork with Radial bottoms (1198)
*Brembo 1198 radial calipers
*Brembo Radial master clutch and slave
*Speedymoto Monster to SBK triples
*Helibar clipons with a slight rise
*Termi spaghetti system with high mount Ti cans (Japan sourced, I have never seen these in the States, ever)
*Termi Monster 1100S cans, to be modded to fit the spaghetti systems while retaining the two up riding ability.
*Ohlins rear shock from an ST4s

The bummer about all this is the loss of the wire wheels. One of my favorite parts of this build is a monster with SC wheels but if I want radial brakes, the wheels must go, so they go because I like my brakes more than I like spoked wheels!

==Teardown and playing 10/2025==
With this bike, I didn't need to get her running, she is a runner. Right into the teardown and with it starts the mockup.

Here she is up on the lift, still basically a bike

[[File:Stolen4-teardown-1.jpeg|link=File:Stolen4-teardown-1.jpeg|center|700px]]

A little more extreme breakdown:

[[File:Stolen4-teardown-2.jpeg|link=File:Stolen4-teardown-2.jpeg|center|700px]]

This teardown will be jumping between teardown and mockup so unlike many of my other builds, this bike will look a lot more together throughout its evolution.

==Frontend build and mockup 10/2025==
For this bike I thought the 1098 / 1199 Ohlins with radials would look cool (and ride fucking awesome), the old FG43 bottoms are rad and all but really stand for the 90s and early 2000s. With the monster and all its swooping curves, the interegal radials will have a good look with the rest of the bike (I hope), additionally the final OG monster (S4RS) had radial bottoms but where a non SBK fork.

Here you can see them being serviced at Superbike services44 in New Hampshire. It always cracks me up to see the cost savings for ohlins when they only plate in gold the bits you see and not the others

[[File:Stolen4-tubes.jpeg|link=File:Stolen4-tubes.jpeg|center|700px]]

How many licks does it take to get to the center of a tootsie pop? The same can be said as to how many parts make up a front fork.

[[File:Stolen4-internals.jpeg|link=File:Stolen4-internals.jpeg|center|700px]]

When it came time to figure out the front end on this bike I was laser focused on an S4RS full front end but they were hard to find and not as good. I then remembered I had this fork in a pile but that it would require unique triples, lucky for me speedy moto dealt with this long ago and made a tripe for it. Im not a huge fan of the black anodizing but it is all I could get! Powder coating will resolve the black issue.

[[File:Stolen4-triples.jpeg|link=File:Stolen4-triples.jpeg|center|700px]]

For clipons, I went with a set of Helibars that came to me in a bulk buy. They are NOS and give me almost an inch up which should be good for 2up riding which this bike will be used for. I am also toying with wire wheels or 999 wheels, here you can see the 999 option.

[[File:Stolen4-front-test-1.jpeg|link=SFile:tolen4-front-test-1.jpeg|center|700px]]

It is always funny to see a bike with no headlight and no fairing, everything looks wrong.

Next up I have to figure out the wheel situation. Running a 999 rear in the ST / S4 swingarm is going to be challenging and at the the same time running a wire wheel in the 1098 fork has brake clearance challenges. More to come there in the coming weeks. My pref is wire but they are heavier. I don't know..

==Driveline Mockup 10/2025==
My plan was to run 749/999 wheels on this bike to allow for radial from calipers but much to my delight, the SC wire wheel spokes JUST clear the calipers, I will be milling them a tad just to allow for some more room.

Sticking with the wire wheels on this build makes me very happy, for some reason I have always loved the look of the SC aluminum hub / rim wheels along with road tires (which are not what are on these wheels right now). I have another set of wheels that are un-used that will be getting a set of road tires mounted in the coming weeks.

Monsters look funny without the big ass rearsets installed as you can see. I was thinking about doing away with them for the aesthetic but I want this bike to be good for two up riding so they will be sticking around.

[[File:Stolen4-driveline-mock-1.jpeg|link=File:Stolen4-driveline-mock-1.jpeg|center|700px]]

The ST4S rear shock mounted well and the rez plumbing clears the frame the way I had hoped. Here you see the rebound adjuster
[[File:Stolen4-driveline-mock-2.jpeg|link=File:Stolen4-driveline-mock-2.jpeg|center|700px]]

On the other side you see the compression adjust / rez with the line fitting well in the frame.
[[File:Stolen4-driveline-mock-3.jpeg|link=File:Stolen4-driveline-mock-3.jpeg|center|700px]]

Im testing the OG cast iron floating rotors on one side to see how the clearance is, which is perfect. For some reason I love these Tron looking rotors and am happy to have a bike I can run them on (6 bolt with the correct offset), all my other bikes are so modified I had to go other directions.
[[File:Stolen4-driveline-mock-4.jpeg|link=File:Stolen4-driveline-mock-4.jpeg|center|700px]]
==Body work planning 11/2025==
Talking about bodywork on a monster is the wrong way to put it but I had to come up with something. Those that know the monster know it's entire market is based on the lack of bodywork but here we will talk about the three major parts:
Tank: Monster S4RS
Front fender: Monster 1100S
Seat cowl: Monster S2R

To start I always like to switch it up with the front fenders on these builds so after poking around, I settled on a very modern looking 1100S monster fender, My fingers are crossed here. The Tank is from an S4RS so it is plastic and has a modern internal, removable pickup / pump unit and the cowl is a standard monster unit which I have always had a thing for.

The plan is to have a deep blue base, with a frame matching green center section on all three items, the line on the tank will only goto the fuel fill cap. The Ducati name will come from yellow late 60s ducati stickers.

[[File:StolenS4-Body-pre-paint.jpeg|link=File:StolenS4-Body-pre-paint.jpeg|center|700px]]
==Brake mod to clear the spokes==
The wire wheels on from the Sport Classic are very well built and therefore the spokes come off the very wide hub to get to the Rim, this made clearance a problem from the beginning. Ducati's solution was to use smaller, less good brake calipers which cleared the spokes and used an adapter. On my first go around I milled the calipers to clear the spokes which was required and which gave me proper braking at the time.

This time I was rather surprised to see that the SBK 100MM radial calipers "mostly" cleared the spokes, which the goldline calipers didn't at all. Regardless, I wanted more clearance incase a rock or a piece of a car gets in there, I don't want it to stop the from wheel.

