Buell 1125R, 2009

Buell 1125R 2009

The superbike category of Buell 1125R is powered by the 1125 cc liquid-cooled 72-degree V-Twin Helicon engine generating 146 crank hp and 82 ft. lbs. of peak torque. With a foundation built on the core Buell Trilogy of Technology creating optimum performance, the 1125R remains true to Buell’s original sense of sportbike style and design.
The new gear position readout is added to the digital display on the instrument panel as a scroll-to feature. A high-output alternator has increased capacity for accessory use. Slider bobbins have been added to the swingarm for protection and easy use of a rear stand.
The front wheel rides on fully adjustable Showa 47 mm upside-down forks, while the Buell ZTL2 front brake has an eight-piston caliper. A smooth-shifting six-speed transmission works with a HVA (Hydraulic Vacuum Assist) slipper-action clutch that uses engine vacuum for easy clutch-lever action and reduced engine braking during downshifts.
The Quiet Zone aerodynamics optimize air flow around the rider for enhanced race performance and rider comfort. The fairing shape was developed using Computational Fluid Dynamics (CFD) analysis, and features six-bulb headlamps, while LED turn signals are integrated into the mirror housings.
