2008 Ducati Monster S4RS R Side FrontThe water-cooled Monster S4RS was a great engine in search of a bike. It was spawned from the original Monster that was itself the proverbial Franken-bike: frame from an 888, suspension and wheels from the 900SS-CR, and a dash that looks like someone ripped the idiot light cluster straight out of a Fiat. They’ve got very poor steering lock, thanks to that superbike frame, they’re terrible for highway riding, and only seem to fit you if you’re  5’8″… But they were an affordable, almost practical way into Ducati ownership, and were originally powered by the classic air-cooled L-twin engine that had all the performance most riders would ever need.

Eventually, they gave the fans what they’d been clamoring for by sticking the water-cooled four-valve engine into the bike to keep it competitive compared to more modern alternatives from Triumph and KTM.

Obviously, a water-cooled engine needs a radiator, and then the RS version added a very trick, but still sort of tacked-on-looking oil cooler below the not-so-trick-looking radiator. And all those extra bits and associated plumbing looked like the afterthoughts they were, cluttering up what was originally a pretty clean design.

And then there’s the handling. While other bikes got the sport naked package right, the Monster RS didn’t quite live up to the hype, in spite of top-flight Öhlins front and rear and superbike brakes. Basically, the 130hp 998cc Testastretta engine overwhelmed the chassis, making riding the bike less of a dance and more a back-alley street fight. And I mean, what’s really the point of a 150mph naked bike? Aside from bragging rights?

From the original eBay listing: 2008 Ducati Monster S4RS for Sale

This is a 2008 Ducati, S4R Tricolore Testastretta.  This is a very rare bike, and to my knowledge is the only model in Utah or surrounding states. There were only 400 of these motorcycles produced in 2008.  This bike is number 52, as verified by the tag over the alternator cover.

This is a 999S, fully liquid cooled engine, Brembo brakes.  Mileage is a little over 18K.  Tires have approximately 85 miles on them.  They are Pirelli Diablo Rosso II’s.  Pipe for Termignoni black carbon fiber pipes.  Chain is new and tight zero rust.  

This bike has never seen rain.  Stored inside and covered during winter months.  No damage, never been in an accident, layed down or tipped over.  All scheduled maintenance performed on or before schedule date by authorized Ducati mechanic.  

Includes bike storage stand


The parts that went into the S4 didn’t quite gel into a complete motorcycle and, unless posing and wheelies are your game, the water-cooled Monsters might prove a bit of a disappointment. Fine, if that’s what you’re into, since the S4RS is very good at both activities. But there are better choices out there if you want a fast, naked twin.

That being said, the Tricolore S4RS is really the best-looking of the water-cooled Monsters, and this one looks like it’s in extremely nice condition. It comes with a pair of shotgun Termignoni pipes already on the bike which, to my ear, sound much better than the Arrows often fitted. It otherwise appears to be completely stock, and that factory rear fender has my right hand itching to grab a hacksaw… The miles aren’t the lowest, but Ducati engines can last a long time when well-maintained.

Unfortunately, there’s been zero interest in the bike so far, with just about a day left on the auction and no takers yet at a $7,850.00 starting bid. I think these will one day have some real value but right now, prices of the early Monsters have bottomed out, possibly dragging these down with them.

  • Funny how this Article reads as if the writer owned one. Yet I have the feeling her/himself has never even seen one in person. True it is not a super bike, it’s more of a hot rod. Very impractical, way to big of engine for you to ever use it all on the streets and yet you want to drive it all day long. You don’t mind that rough ride or that amazing sound. Oh wait i just described the s4rs. I have been on a few nice bikes in my day and i must say this was one of my favorites. It railed canyons way faster then anyone should go. Sounded amazing, like a race bike. Finish was top shelf. Sure your wrist/back might of hurt after a few hours on the thing ( as any good bike should). If you want to RIP on monsters try going for the ones that have less 🏇power then my dirt bike. Those are the joke…

    • I’ve seen the S4RS in person many times, and I’ve ridden quite a few Monsters over the years. From all three generations, in fact, and I happen to like them all. But I still think the water-cooled Monsters look cluttered, and I’ve read a number of reviews from expert riders criticizing the handling. They’re quick, for sure, and probably great for attacking back roads at 7/10th’s. But considering what they cost new, the overall package didn’t quite work as well as, say, a KTM SuperDuke. Here, I’ll quote the UK’s Fast Bikes Magazine: “On paper, it all looked good. But said paper didn’t pick up on an odd riding position, wild power delivery, and hectic antics.”

  • lets not be so quick to praise ktm, the company that buys into the nanny state BS that literbikes are “too fast” doesnt deserve it

  • “But to me, that’s when the bike really jumped the shark.” -Well said Tad.

  • In my opinion, probably the nicest Monster ever made.

    Second place goes to the 2006 S4R in Blue w/ White stripes.


    • Always appreciate the $.02 guys! And there’s obviously nothing wrong with loving a [debatably] flawed bike: I’d say flawed bikes are even easier to love than technically perfect machines. They’re certainly more fun to write about!

  • I’ve owned my 07′ S4rs since new and can honestly say it’s one of the best bikes I’ve ridden. Commuting, back roads, and the occasional track day…it handles it like a champ. Is it the most comfortable bike? No, but that is missing the point. Great suspension that can be set to meet anyones’ needs and arguably the greatest brakes ever fitted to a streetbike make for a bike that is very easy to ride quickly. Obviously I’m biased, I own the thing. It’s the fifth Ducati I’ve had over the years and it still puts a big grin on my face every time I take it out. Just my 2 cents

  • Scariest Monster ever! Cool, even for a diesel. I would thrash the hair off it…

  • DON’T BUY IT!!!!!!!
