The Ducati Streetfighter is intended to set the benchmark for a new generation. The engine is a specifically tuned version of the 1098, delivering a claimed 155 horsepower and 85 foot-pounds of torque at, oddly enough, the same 9500 rpm. Claimed dry weight is 374 pounds for the standard model.
The chassis uses the same 34mm-gauge steel-tube frame of the 1098, but the rest is new. Marking a meaningful evolution in Ducati's chassis philosophy, wheelbase was stretched more than 1.5 inches to span 58 inches. The extra length came mostly from the longer single-sided swingarm, while the rest was derived from steering angle, kicked out to 25.7 degrees from the 24.5 degrees of the 1098, to produce a 4.5-inch trail.
The 1198 is also new for 2009. The 1098 replacement shares its 106mm bore and 67.9mm stroke with the 1098R, now known as the 1098R Troy Bayliss Edition (limited to 500 examples worldwide). The 1198 sports 43.5mm intake and 35.3mm exhaust valves, throttle bodies that retain the previous model's elliptical configuration, now enlarged to a corresponding 63.9mm circular diameter, and a 12.7:1 compression ratio.
