“The Buell 1125RR is designed to give privateer racers a turn-key machine to compete in the American Superbike class in AMA Pro Racing. We want to build on our program that has proven so successful for privateers in the Daytona SportBike class,” said Erik Buell, Chairman and Chief Technical Officer, Buell Motorcycle Company. This racing bike features a modified Helicon 1125cc (103mm bore x 67.5mm stroke) liquid-cooled 72-degree V-Twin engine. Power increases come from components including a larger airbox and intake manifold, revised valves and camshafts, a higher compression ratio, titanium exhaust system and other weight-reduced components.
The 1125RR chassis is the standard 1125R design with fuel-in-the-frame, plus a billet axle adjustment system and chain-drive to allow gearing changes. Suspension travel is managed by fully adjustable units, with a Showa 43mm front fork and a remote-reservoir rear shock. A ZTL2 (Zero Torsional Load) eight-piston front caliper is mated with a modified front rotor. Buell Motorcycles.
