The Buell 1125R – a motorcycle that shatters conventions and redefines the superbike category. Powered by the potent 1125cc liquid-cooled V-Twin Helicon engine, this beast generates an astonishing 146 crank hp and 82 ft-lbs of peak torque.
With its foundation rooted in the Buell Trilogy of Technology, the 1125R delivers optimum performance while staying true to Buell’s original sense of sportbike style and design. For 2009/10, targeted fuel injectors, relocated O2 sensors, and updated engine spark and fuel maps join the fray, offering improved drivability, crisper throttle response, and enhanced fuel economy.
The 1125R is a masterclass in engineering, with fully adjustable Showa forks up front, an eight-piston caliper on the Buell ZTL2 front brake, and a smooth-shifting six-speed transmission paired with a HVA slipper-action clutch. Quiet Zone aerodynamics optimize airflow around the rider, while the fairing shape was honed using Computational Fluid Dynamics (CFD) analysis.
In short, the Buell 1125R is an uncompromising package that combines thrilling performance, advanced technology, and style in equal measure – a must-ride experience for any serious motorcyclist.
