Most parents recite this and Italian folks are no different, so it’s no surprise that the heart of the Streetfighter is Ducati’s tried-and-true liquid-cooled 1099cc L-Twin engine as used in the 2008 Ducati 1098 Superbike. The Streetfighter, however, benefits from a new vacuum die-cast manufacturing process (first introduced on the 2008 Ducati 848) allowing for a lighter crankcase without compromising its strength.
The cylinders use the same 104 x 64.7mm bore/stroke dimensions as the 1098. The cylinder head is also the same, making use of four 42mm intake valves and an equal number of 34mm exhaust valves controlled via Ducati’s unique Desmodromic valve actuation system.
Fueling the engine is a pair of Marelli fuel injectors that pump fuel into elongated oval-shaped throttle bodies. The injectors receive fresh air via a modified air tract that is required due to the Streetfighter’s unique front facia design. The results is a claimed five horsepower decrease in power output.