Here you can see the caliper before being milled:

[[File:StolenS4-Caliper-pre.jpeg|link=File:StolenS4-Caliper-pre.jpeg |center|700px]]

And after being milled:

[[File:StolenS4-Caliper-post.jpeg|link=File:StolenS4-Caliper-post.jpeg |center|700px]]

These will be powder coated bright yellow which I am excited to see.

==Parts off to Powder 11/2025==
I have always loved taking this picture but I love taking the picture of the parts once they are returned far more.

We will have a a aqua frame and light bucket while having a aluminum silver swingarm, triples, clipons, rearset frames and highlight surround. We will also have yellow suspension link and calipers all around.

[[File:StolenS4-Pre-powder.jpeg|link=File:StolenS4-Pre-powder.jpeg|center|700px]]

Once again those purists out there will hate this thing but fuckem, its my bike and my wife bought it back for me and these are her favorite colors.

==Flywheel swap and a surprise 12/2025==
One of my favorite mods to these bikes is to ditch the flywheel. Lucky for me one popped up and I bought it. Pulling the stator cover off to install the flywheel, I was surprised to find and to remember the time I tossed a chain on this bike. It cracked the stator cover and luckily not the case.

[[File:Stolen4-statorcover.jpeg|link=File:Stolen4-statorcover.jpeg|center|700px]]

Here is the OE flywheel and my non-flywheel which is just big enough to hold the stator Mag and the starter bearing. While the flywheel mod makes the bike much more responsive, it can suffer around town at low revs, I don't love low revs so off it goes.

[[File:Stolen4-flywheels.jpeg|link=File:Stolen4-flywheels.jpeg|center|700px]]

Installed, you can hardly see the flywheel now.

[[File:Stolen4-flywheel-install.jpeg|link=File:Stolen4-flywheel-install.jpeg|center|700px]]

Prepping the replacement stator cover, next to original unit to the right.

[[File:Stolen4-statorcovers.jpeg|link=File:Stolen4-statorcovers.jpeg|center|700px]]

==Engine Degrease 12/2025==
After years of use and storage, these motors get pretty nasty and cleaning them up is a PITA. After plugging all the holes, you drag them outside, spray them down with degrees a few times, scrape and brush, then power wash the hell out of them.

Before starting:
[[File:Stolen4-engine-dirty-1.jpeg|link=File:Stolen4-engine-dirty-1.jpeg|center|700px]]

[[File:Stolen4-engine-dirty-2.jpeg|link=File:Stolen4-engine-dirty-2.jpeg|center|700px]]

After a lot of scrubbing and spraying and scrubbing and spraying:

[[File:Stolen4-engine-clean-1.jpeg|link=File:Stolen4-engine-clean-1.jpeg|center|700px]]

[[File:Stolen4-engine-clean-2.jpeg|link=File:Stolen4-engine-clean-2.jpeg|center|700px]]

[[File:Stolen4-engine-clean-3.jpeg|link=File:Stolen4-engine-clean-3.jpeg|center|700px]]

Next up is sanding, masking and painting.

==Back From Powder 12/2025==
It is always the best time when you get your parts back from being coated. All was well but there was an issue with the lower triple so that had to stay and be re-coated, which I will grab in the new year.

When I dropped the parts off I decided to go more teal than blue on this build and I am happy that I did. I think the Teal, Dark blue and Yellow will all play nicely with one another. My wife bought me this bike (but not all the parts and the rebuild!) so I think it is only suitable that the colors been in her color wheel.

[[File:StolenS4-Powder-Parts-1.jpeg|link=File:StolenS4-Powder-Parts-1.jpeg|center|700px]]

[[File:StolenS4-Powder-Parts-4.jpeg|link=File:StolenS4-Powder-Parts-4.jpeg|center|700px]]

Two things I really dislike on bikes are the colors black and chrome, because of this I coated all the aluminum parts and the headlight ring an aluminum like silver, here I wanted to see how the bucket and rim would play and I think it worked out nicely.

[[File:StolenS4-Powder-Parts-2.jpeg|link=File:StolenS4-Powder-Parts-2.jpeg|center|700px]]

Finally here is Ledger smiling ear to ear checking out his bike that we are building, he is excited because it holds two people..

[[File:StolenS4-Powder-Parts-3.jpeg|link=File:StolenS4-Powder-Parts-3.jpeg|center|700px]]

==Body back from paint 02/2026==
After getting all the body work prepped, I was able to get them to Sean ad SR customs to take it away. On the color front I went a little wild and chose colors my wife would like, in fact we copied a shampoo company who's colors we liked.

I had to toss the yellow in there, I wanted a little flare on this bike on top of the loud colors, this brought the coating of the calipers and suspension link, live a little I say.

This is also the first time I have ever used the 60' Ducati livery, I don't know why this time but thought it would play well with the roundness of the Monster tank. I do love the ducati double lines of the 70s but sometimes you need to do something new..

'''First thing to know is that this bike is not going to have a black seat (brown), just have the seat here to place parts on parts!'''

[[File:StolenS4-Body-left.jpeg|link=File:StolenS4-Body-left.jpeg|center|700px]]

Lots ohh parts!
[[File:StolenS4-Body-front.jpeg|link=File:StolenS4-Body-front.jpeg|center|700px]]

As you can see, I wanted to have some fun with the front fender, hoping it plays out!
[[File:StolenS4-Body-right.jpeg|link=File:StolenS4-Body-right.jpeg|center|700px]]

Wings and things...
[[File:StolenS4-Body-tank-right.jpeg|link=File:StolenS4-Body-tank-right.jpeg|center|700px]]

The monster tail will always be one of my favorite pieces of body work every to leave Bologna. Yuck to that seat!
[[File:StolenS4-Body-tail.jpeg|link=File:StolenS4-Body-tail.jpeg|center|700px]]

Finally you can see Sean's ability to match paint to powder. Very impressive.
[[File:StolenS4-Body-front-left.jpeg|link=File:StolenS4-Body-front-left.jpeg|center|700px]]

==Wheels and tires 02/2026==

I flipped back and fourth on the wheels for this bike, mainly because I assumed I could not make the 1098 radials clear the spokes. Before trying I bought 749 wheels and assumed that was my route. For the hell of it I tried the wire wheels and the radials and as you have seen posted above, they did in fact work!

