At the heart of the 2010 Buell 1125R sport motorcycle, Buell pairs a 1125.9 cc (68.7 cu in) liquid-cooled v2, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 146 HP (106.6 kW) at 9,800 rpm while maximum torque reaches 111.2 Nm (82 lb-ft) at 8,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and belt final drive. With a specific output of 129.7 HP per liter and a 1,800 rpm working window between peak torque (8,000 rpm) and peak power (9,800 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
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 1,387 mm (54.6 in) wheelbase engineered for quick, flickable steering geometry. The 20-liter (5.3 US gal) fuel tank supports practical everyday commuting and weekend road stints.
