The single, eight-piston front brake, called ZTL2, has a inverted rotor that is directly attached to the front wheel rim. This enabled Buell to design a front end that was lighter and more responsive than traditional designs. The bike also uses an exhaust under the engine for greater volume. The frame, front end and exhaust all contribute to Buell's main design aim of mass centralization. Instead of a drive chain the 1125R uses a drive belt, which does not require lubrication or adjustment.