One of my other favorite things Ducati has ever done was to introduce the Sport Classic line with Aluminum rimmed spoked wheels of a normal, modern street bike tire size. 20 years ago I bought two sets of these, one went on the Monster and other to storage. The monster wheels showed signs of age and salty air on the spokes. The second were brand new but have some tarnish on the clear I hope to clean up. I decided to go with the NOS units I had and wrapped them with killer Pirelli's. Is there anything better than a SBK tire on a wire wheel set? I don't think so.

[[File:StolenS4-Body-wheels.jpeg|link=File:StolenS4-Body-wheels.jpeg|center|700px]]

==Engine Mask and paint 02/2026==
Once again, a purist would break down these engines, sandblast and repaint. I opted to clean, sand and re-paint as it gives great results with a lot less time spent on an fine running motor.

Masking is a labor of love but one that you must take your time on. Remember I had to replace the side cover from the previous chain loss, this motor was all silver (as all were in this year) but the cover I used was from an earlier motor which still used the green color.

[[File:Stolen4-engine-mask1.jpeg|link=File:Stolen4-engine-mask1.jpeg|center|700px]]

==Initial Build 02/2026==

==Rolled out to see the light of day 03/2026==

With me running off for a few weeks for springbreak, I took the opertunity to get the bike rolling and activated the front braking system so that I can safely transport the bike to the Silas at Revenant Auto to fabricate the exhaust system for the bike.

It was very nice to see the bike in the daylight allbeit without all the ugly parts on it (airbox, wiring, radiator and cooling). Excuse the orange tow straps on the fork, this was just before loading to go.

I was so pissed about the number that I told him to shove it (so that he would tell the guy who had it to shove it) and that was the end of it. So I thought.

==So there I was, a week before Christmas 12/2024==

Working around the house, doing shit. Im talking to my wife and I hear this noise, a noise that is hard not to recognize, and my wife's smile which is a "I got you" smile. I start laughing and walk out to find Rocket in the driveway, sitting on the S4 in 20degree wheather freezing his ass off but cracking up! She had bought me the bike! Her words were: "Now the collection is all back together". My wife is the shit but little did she know that this move was going to cost me a ton of cash!

Here she is when it was returned to me. The Black livery is questionable, the clip-ons have been removed and a lot of other bits had been changed but overall she was still the bike I had last seen her as.

[[File:Stolen-S4-first-delivered.jpeg|link=File:Stolen-S4-first-delivered.jpeg|center|700px]]

==The buying spree begins 1/2025==

Because I know this bike so well and also know the platform in and out, before even riding this bike I did two things:
*Registered it
*Sourced most of the hard to find parts before taking it apart

The first challenge was a known one. The RI title I had last seen for this bike had a typo where an I was written as a 1 (common in RI long ago). The previous fellow decided to register it in Vermont and not deal with this. I went to the DMV, played dumb and had them check pictures of the stampings and fix the incorrect VIN.

As for sourcing parts, I went a bit haywire (shocker right). I decided go big or don't do it:
*Ohlins SBK fork with Radial bottoms (1198)
*Brembo 1198 radial calipers
*Brembo Radial master clutch and slave
*Speedymoto Monster to SBK triples
*Helibar clipons with a slight rise
*Termi spaghetti system with high mount Ti cans (Japan sourced, I have never seen these in the States, ever)
*Termi Monster 1100S cans, to be modded to fit the spaghetti systems while retaining the two up riding ability.
*Ohlins rear shock from an ST4s

The bummer about all this is the loss of the wire wheels. One of my favorite parts of this build is a monster with SC wheels but if I want radial brakes, the wheels must go, so they go because I like my brakes more than I like spoked wheels!

==Teardown and playing 10/2025==
With this bike, I didn't need to get her running, she is a runner. Right into the teardown and with it starts the mockup.

Here she is up on the lift, still basically a bike

[[File:Stolen4-teardown-1.jpeg|link=File:Stolen4-teardown-1.jpeg|center|700px]]

A little more extreme breakdown:

[[File:Stolen4-teardown-2.jpeg|link=File:Stolen4-teardown-2.jpeg|center|700px]]

This teardown will be jumping between teardown and mockup so unlike many of my other builds, this bike will look a lot more together throughout its evolution.

==Frontend build and mockup 10/2025==
For this bike I thought the 1098 / 1199 Ohlins with radials would look cool (and ride fucking awesome), the old FG43 bottoms are rad and all but really stand for the 90s and early 2000s. With the monster and all its swooping curves, the interegal radials will have a good look with the rest of the bike (I hope), additionally the final OG monster (S4RS) had radial bottoms but where a non SBK fork.

Here you can see them being serviced at Superbike services44 in New Hampshire. It always cracks me up to see the cost savings for ohlins when they only plate in gold the bits you see and not the others

[[File:Stolen4-tubes.jpeg|link=File:Stolen4-tubes.jpeg|center|700px]]

How many licks does it take to get to the center of a tootsie pop? The same can be said as to how many parts make up a front fork.

[[File:Stolen4-internals.jpeg|link=File:Stolen4-internals.jpeg|center|700px]]

When it came time to figure out the front end on this bike I was laser focused on an S4RS full front end but they were hard to find and not as good. I then remembered I had this fork in a pile but that it would require unique triples, lucky for me speedy moto dealt with this long ago and made a tripe for it. Im not a huge fan of the black anodizing but it is all I could get! Powder coating will resolve the black issue.

[[File:Stolen4-triples.jpeg|link=File:Stolen4-triples.jpeg|center|700px]]

For clipons, I went with a set of Helibars that came to me in a bulk buy. They are NOS and give me almost an inch up which should be good for 2up riding which this bike will be used for. I am also toying with wire wheels or 999 wheels, here you can see the 999 option.

[[File:Stolen4-front-test-1.jpeg|link=SFile:tolen4-front-test-1.jpeg|center|700px]]

It is always funny to see a bike with no headlight and no fairing, everything looks wrong.

