At the heart of the 2010 Buell XB12R Firebolt naked motorcycle, Buell relies on a 1202.9 cc (73.4 cu in) oil & air-cooled v2, four-stroke powerplant. In factory specification, peak output is rated at 103 HP (75.2 kW) at 6,800 rpm while maximum torque reaches 114 Nm (84.1 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and belt final drive. With a specific output of 85.6 HP per liter and a 300 rpm working window between peak torque (6,500 rpm) and peak power (6,800 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
Rider ergonomics and chassis geometry center around a 775 mm (30.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,321 mm (52 in) wheelbase engineered for quick, flickable steering geometry. The 14.45-liter (3.8 US gal) fuel tank paired with a rated consumption of 4.9 L/100 km provides an estimated theoretical range of roughly 295 km (183 miles) between fill-ups.
