The 1125RR is designed to give privateer racers a turn-key machine to compete in the American Superbike class in AMA Pro Racing,” said Buell, the Chairman and Chief Technical Officer of Buell Motorcycle Company. “We want to build on our program that has proven so successful for privateers in the Daytona SportBike class.The Buell 1125RR uses some race components already used on 1125R that has taken victories in the Daytona SportBike class, such as a billet axle-adjustment system for the aluminum swingarm that incorporates chain drive for simpler gearing changes. In the axle’s center position, the double-R has a 55.5-inch wheelbase, up nearly an inch from the streetbike’s 54.6 inches. The chassis itself is unchanged from the standard 1125R’s twin-beam aluminum frame that doubles as the bike’s fuel tank.