Next up I have to figure out the wheel situation. Running a 999 rear in the ST / S4 swingarm is going to be challenging and at the the same time running a wire wheel in the 1098 fork has brake clearance challenges. More to come there in the coming weeks. My pref is wire but they are heavier. I don't know..

==Driveline Mockup 10/2025==
My plan was to run 749/999 wheels on this bike to allow for radial from calipers but much to my delight, the SC wire wheel spokes JUST clear the calipers, I will be milling them a tad just to allow for some more room.

Sticking with the wire wheels on this build makes me very happy, for some reason I have always loved the look of the SC aluminum hub / rim wheels along with road tires (which are not what are on these wheels right now). I have another set of wheels that are un-used that will be getting a set of road tires mounted in the coming weeks.

Monsters look funny without the big ass rearsets installed as you can see. I was thinking about doing away with them for the aesthetic but I want this bike to be good for two up riding so they will be sticking around.

[[File:Stolen4-driveline-mock-1.jpeg|link=File:Stolen4-driveline-mock-1.jpeg|center|700px]]

The ST4S rear shock mounted well and the rez plumbing clears the frame the way I had hoped. Here you see the rebound adjuster
[[File:Stolen4-driveline-mock-2.jpeg|link=File:Stolen4-driveline-mock-2.jpeg|center|700px]]

On the other side you see the compression adjust / rez with the line fitting well in the frame.
[[File:Stolen4-driveline-mock-3.jpeg|link=File:Stolen4-driveline-mock-3.jpeg|center|700px]]

Im testing the OG cast iron floating rotors on one side to see how the clearance is, which is perfect. For some reason I love these Tron looking rotors and am happy to have a bike I can run them on (6 bolt with the correct offset), all my other bikes are so modified I had to go other directions.
[[File:Stolen4-driveline-mock-4.jpeg|link=File:Stolen4-driveline-mock-4.jpeg|center|700px]]
==Body work planning 11/2025==
Talking about bodywork on a monster is the wrong way to put it but I had to come up with something. Those that know the monster know it's entire market is based on the lack of bodywork but here we will talk about the three major parts:
Tank: Monster S4RS
Front fender: Monster 1100S
Seat cowl: Monster S2R

To start I always like to switch it up with the front fenders on these builds so after poking around, I settled on a very modern looking 1100S monster fender, My fingers are crossed here. The Tank is from an S4RS so it is plastic and has a modern internal, removable pickup / pump unit and the cowl is a standard monster unit which I have always had a thing for.

The plan is to have a deep blue base, with a frame matching green center section on all three items, the line on the tank will only goto the fuel fill cap. The Ducati name will come from yellow late 60s ducati stickers.

[[File:StolenS4-Body-pre-paint.jpeg|link=File:StolenS4-Body-pre-paint.jpeg|center|700px]]
==Brake mod to clear the spokes==
The wire wheels on from the Sport Classic are very well built and therefore the spokes come off the very wide hub to get to the Rim, this made clearance a problem from the beginning. Ducati's solution was to use smaller, less good brake calipers which cleared the spokes and used an adapter. On my first go around I milled the calipers to clear the spokes which was required and which gave me proper braking at the time.

This time I was rather surprised to see that the SBK 100MM radial calipers "mostly" cleared the spokes, which the goldline calipers didn't at all. Regardless, I wanted more clearance incase a rock or a piece of a car gets in there, I don't want it to stop the from wheel.

Here you can see the caliper before being milled:

[[File:StolenS4-Caliper-pre.jpeg|link=File:StolenS4-Caliper-pre.jpeg |center|700px]]

And after being milled:

[[File:StolenS4-Caliper-post.jpeg|link=File:StolenS4-Caliper-post.jpeg |center|700px]]

These will be powder coated bright yellow which I am excited to see.

==Parts off to Powder 11/2025==
I have always loved taking this picture but I love taking the picture of the parts once they are returned far more.

We will have a a aqua frame and light bucket while having a aluminum silver swingarm, triples, clipons, rearset frames and highlight surround. We will also have yellow suspension link and calipers all around.

[[File:StolenS4-Pre-powder.jpeg|link=File:StolenS4-Pre-powder.jpeg|center|700px]]

Once again those purists out there will hate this thing but fuckem, its my bike and my wife bought it back for me and these are her favorite colors.

==Flywheel swap and a surprise 12/2025==
One of my favorite mods to these bikes is to ditch the flywheel. Lucky for me one popped up and I bought it. Pulling the stator cover off to install the flywheel, I was surprised to find and to remember the time I tossed a chain on this bike. It cracked the stator cover and luckily not the case.

[[File:Stolen4-statorcover.jpeg|link=File:Stolen4-statorcover.jpeg|center|700px]]

Here is the OE flywheel and my non-flywheel which is just big enough to hold the stator Mag and the starter bearing. While the flywheel mod makes the bike much more responsive, it can suffer around town at low revs, I don't love low revs so off it goes.

[[File:Stolen4-flywheels.jpeg|link=File:Stolen4-flywheels.jpeg|center|700px]]

Installed, you can hardly see the flywheel now.

[[File:Stolen4-flywheel-install.jpeg|link=File:Stolen4-flywheel-install.jpeg|center|700px]]

Prepping the replacement stator cover, next to original unit to the right.

[[File:Stolen4-statorcovers.jpeg|link=File:Stolen4-statorcovers.jpeg|center|700px]]

==Engine Degrease 12/2025==
After years of use and storage, these motors get pretty nasty and cleaning them up is a PITA. After plugging all the holes, you drag them outside, spray them down with degrees a few times, scrape and brush, then power wash the hell out of them.

Before starting:
[[File:Stolen4-engine-dirty-1.jpeg|link=File:Stolen4-engine-dirty-1.jpeg|center|700px]]

[[File:Stolen4-engine-dirty-2.jpeg|link=File:Stolen4-engine-dirty-2.jpeg|center|700px]]

After a lot of scrubbing and spraying and scrubbing and spraying:

[[File:Stolen4-engine-clean-1.jpeg|link=File:Stolen4-engine-clean-1.jpeg|center|700px]]

[[File:Stolen4-engine-clean-2.jpeg|link=File:Stolen4-engine-clean-2.jpeg|center|700px]]

[[File:Stolen4-engine-clean-3.jpeg|link=File:Stolen4-engine-clean-3.jpeg|center|700px]]

Next up is sanding, masking and painting.

