Malossi MHR 70ccm is one of the most powerful cylinder kits for air-cooled engines. The cylinder kit is made of aluminium, has an internal bore of 47.6mm and is very durable with a strong nikasil lining. It has high flush channels and due to the two-part exhaust port, it is a cylinder kit that works best at high revs. In order to achieve sufficient internal cooling, Malossi recommends that as min. 19mm carburettor is used.
Purely in terms of performance, we recommend that the cylinder kit be used in combination with a 21-28mm carburettor, a high-revving exhaust and a racing clutch. A spark plug with a short thread must be used for this cylinder. The cylinder kit is delivered complete incl. gaskets, piston ring etc.
Note: The cylinder cannot be fitted to models from 2003->, unless the restriction in the engine block is removed. If the cylinder is fitted, it is no longer possible to use the original or other Euro2 exhausts. Both parts apply to models from 2003->. This does NOT apply to PGO engines.
