Since Ducati has hit the racing scene it has remained top of the line. The 2012 Streetfighter is just that. A speedy 849 cc, four-stroke, dual overhead camshaft (DOHC), longitudinal twin-cylinder engine makes this motorcycle tear through the streets. It has been newly designed to reduce the engine overlap from 37 degrees to 11 degrees. This innovation This invention increases power, reduces the consumption of gas, and decreases emission output. The improvements made allow it to achieve full torque of 69 pounds per feet (lb-ft) of torque while maintaining a low 9500 revolutions per minute. This allows for higher and more consistent power. It is fuel injected with elliptical throttle bodies and is liquid cooled. The camshaft case cover and clutch cover have been made with magnesium alloy to reduce the weight to increase performance. The crankcase has been revamped and made by die cast under vacuum. It has decreased the weight and made it stronger by increasing the wall thickness. This manual, six-speed clutch has also been redesigned to decrease the weight. The use of a wet-clutch has made shifting smoother and decreased the weight by 2.2 pounds. The new camshafts have been improved also. They are 1.5 mm larger and have 4 degrees longer duration that has gone to make this ride even faster and smoother. With all of this power it needs even better stopping power. Dual hydraulic disc brakes with four 35 mm pistons provide braking power in the front and the rear brakes consist of a single hydraulic disc brake with two pistons.
