Cylinder kit Malossi Racing 73ccm – Piaggio Bravo / Boss / SI / Grillo – 10mm

The 73ccm Malossi Racing cylinder with CVF system is an extremely powerful and high-torque kit made from grey cast iron, designed for sport and racing use. It is equipped with a robust piston and 2 piston rings for optimal durability and reliable operation at higher RPM.

With aggressive port timing, 6 transfer ports, and the advanced CVF system, this cylinder feels right at home on the racetrack. The manufacturing quality is very high, and the kit includes all necessary small mounting parts, a gasket set, and installation instructions. An aluminum cylinder head is also included.

This is a premium, high-quality cylinder kit intended for demanding users.

For optimal performance and better internal cooling (and therefore longer service life), the use of a larger carburetor is recommended.

The CVF system (Controlled Volume Filling) means additional channels in the cylinder wall (below the transfer ports). Through openings in the piston (above the piston pin), the mixture is additionally fed into the cylinder, which improves filling and increases performance.

Attention: the engine case must be machined (bored out) for proper installation!
