Vehicle Information
Buell 1125R Motorcycle - Street (2008-2010)
The Buell 1125R, produced from 2008 to 2010, is a high-performance sport motorcycle known for its distinctive design and powerful engine. It was powered by an 1125 cc Helicon liquid-cooled, 72-degree V-twin engine, delivering approximately 146 to 148 horsepower and 111 Nm of torque. Throughout its production, the 1125R was offered as a single model, without distinct trim levels. While the core engine remained consistent across these years, significant updates were introduced, particularly for the 2009 and 2010 models. For 2009 and 2010, enhancements included targeted fuel injectors, relocated O2 sensors, and updated engine maps to improve drivability, throttle response, heat management, and fuel economy. A new gear position readout was added to the instrument panel, and a high-output alternator was introduced. Chassis improvements included slider bobbins on the swingarm. Further refinements for 2010 involved new front brake master cylinder components, LED taillights and rear turn signals, updated oxygen sensors, and new graphics.
