Built around Buell's enduro - offroad motorcycle platform, the 2006 Buell Ulysses XB12X 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 Ulysses XB12X measures 192.8 kg (425 lbs) dry, translating to a power-to-weight ratio of 0.53 HP/kg (1.87 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,374 mm (54.1 in) wheelbase engineered for quick, flickable steering geometry. The 16.65-liter (4.4 US gal) fuel tank paired with a rated consumption of 4.05 L/100 km provides an estimated theoretical range of roughly 411 km (255 miles) between fill-ups.
