CAST-IRON 70cc  CYLINDER KIT M317083

 

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

The cast-iron cylinder kits produced by Malossi s.p.A. are designed and manufactured with the specific abjective 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 fuid mechanics of the cylinder kit with fanatical precision (see the tranfer pipes, exhaust and combustion chamber), thereby obtaining a high level of turbolence in the combustion chamber. The latter has permitted a substantial reduction in specific consumption and a drastic reduction in the exhaust emission of pollutants.
