Key specifications
Overview
Introducing the 2007 Buell Firebolt XB12R, a striking embodiment of American motorcycle engineering that carved out a niche in the naked bike category. Designed with precision and performance in mind, the Firebolt XB12R appeals to riders who crave agility, power, and a visceral riding experience. Standing out with its distinctive styling and innovative design features, this motorcycle is not just a mode of transport; it’s a statement. The Firebolt is engineered for those who appreciate the fusion of raw power and sleek aesthetics, making it a memorable ride for both city commutes and weekend escapades. At the heart of the Firebolt XB12R lies a formidable 1202.88 cc V2 engine that delivers an exhilarating 103 horsepower at 6800 RPM and a robust torque of 113.90 Nm at 6000 RPM. This powerful powertrain ensures that riders feel the immediate response and acceleration, ideal for weaving through traffic or tearing up winding roads. The engine's design features a compression ratio of 10.0:1 and a sophisticated DDFI II fuel injection system, which collectively enhance its efficiency and throttle response. Coupled with a 5-speed gearbox and a belt final drive, the Firebolt provides smooth and precise shifting, allowing riders to harness its power with absolute confidence. The Firebolt's impressive performance is complemented by its advanced chassis and suspension technology. The aluminum frame, featuring the Uniplanar™ powertrain vibration isolation system, ensures a lightweight structure while minimizing vibrations for a more comfortable ride. The front suspension boasts 43 mm Showa inverted forks, fully adjustable for compression damping, rebound damping, and spring preload, while the rear is equipped with a Showa coil-over monoshock with similar adjustability. This careful engineering translates into a nimble handling experience, with a rake of 21.0° and a trail of 84 mm, providing stability in corners and responsiveness during quick maneuvers. Additionally, the Firebolt’s stylish Midnight Black finish contrasted with Translucent Red wheels amplifies its sporty look, making it as visually appealing as it is thrilling to ride. **
