At the heart of the 2005 Buell Firebolt XB9R sport motorcycle, Buell utilizes a 984 cc (60 cu in) oil & air-cooled v2, four-stroke layout. In factory specification, peak output is rated at 92 HP (67.2 kW) at 7,500 rpm while maximum torque reaches 94.9 Nm (70 lb-ft) at 5,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and shaft drive (cardan) final drive. With a specific output of 93.5 HP per liter and a 2,000 rpm working window between peak torque (5,500 rpm) and peak power (7,500 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the Firebolt XB9R measures 174.6 kg (385 lbs) dry, translating to a power-to-weight ratio of 0.53 HP/kg (1.9 kg per horsepower). 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-liter (3.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
