At the heart of the 2008 Buell Lightning XB12Scg naked motorcycle, Buell pairs a 1202.9 cc (73.4 cu in) oil & air-cooled v2, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 103 HP (75.2 kW) at 6,800 rpm while maximum torque reaches 113.9 Nm (84 lb-ft) at 6,000 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 800 rpm working window between peak torque (6,000 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.
On the scales, the Lightning XB12Scg measures 179.2 kg (395 lbs) dry, translating to a power-to-weight ratio of 0.57 HP/kg (1.74 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,316 mm (51.8 in) wheelbase engineered for quick, flickable steering geometry. The 14.45-liter (3.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
