Engine
Powering this streetfighter is a Thunderstorm® 1203 cc, 45-degree V-Twin. A stump-pulling, gut-wrenching, air-cooled torque machine.
For 2008, Buell advances the performance of its air/oil/fan-cooled Thunderstorm® V-Twin engine series with a larger crank pin, an improved oiling system, and a new electronic timing system and ECM that controls an all new DDFI 3 fuel injection system. Combined, these changes improve drivability and performance, and reduce service maintenance costs. Also new for 2008, the Thunderstorm® 1203 redline is increased to 7100 rpm from 6800 rpm, giving this engine an even broader powerband, and riders the ability to accelerate longer and downshift at a higher rpm.
