This slightly used Streetfighter S comes with nice extras including a Tail Tidy, Solo Tail section, Comfort Seat, Rizoma reservoirs, Rizoma gas cap, Bar End mirrors, Frame Sliders, Axle sliders, added windscreen and radiator guards. The Streetfighter V4 S is the premium naked sports machine from Ducati. The Streetfighter V4 S features exotic styling, a powerful engine, and distinctive Italian design language. The SF V4 S uses Ducati’s 1,103cc Desmosedici Stradale V4 engine that produces 208 horsepower and 90.4 lb-ft of peak torque, with all of the top tier riding aids and electronics that Ducati has to offer. These include traction control, riding modes, cornering ABS, and much, much more. The features that separate the Streetfighter V4 S from the standard V4 are numerous. The most obvious and noticeable include the upgraded suspension. The V4 S is fitted with fully-adjustable Öhlins suspension at the front and rear. Other notable upgrades include the addition of Marchesini forged rims and the addition of lighter weight components that enable the Streetfighter V4 S to weigh 5 lbs less than the standard version.
