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 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.

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

  • Q. What premix ratio shall i use for this kit?
  • A.

    Use 40:1 of good quality fully synthetic oil if you are going to premix. You don't need to premis though, you can use the standard autolube without changing it so long as you use good quality fully synthetic oil.

  • Q. Does the kit come with the piston rings
  • A.

    yes, it is a complete kit

  • Q. What spark plug is used for this cylinder kit?
  • A.

    use NGK BR9ES

  • Q. Does this cylinder kit need to be fitted with a performance crank?
  • A.

    The Malossi sports iron kits create their power at fairly low revs and are normally fine on a standard crank. It depends a little on what condition your standard crankshaft is in though, if it is high mileage or you are taking the engine apart anyway for other work it would be worth considering swapping it out for a heavier duty one for peace of mind.
