Malossi 70cc Big Bore Cylinder Kit - Vespa Piaggio ET2 50

Malossi 70cc Big Bore Cylinder Kit – Vespa ET2 & Piaggio 50 Unlock significant power gains with the Malossi 70cc Cast Iron Cylinder Kit . Engineered in Italy, this kit provides the perfect balance between high-performance output and long-term daily reliability. It is the go-to upgrade for riders looking to increase torque and top-end speed without sacrificing the durability of their engine. Malossi engineers have optimized the thermodynamics and internal fluid mechanics with fanatical precision. By refining the transfer ports, exhaust timing, and combustion chamber shape, this kit achieves a high level of turbulence, leading to better fuel efficiency and a drastic reduction in exhaust emissions. Key Performance Features Wear-Proof Material: Specialized laminate cast iron construction designed for maximum component life. Enhanced Cooling: Recalculated heat exchange surfaces for superior temperature management. High-Silicon Piston: Includes a lightened and reinforced special aluminum alloy piston for reduced friction. Optimized Compression: High-turbulence combustion chamber designed for maximum efficiency. Comprehensive Model Fitment This kit is a direct fit for 50cc 2-Stroke (Air Cooled) Piaggio engines, including: Vespa Models: Vespa ET2: All Years Vespa LX 50: 2-Stroke Versions Vespa S 50: 2-Stroke Versions Piaggio & Aprilia Models: Piaggio Typhoon 50: (2007-2010) Piaggio LT 50: All Years Piaggio Fly 50: 2-Stroke Versions Aprilia SR50 Motard: (Piaggio Engine Models) Technical Specifications Displacement: 70cc Bore: 47mm Material: Cast Iron Piston Pin: 12mm Machining: NC Machine-Tool finished for precision tolerances Maintenance & Support To keep your Malossi kit running at peak performance, we carry the following replacement parts: Replacement Piston Kit Replacement Piston Rings ?? Safety & Legal Note: Not legal for use in California on pollution-controlled vehicles. This product is intended for off-road/racing use only. Check local laws before installing. Malossi cast-iron cylinder kits: the best balance between component performanceand life of the component. This kit will fit Vespa ET2 and other scooters with a 50cc ET2 Piaggio engine. 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