==Back From Powder 12/2025==
It is always the best time when you get your parts back from being coated. All was well but there was an issue with the lower triple so that had to stay and be re-coated, which I will grab in the new year.

When I dropped the parts off I decided to go more teal than blue on this build and I am happy that I did. I think the Teal, Dark blue and Yellow will all play nicely with one another. My wife bought me this bike (but not all the parts and the rebuild!) so I think it is only suitable that the colors been in her color wheel.

[[File:StolenS4-Powder-Parts-1.jpeg|link=File:StolenS4-Powder-Parts-1.jpeg|center|700px]]

[[File:StolenS4-Powder-Parts-4.jpeg|link=File:StolenS4-Powder-Parts-4.jpeg|center|700px]]

Two things I really dislike on bikes are the colors black and chrome, because of this I coated all the aluminum parts and the headlight ring an aluminum like silver, here I wanted to see how the bucket and rim would play and I think it worked out nicely.

[[File:StolenS4-Powder-Parts-2.jpeg|link=File:StolenS4-Powder-Parts-2.jpeg|center|700px]]

Finally here is Ledger smiling ear to ear checking out his bike that we are building, he is excited because it holds two people..

[[File:StolenS4-Powder-Parts-3.jpeg|link=File:StolenS4-Powder-Parts-3.jpeg|center|700px]]

==Body back from paint 02/2026==
After getting all the body work prepped, I was able to get them to Sean ad SR customs to take it away. On the color front I went a little wild and chose colors my wife would like, in fact we copied a shampoo company who's colors we liked.

I had to toss the yellow in there, I wanted a little flare on this bike on top of the loud colors, this brought the coating of the calipers and suspension link, live a little I say.

This is also the first time I have ever used the 60' Ducati livery, I don't know why this time but thought it would play well with the roundness of the Monster tank. I do love the ducati double lines of the 70s but sometimes you need to do something new..

'''First thing to know is that this bike is not going to have a black seat (brown), just have the seat here to place parts on parts!'''

[[File:StolenS4-Body-left.jpeg|link=File:StolenS4-Body-left.jpeg|center|700px]]

Lots ohh parts!
[[File:StolenS4-Body-front.jpeg|link=File:StolenS4-Body-front.jpeg|center|700px]]

As you can see, I wanted to have some fun with the front fender, hoping it plays out!
[[File:StolenS4-Body-right.jpeg|link=File:StolenS4-Body-right.jpeg|center|700px]]

Wings and things...
[[File:StolenS4-Body-tank-right.jpeg|link=File:StolenS4-Body-tank-right.jpeg|center|700px]]

The monster tail will always be one of my favorite pieces of body work every to leave Bologna. Yuck to that seat!
[[File:StolenS4-Body-tail.jpeg|link=File:StolenS4-Body-tail.jpeg|center|700px]]

Finally you can see Sean's ability to match paint to powder. Very impressive.
[[File:StolenS4-Body-front-left.jpeg|link=File:StolenS4-Body-front-left.jpeg|center|700px]]

==Wheels and tires 02/2026==

I flipped back and fourth on the wheels for this bike, mainly because I assumed I could not make the 1098 radials clear the spokes. Before trying I bought 749 wheels and assumed that was my route. For the hell of it I tried the wire wheels and the radials and as you have seen posted above, they did in fact work!

One of my other favorite things Ducati has ever done was to introduce the Sport Classic line with Aluminum rimmed spoked wheels of a normal, modern street bike tire size. 20 years ago I bought two sets of these, one went on the Monster and other to storage. The monster wheels showed signs of age and salty air on the spokes. The second were brand new but have some tarnish on the clear I hope to clean up. I decided to go with the NOS units I had and wrapped them with killer Pirelli's. Is there anything better than a SBK tire on a wire wheel set? I don't think so.

[[File:StolenS4-Body-wheels.jpeg|link=File:StolenS4-Body-wheels.jpeg|center|700px]]

==Engine Mask and paint 02/2026==

==Rolled out to see the light of day 03/2026==

With me running off for a few weeks for springbreak, I took the opertunity to get the bike rolling and activated the front braking system so that I can safely transport the bike to the Silas at Revenant Auto to fabricate the exhaust system for the bike.

It was very nice to see the bike in the daylight allbeit without all the ugly parts on it (airbox, wiring, radiator and cooling). Excuse the orange tow straps on the fork, this was just before loading to go.

==There is a story behind every bike I own 12/2024==

Warning, 17mile story ahead.

Long long ago when I was building the 888LTD for Wally, there was a need for a set of 5spoke Marchesini wheels which many know are impossible to find for the 851/888 platform. My solution at the time was to find an S4 and buy it for the wheels which we did. I found a decent bike in upstate NY and drove out and paid cash for it (well, wally paid cash for it). The bike was your base model Monster S4, all stock, red, a good bike.

After stealing the wheels I was left wondering what fun could be had with a monster when left to my own devices and I think we found the way. I sourced a set of Sport classic wire wheels and a handful of other bits and started to goto work on the bike. The first thing to do was to paint the red away which I did with BMW's laguna sec blue (the same color as my race bikes at the time), then was the wheel swap, slipper clutch, power commander, clip ons and a saw to the exhaust.

The result was awesome: A loud, fun little run around with a decent amount of power. One of the biggest challanges was getting the gold line brakes to clear the spokes on the wire wheels (remember Ducati's solution to this was to use smaller, less brakes which I was having none of). My solution was to mill down the calipers until they cleared, the risk was blowing into the backs of the calipers and making a mess of my mill (this never happened luckly!)

The bike was totally stock when purchased, here it is in the back of the truck on its way to my shop in 2007

[[File:SSPX0048.jpg|link=File:SSPX0048.jpg|center|700px]]

I quickly took the bike apart, installed clip-ons, chopped the pipes, added wire wheels and a few other things

[[File:Monster3.jpg|link=File:Monster3.jpg|center|700px]]

I then painted the bike BMW Laguna Seca Blue which was my favorite. Here was the bike in 2008 when it was in my possession still

[[File:StolenS4-FrontRight.jpg|link=File:StolenS4-FrontRight.jpg|center|700px]]

[[File:StolenS4-Front.jpg|link=File:StolenS4-Front.jpg|center|700px]]

Here you can see my mill work on the calipers to get them to clear the spokes. I know, Im nuts!

