Complete factory service and repair manual for the 2007 Buell Firebolt XB12R sport motorcycle covering engine, chassis, electrical systems, and all maintenance procedures.
2007 Buell Firebolt XB12R Service Repair Manual
VEHICLE/EQUIPMENT INTRODUCTION
The 2007 Buell Firebolt XB12R represents Erik Buell s vision of an American sportbike that defied convention. Built around a revolutionary design philosophy, the Firebolt utilized the Harley Davidson 1203cc Revolution V-twin engine mounted low and forward in an aluminum spar frame to centralize mass and achieve handling characteristics that rivaled Japanese supersport machines.
The XB12R platform featured a perimeter spar frame constructed from aircraft grade 6061-T6 aluminum with the engine serving as a stressed member. This architecture delivered exceptional torsional rigidity while keeping the chassis remarkably light at barely one-third of the total bike weight. The Firebolt was the sport-oriented variant in the XB lineup, featuring aggressive forward-leaning ergonomics, clip-on handlebars, and rear-set footpegs for track-inspired riding posture.
The 1203cc air/oil/fan-cooled 45-degree V-twin produced approximately 92 horsepower and 85 lb-ft of torque through a tuned Evolution-derived architecture. Twin spark plug heads with 54mm bore and 63mm stroke delivered strong midrange punch characteristic of V-twin engines. The Firebolt XB12R distinguished itself from the standard XB12S Streetfighter with its fully faired bodywork and racier ergonomics.
