Venandi 85cc cylinder head for the conversion of Simson KR51/1 or SR4- Star to a M500 engine.
With this special design, it is possible to exchange engines of the older generation (M53-M54) for the newer series (M531-M742). Without changes to the frame, the engine can be mounted to the cylinder head like before.
