Malossi Sport 50cc cylinder kit for Piaggio/ Gilera/ Vespa 50cc air-cooled 2-stroke engines.

Malossi cast-iron cylinder kits: the best balance between component performance and life of the component.

The cast-iron cylinder kits produced by Malossi are designed and manufactured with the specific objective of obtaining high combustion efficiency, long life, and a reliability that suits the Malossi name. Owing to the experience gained in the preparation of cylinder kits for race, Malossi engineers have developed the thermodynamics of cast-iron cylinder kits to the fullest and designed the inner fluid mechanics of the cylinder kit with fanatical precision (see the transfer pipes, exhaust and combustion chamber), thereby obtaining a high level of turbulence in the combustion chamber. The latter has permitted a substantial reduction in specific consumption and a drastic reduction in the exhaust emission of pollutants.