[[File:StolenS4-Caliper.jpg|link=File:StolenS4-Caliper.jpg|center|700px]]

At the time I lived with a very close friend who I trusted and who didn't have a bike. I offered the bike to him to use and was foolish enough to give him the title and let him register the bike, which he did. A time later he and I had a big falling out where I offered for him to keep the bike, only to be told "Fuck you and your bike, I don't want it". A few weeks later he moved out and the bike left with him which surprised me, after all "fuck me and my bike" right? Well, I tried for 6 or 7 years to get the bike back and was repeatedly told I could buy the bike back which I refused to do.

Time went on and the guy sold or gave the bike to a fellow, who sold or gave the bike to another fellow. Rumors of the bike being for sale floated around and I even tossed a number out there for the bike but it was far too high for what I knew the bike was worth, so I passed. My friend Rocket got a call from the guy who had the bike and was offered the thing at more than half what I was offered it (this happens to me a lot) and Rocket called me to get the bike. I was so pissed about the number that I told him to shove it (so that he would tell the guy who had it to shove it) and that was the end of it. So I thought.

==So there I was, a week before Christmas 12/2024==

The Tank is from an S4RS so it is plastic and has a modern internal, removable pickup / pump unit and the cowl is a standard monster unit which I have always had a thing for.

The plan is to have a deep blue base, with a frame matching green center section on all three items, the line on the tank will only goto the fuel fill cap. The Ducati name will come from yellow late 60s ducati stickers.

==Brake mod to clear the spokes==
The wire wheels on from the Sport Classic are very well built and therefore the spokes come off the very wide hub to get to the Rim, this made clearance a problem from the beginning. Ducati's solution was to use smaller, less good brake calipers which cleared the spokes and used an adapter. On my first go around I milled the calipers to clear the spokes which was required and which gave me proper braking at the time.

This time I was rather surprised to see that the SBK 100MM radial calipers "mostly" cleared the spokes, which the goldline calipers didn't at all. Regardless, I wanted more clearance incase a rock or a piece of a car gets in there, I don't want it to stop the from wheel.

Here you can see the caliper before being milled:

And after being milled:

These will be powder coated bright yellow which I am excited to see.

==Parts off to Powder 11/2025==
I have always loved taking this picture but I love taking the picture of the parts once they are returned far more.

We will have a a aqua frame and light bucket while having a aluminum silver swingarm, triples, clipons, rearset frames and highlight surround. We will also have yellow suspension link and calipers all around.

[[File:StolenS4-Pre-powder.jpeg|link=File:StolenS4-Pre-powder.jpeg|center|700px]]

Once again those purists out there will hate this thing but fuckem, its my bike and my wife bought it back for me and these are her favorite colors.

==Flywheel swap and a surprise 12/2025==
One of my favorite mods to these bikes is to ditch the flywheel. Lucky for me one popped up and I bought it. Pulling the stator cover off to install the flywheel, I was surprised to find and to remember the time I tossed a chain on this bike. It cracked the stator cover and luckily not the case.

[[File:Stolen4-statorcover.jpeg|link=File:Stolen4-statorcover.jpeg|center|700px]]

Here is the OE flywheel and my non-flywheel which is just big enough to hold the stator Mag and the starter bearing. While the flywheel mod makes the bike much more responsive, it can suffer around town at low revs, I don't love low revs so off it goes.

[[File:Stolen4-flywheels.jpeg|link=File:Stolen4-flywheels.jpeg|center|700px]]

Installed, you can hardly see the flywheel now.

[[File:Stolen4-flywheel-install.jpeg|link=File:Stolen4-flywheel-install.jpeg|center|700px]]

Prepping the replacement stator cover, next to original unit to the right.

==Engine Degrease 12/2025==
After years of use and storage, these motors get pretty nasty and cleaning them up is a PITA. After plugging all the holes, you drag them outside, spray them down with degrees a few times, scrape and brush, then power wash the hell out of them.

==Back From Powder 12/2025==
It is always the best time when you get your parts back from being coated. All was well but there was an issue with the lower triple so that had to stay and be re-coated, which I will grab in the new year.

When I dropped the parts off I decided to go more teal than blue on this build and I am happy that I did. I think the Teal, Dark blue and Yellow will all play nicely with one another. My wife bought me this bike (but not all the parts and the rebuild!) so I think it is only suitable that the colors been in her color wheel.

[[File:StolenS4-Powder-Parts-1.jpeg|link=File:StolenS4-Powder-Parts-1.jpeg|center|700px]]

[[File:StolenS4-Powder-Parts-4.jpeg|link=File:StolenS4-Powder-Parts-4.jpeg|center|700px]]

Two things I really dislike on bikes are the colors black and chrome, because of this I coated all the aluminum parts and the headlight ring an aluminum like silver, here I wanted to see how the bucket and rim would play and I think it worked out nicely.

[[File:StolenS4-Powder-Parts-2.jpeg|link=File:StolenS4-Powder-Parts-2.jpeg|center|700px]]

Finally here is Ledger smiling ear to ear checking out his bike that we are building, he is excited because it holds two people..

[[File:StolenS4-Powder-Parts-3.jpeg|link=File:StolenS4-Powder-Parts-3.jpeg|center|700px]]

==Body back from paint 02/2026==
After getting all the body work prepped, I was able to get them to Sean ad SR customs to take it away. On the color front I went a little wild and chose colors my wife would like, in fact we copied a shampoo company who's colors we liked.

I had to toss the yellow in there, I wanted a little flare on this bike on top of the loud colors, this brought the coating of the calipers and suspension link, live a little I say.

This is also the first time I have ever used the 60' Ducati livery, I don't know why this time but thought it would play well with the roundness of the Monster tank. I do love the ducati double lines of the 70s but sometimes you need to do something new..

'''First thing to know is that this bike is not going to have a black seat (brown), just have the seat here to place parts on parts!'''

