A premium sportfighter motorcycle,

geometry for nimble, intuitive handling. The 1203cc Buell Thunderstorm V-Twin
engine makes 103 peak horsepower at 6800 rpm, and 84 ft. lbs. of peak torque at

controlled by the ECM and adjusts exhaust flow according to riding conditions to
smooth torque delivery and optimize engine power. The Firebolt features clip-on
handlebars for optimal control, an aerodynamic quarter-fairing with dual
projector-beam headlamps, and a sleek, covered passenger pillion. The suggested
