The cylinder has a close deck structure paired with a redesigned modular head. With this cylinder, the engine benefits from reduced loads on the pistons and bearings , thereby extending its lifespan. Additionally, friction is significantly minimized, resulting in increased engine efficiency, along with a notable reduction in noise and vibrations . The exhaust system accompanying the 100 cc kit is the result of targeted engineering, designed to enhance performance and perfect the fluid dynamics of the new Malossi cylinder. Technical features Cooling: H2O Porting: 7 transfer ports Material:…
