A premium performance motorcycle, the Firebolt XB12R is powered by a 1203 cc Buell Thunderstorm V-Twin engine that revs to 6800 rpm while pounding out 103 peak horsepower and 84 ft. lbs. of torque, delivered in a powerband so broad that serious thrust is always on tap. The Buell InterActive Exhaust system utilizes a valve in the dual-chamber muffler that is controlled by the ECM and adjusts exhaust flow according to riding conditions to smooth torque delivery and optimize engine power. The XB12R has a Graphite Gray frame, and is available in Midnight Black with Cherry Bomb Translucent red wheels and a Cherry Bomb Translucent red windscreen, or in Sunfire Yellow with Designer Black wheels and a Kick Ash Translucent windscreen.
