70cc Malossi cast-iron cylinder kits: the best balance between component performanceand life of the component. This kit will fit  and other scooters with a 50cc 2T Piaggio engines.

The cast-iron cylinder kits produced by Malossi s.p.A. 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 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.

Technical features:

- Material: wearproof, laminate special cast iron
- Recalculated heat exchange surfaces
- NC machine-tool machining
- Transfer and exhaust disigned for maximum efficiency
- Lightened and reinforced, special aluminium alloy pistons with a high silicon content
- Optimized compression ratio
- Very high turbulence combustion chamber

 

DONT FORGET TO ADD ABOUT A oz OF OIL TO THE FUEL TANK WHEN FILLING. YOU STILL HAVR YOUR 50cc OIL PUMP AND NOW YOU HAVE A 70cc.
