Positioned in Buell's sport motorcycle lineup, the 2006 Buell Firebolt XB9R relies on a 984 cc (60 cu in) oil & air-cooled v2, four-stroke powerplant. In factory specification, peak output is rated at 92 HP (67.1 kW) at 7,500 rpm while maximum torque reaches 94.9 Nm (70 lb-ft) at 5,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and belt final drive. With a specific output of 93.5 HP per liter and a 2,500 rpm working window between peak torque (5,000 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 175 kg (386 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 1,318 mm (51.9 in) wheelbase engineered for quick, flickable steering geometry. The 14.5-liter (3.8 US gal) fuel tank paired with a rated consumption of 4.1 L/100 km provides an estimated theoretical range of roughly 354 km (220 miles) between fill-ups.