[[File:StolenS4-Body-left.jpeg|link=File:StolenS4-Body-left.jpeg|center|700px]]

Lots ohh parts!
[[File:StolenS4-Body-front.jpeg|link=File:StolenS4-Body-front.jpeg|center|700px]]

As you can see, I wanted to have some fun with the front fender, hoping it plays out!

==Wheels and tires 02/2026==

I flipped back and fourth on the wheels for this bike, mainly because I assumed I could not make the 1098 radials clear the spokes. Before trying I bought 749 wheels and assumed that was my route. For the hell of it I tried the wire wheels and the radials and as you have seen posted above, they did in fact work!

One of my other favorite things Ducati has ever done was to introduce the Sport Classic line with Aluminum rimmed spoked wheels of a normal, modern street bike tire size. 20 years ago I bought two sets of these, one went on the Monster and other to storage. The monster wheels showed signs of age and salty air on the spokes. The second were brand new but have some tarnish on the clear I hope to clean up. I decided to go with the NOS units I had and wrapped them with killer Pirelli's. Is there anything better than a SBK tire on a wire wheel set? I don't think so.

[[File:StolenS4-Body-wheels.jpeg|link=File:StolenS4-Body-wheels.jpeg|center|700px]]

==Rolled out to see the light of day 03/2026==

With me running off for a few weeks for springbreak, I took the opertunity to get the bike rolling and activated the front braking system so that I can safely transport the bike to the Silas at Revenant Auto to fabricate the exhaust system for the bike.

It was very nice to see the bike in the daylight allbeit without all the ugly parts on it (airbox, wiring, radiator and cooling). Excuse the orange tow straps on the fork, this was just before loading to go.

==There is a story behind every bike I own 12/2025==

Warning, 17mile story ahead.

Long long ago when I was building the 888LTD for Wally, there was a need for a set of 5spoke Marchesini wheels which many know are impossible to find for the 851/888 platform. My solution at the time was to find an S4 and buy it for the wheels which we did. I found a decent bike in upstate NY and drove out and paid cash for it (well, wally paid cash for it). The bike was your base model Monster S4, all stock, red, a good bike.

After stealing the wheels I was left wondering what fun could be had with a monster when left to my own devices and I think we found the way. I sourced a set of Sport classic wire wheels and a handful of other bits and started to goto work on the bike. The first thing to do was to paint the red away which I did with BMW's laguna sec blue (the same color as my race bikes at the time), then was the wheel swap, slipper clutch, power commander, clip ons and a saw to the exhaust.

The result was awesome: A loud, fun little run around with a decent amount of power. One of the biggest challanges was getting the gold line brakes to clear the spokes on the wire wheels (remember Ducati's solution to this was to use smaller, less brakes which I was having none of). My solution was to mill down the calipers until they cleared, the risk was blowing into the backs of the calipers and making a mess of my mill (this never happened luckly!)

The bike was totally stock when purchased, here it is in the back of the truck on its way to my shop in 2007

[[File:SSPX0048.jpg|link=File:SSPX0048.jpg|center|700px]]

I quickly took the bike apart, installed clip-ons, chopped the pipes, added wire wheels and a few other things

[[File:Monster3.jpg|link=File:Monster3.jpg|center|700px]]

I then painted the bike BMW Laguna Seca Blue which was my favorite. Here was the bike in 2008 when it was in my possession still

[[File:StolenS4-Front.jpg|link=File:StolenS4-Front.jpg|center|700px]]

Here you can see my mill work on the calipers to get them to clear the spokes. I know, Im nuts!

[[File:StolenS4-Caliper.jpg|link=File:StolenS4-Caliper.jpg|center|700px]]

At the time I lived with a very close friend who I trusted and who didn't have a bike. I offered the bike to him to use and was foolish enough to give him the title and let him register the bike, which he did. A time later he and I had a big falling out where I offered for him to keep the bike, only to be told "Fuck you and your bike, I don't want it". A few weeks later he moved out and the bike left with him which surprised me, after all "fuck me and my bike" right? Well, I tried for 6 or 7 years to get the bike back and was repeatedly told I could buy the bike back which I refused to do.

Time went on and the guy sold or gave the bike to a fellow, who sold or gave the bike to another fellow. Rumors of the bike being for sale floated around and I even tossed a number out there for the bike but it was far too high for what I knew the bike was worth, so I passed. My friend Rocket got a call from the guy who had the bike and was offered the thing at more than half what I was offered it (this happens to me a lot) and Rocket called me to get the bike. I was so pissed about the number that I told him to shove it (so that he would tell the guy who had it to shove it) and that was the end of it. So I thought.

==So there I was, a week before Christmas 12/2024==

Working around the house, doing shit. Im talking to my wife and I hear this noise, a noise that is hard not to recognize, and my wife's smile which is a "I got you" smile. I start laughing and walk out to find Rocket in the driveway, sitting on the S4 in 20degree wheather freezing his ass off but cracking up! She had bought me the bike! Her words were: "Now the collection is all back together". My wife is the shit but little did she know that this move was going to cost me a ton of cash!

Here she is when it was returned to me. The Black livery is questionable, the clip-ons have been removed and a lot of other bits had been changed but overall she was still the bike I had last seen her as.

[[File:Stolen-S4-first-delivered.jpeg|link=File:Stolen-S4-first-delivered.jpeg|center|700px]]

==The buying spree begins 1/2025==

Because I know this bike so well and also know the platform in and out, before even riding this bike I did two things:
*Registered it
*Sourced most of the hard to find parts before taking it apart

The first challenge was a known one. The RI title I had last seen for this bike had a typo where an I was written as a 1 (common in RI long ago). The previous fellow decided to register it in Vermont and not deal with this. I went to the DMV, played dumb and had them check pictures of the stampings and fix the incorrect VIN.

As for sourcing parts, I went a bit haywire (shocker right). I decided go big or don't do it:
*Ohlins SBK fork with Radial bottoms (1198)
*Brembo 1198 radial calipers
*Brembo Radial master clutch and slave
*Speedymoto Monster to SBK triples
*Helibar clipons with a slight rise
*Termi spaghetti system with high mount Ti cans (Japan sourced, I have never seen these in the States, ever)
*Termi Monster 1100S cans, to be modded to fit the spaghetti systems while retaining the two up riding ability.
*Ohlins rear shock from an ST4s

The bummer about all this is the loss of the wire wheels. One of my favorite parts of this build is a monster with SC wheels but if I want radial brakes, the wheels must go, so they go because I like my brakes more than I like spoked wheels!

