SOHC single-cylinder engine • 70° cylinder angle • sportily compact engine design with a revolutionary layout • reduced to a minimum • everything that is superfluous has been omitted • top performance • high reliability • the crankshaft is positioned near the overall centre of gravity • for optimum handling • starts only with an electric starter. Oil circuit with pressure pump • reliably supplies lubricating oil to all the essential components, such as the crankshaft, piston and valve-train • a suction pump carries excess oil out of the cylinder head and back to the transmission • a single oil filter • easy maintenance. The single overhead cam in the cylinder head activates the titanium intake valves via lightweight rocker arms • minimal oscillating masses • larger valve cross-sections and a shallow valve angle for increased performance • the magnesium cylinder head cover is attached at an angle for simple servicing • the camshaft simultaneously serves as a centrifuge for the engine ventilation.
