The most powerful cylinder ever produced by MALOSSI: over 32 hp at 14,000 rpm. Designed exclusively for liquid-cooled scooters with its large displacement and flanged design, this kit is a pinnacle of racing performance.
Specially developed for top-level racing, it combines the latest evolution of MALOSSI's iconic 7-port technology. A notable feature is the innovative support of the main rear transmission ports by two additional ports opposite the exhaust. This, combined with the elimination of through bolts, makes the most of the extra space provided by the flanged design.
The cylinder has a close deck structure combined with a redesigned modular head. The head is strategically designed to enter the combustion chamber of the cylinder, protecting the nickel coating from possible detonation.
Installation of this thermal unit requires modifications to the RC-ONE engine block:
- Bore area: To accommodate a crankshaft with increased stroke and a longer connecting rod (specifically, a 47 mm stroke and a 100 mm connecting rod).
- Flowing: Coil ports flowing is necessary.
Volumes and flows have been carefully optimized to release the full potential of this cylinder. No compromises: a carburetor between 30 and 34 mm is essential. For optimal synergy and maximum performance on the road, the 100cc kit must be combined with our crankshaft, which has an updated 100 mm connecting rod.
With this cylinder, the engine benefits from reduced stresses on the pistons and bearings, extending its life. In addition, friction is significantly reduced, leading to increased engine efficiency, along with a noticeable reduction in noise and vibration.
The exhaust system that accompanies the 100cc kit is the result of focused engineering, designed to improve performance and perfect the flow dynamics of the new MALOSSI cylinder.
How did we achieve this? By optimizing the exhaust port angle and implementing a custom clutch.
In addition, to ensure an effective connection to the exhaust pipe, we developed an ingenious flange coupling system. This system attaches to the cylinder with three cylindrical head screws and an O-ring seal at the exhaust duct. This simple but very effective solution prevents any leakage from the thermal unit.
