First unveiled at the 1992 Cologne Motorcycle Show, the Ducati M900 Monster was the “original naked bike”. The wildly successful parts-bin special was penned by Miguel Galluzzi and quickly became one of the Bologna firm’s best-selling models, accounting for more than half of all of Ducati’s sales within a decade of its release.
As Ducati’s superbikes evolved, so too did the Monster lineup. But by the middle-aughts, the Italian marque was facing increasingly fierce competition from fellow European manufacturers like Triumph and KTM. So in 2006, Ducati shoehorned the powertrain from its 998 superbike into the Monster. Two years later, Ducati one-upped itself, this time delivering what was essentially a naked version of its World Superbike Championship-winning 999 model. Dubbed the S4RS, the naked was powered by Ducati’s Testastretta 999 engine. The water-cooled narrow-head motor featured Marelli FI with competition-derived 12-hole injectors and an auxiliary oil cooler. The race-bred L-Twin redlined at 10,500 rpm, putting down 130 hp at 9,500rpm and 77 ft-lbs of torque at 7,500rpm. Despite being housed in Ducati’s trademark tubular trellis frame, the company’s designers did a stellar job of hiding the model’s slew of wiring and sensors so they could highlight the crown jewel of the bike: the engine.
The 390lb (177kg) S4R S also boasted an array of competition-grade componentry, much of it borrowed from the R-spec 999. 43mm inverted Öhlins forks with low-friction titanium nitride coating, Öhlins monoshock, aluminum single-sided swing-arm, four-pot Brembo P34 brakes with dual 320mm discs, and ten-arm alloy Marchesini rims were all standard fare on the hopped-up naked.
In 2008 Ducati released the “ultimate expression of the Monster” via a limited run of only 400 Tricolore edition S4RS’s — 250 of which were sent to the US. Adorned in the classic Italian flag livery, the S4RS Tricolore also featured a carbon fiber front fender, radiator cover, side-covers, cam belt covers, and heat guard and silencer cover for the model’s stacked dual aluminum exhaust. Each of the 400 units also came with an individualized number plate.
This example is VIN: ZDM1RB5T18B112769. The seller acquired it less than a year ago from a private party in New Mexico.
During his ownership, the seller has covered less than 250 miles. The odometer shows 2,710 miles.
It is production number 150 out of 400.
“I have the privilege to own two numbered special edition Ducati Monsters and I’ve made the tough decision to part ways with this one. I have dreamed of experiencing the formidable 2008 Monster S4RS Tricolore for nearly 2 decades so I’m beyond appreciative to have fulfilled that dream. On to the next dream bike.” The seller also recently sold a Ducati 998S Final Edition here on Iconic Motorbike Auctions.

Cosmetic Blemishes: please see the album in the “Photos” tab for all known cosmetic blemishes. Here is a selection:
“It’s a practically flawless motorcycle. If there was a part that was aged, I swapped with OEM Ducati parts. For example, the clear windshield was weathered, aged, had fine scratches, so I ordered an OEM windshield from Ducati. The clutch and brake reservoirs were yellowed so I ordered 2 new ones from Ducati. I made this bike perfect intentionally. If anything, and to be supremely picky, when you look very closely at a certain angle you can see slight swirling where your jacket touches the tank.”
Currently located in Winchester, California, this Ducati is offered on a clean California title with registration current through July 2027.
