2010 Erik Buell Racing 1125RR ASB Technical Analysis & Specification Breakdown

Engineered by Erik Buell Racing for the sport motorcycle segment, the 2010 Erik Buell Racing 1125RR ASB pairs a 1126 cc (68.7 cu in) v2, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 170 HP (124.1 kW) at 11,500 rpm while maximum torque reaches 116.6 Nm (86 lb-ft) at 10,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 151 HP per liter and a 1,500 rpm working window between peak torque (10,000 rpm) and peak power (11,500 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.

On the scales, the 1125RR ASB measures 166.9 kg (368 lbs) dry, translating to a power-to-weight ratio of 1.02 HP/kg (0.98 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,400 mm (55.1 in) wheelbase engineered for quick, flickable steering geometry. The 17.41-liter (4.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
