The Buell 1125R, a sport bike made by Buell Motorcycle Company, debuted in July 2007 for the 2008 model year. Production ceased in October 2009, but founder Erik Buell launched Erik Buell Racing in November 2009, initially focusing on race-only versions of the 1125R. Powered by a 1,125 cc (68.7 cu in) Helicon V-twin engine from BRP-Powertrain (Rotax) of Austria, the liquid-cooled engine boasts 146 hp (109 kW) and a 10,500 rpm limit. The bike's design features include a patented frame that holds the fuel, a unique single, eight-piston front brake called ZTL2, and an exhaust under the engine for increased volume. The 1125R emphasizes mass centralization, using a drive belt instead of a chain for its transmission.
