"In order to achieve the higher engine speeds necessary for use in racing, however, the cylinder head has been redesigned. A modified valve operating system activates the enlarged intake and outlet valves. Other changes include the altered inlet and outlet channels ducts, new forged pistons and adapted connecting rods. A new titanium exhaust system helps provide an optimum torque curve. As usual, the engine management system is taken care of by the BMW Motorrad BMS-K, though here it has a revised characteristic map for racing purposes.
As a result of these modifications, engine output has been increased to well over 130 bhp. The engine speed limit is around 9500 rpm."