==Teardown and playing 10/2025==
With this bike, I didn't need to get her running, she is a runner. Right into the teardown and with it starts the mockup.

Here she is up on the lift, still basically a bike

[[File:Stolen4-teardown-1.jpeg|link=File:Stolen4-teardown-1.jpeg|center|700px]]

A little more extreme breakdown:

[[File:Stolen4-teardown-2.jpeg|link=File:Stolen4-teardown-2.jpeg|center|700px]]

This teardown will be jumping between teardown and mockup so unlike many of my other builds, this bike will look a lot more together throughout its evolution.

==Frontend build and mockup 10/2025==
For this bike I thought the 1098 / 1199 Ohlins with radials would look cool (and ride fucking awesome), the old FG43 bottoms are rad and all but really stand for the 90s and early 2000s. With the monster and all its swooping curves, the interegal radials will have a good look with the rest of the bike (I hope), additionally the final OG monster (S4RS) had radial bottoms but where a non SBK fork.

Here you can see them being serviced at Superbike services44 in New Hampshire. It always cracks me up to see the cost savings for ohlins when they only plate in gold the bits you see and not the others

[[File:Stolen4-tubes.jpeg|link=File:Stolen4-tubes.jpeg|center|700px]]

How many licks does it take to get to the center of a tootsie pop? The same can be said as to how many parts make up a front fork.

[[File:Stolen4-internals.jpeg|link=File:Stolen4-internals.jpeg|center|700px]]

When it came time to figure out the front end on this bike I was laser focused on an S4RS full front end but they were hard to find and not as good. I then remembered I had this fork in a pile but that it would require unique triples, lucky for me speedy moto dealt with this long ago and made a tripe for it. Im not a huge fan of the black anodizing but it is all I could get! Powder coating will resolve the black issue.

[[File:Stolen4-triples.jpeg|link=File:Stolen4-triples.jpeg|center|700px]]

For clipons, I went with a set of Helibars that came to me in a bulk buy. They are NOS and give me almost an inch up which should be good for 2up riding which this bike will be used for. I am also toying with wire wheels or 999 wheels, here you can see the 999 option.

[[File:Stolen4-front-test-1.jpeg|link=SFile:tolen4-front-test-1.jpeg|center|700px]]

It is always funny to see a bike with no headlight and no fairing, everything looks wrong.

Next up I have to figure out the wheel situation. Running a 999 rear in the ST / S4 swingarm is going to be challenging and at the the same time running a wire wheel in the 1098 fork has brake clearance challenges. More to come there in the coming weeks. My pref is wire but they are heavier. I don't know..

==Driveline Mockup 10/2025==
My plan was to run 749/999 wheels on this bike to allow for radial from calipers but much to my delight, the SC wire wheel spokes JUST clear the calipers, I will be milling them a tad just to allow for some more room.

Sticking with the wire wheels on this build makes me very happy, for some reason I have always loved the look of the SC aluminum hub / rim wheels along with road tires (which are not what are on these wheels right now). I have another set of wheels that are un-used that will be getting a set of road tires mounted in the coming weeks.

Monsters look funny without the big ass rearsets installed as you can see. I was thinking about doing away with them for the aesthetic but I want this bike to be good for two up riding so they will be sticking around.

[[File:Stolen4-driveline-mock-1.jpeg|link=File:Stolen4-driveline-mock-1.jpeg|center|700px]]

The ST4S rear shock mounted well and the rez plumbing clears the frame the way I had hoped. Here you see the rebound adjuster
[[File:Stolen4-driveline-mock-2.jpeg|link=File:Stolen4-driveline-mock-2.jpeg|center|700px]]

On the other side you see the compression adjust / rez with the line fitting well in the frame.
[[File:Stolen4-driveline-mock-3.jpeg|link=File:Stolen4-driveline-mock-3.jpeg|center|700px]]

Im testing the OG cast iron floating rotors on one side to see how the clearance is, which is perfect. For some reason I love these Tron looking rotors and am happy to have a bike I can run them on (6 bolt with the correct offset), all my other bikes are so modified I had to go other directions.
[[File:Stolen4-driveline-mock-4.jpeg|link=File:Stolen4-driveline-mock-4.jpeg|center|700px]]
==Body work planning 11/2025==
Talking about bodywork on a monster is the wrong way to put it but I had to come up with something. Those that know the monster know it's entire market is based on the lack of bodywork but here we will talk about the three major parts:
Tank: Monster S4RS
Front fender: Monster 1100S
Seat cowl: Monster S2R

To start I always like to switch it up with the front fenders on these builds so after poking around, I settled on a very modern looking 1100S monster fender, My fingers are crossed here. The Tank is from an S4RS so it is plastic and has a modern internal, removable pickup / pump unit and the cowl is a standard monster unit which I have always had a thing for.

I flipped back and fourth on the wheels for this bike, mainly because I assumed I could not make the 1098 radials clear the spokes. Before trying I bought 749 wheels and assumed that was my route. For the hell of it I tried the wire wheels and the radials and as you have seen posted above, they did in fact work!

One of my other favorite things Ducati has ever done was to introduce the Sport Classic line with Aluminum rimmed spoked wheels of a normal, modern street bike tire size. 20 years ago I bought two sets of these, one went on the Monster and other to storage. The monster wheels showed signs of age and salty air on the spokes. The second were brand new but have some tarnish on the clear I hope to clean up. I decided to go with the NOS units I had and wrapped them with killer Pirelli's. Is there anything better than a SBK tire on a wire wheel set? I don't think so.

==Rolled out to see the light of day 03/2026==

With me running off for a few weeks for springbreak, I took the opertunity to get the bike rolling and activated the front braking system so that I can safely transport the bike to the Silas at Revenant Auto to fabricate the exhaust system for the bike.

It was very nice to see the bike in the daylight allbeit without all the ugly parts on it (airbox, wiring, radiator and cooling). Excuse the orange tow straps on the fork, this was just before loading to go.
