Malossi cast-iron cylinder kits: the best balance between component performanceand 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. 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 turbolence combustion chamber Compatible with: - Aprilia: SR 50 Min.AC 94-_S - Mbk: Booster 50 euro 0-1_S, Booster 50 euro 2_S, Stunt 50 euro 0-1_S, Stunt 50 euro 2_S - Yamaha: BW's 50 euro 0-1_S, BW's 50 euro 2_S
