The XB12R is the big-engine version of Buell's fully faired sportbike, using the 1203 cc air-cooled Thunderstorm twin in the aluminium frame that stores fuel. For 2007 it carries on with the Interactive exhaust valve, ZTL front brake and belt drive, with strong midrange torque and short-wheelbase handling.
