The legend lives on. MALOSSI, like POLINI, belong to the Old School. Classic tuning cylinders made of cast iron. A real individualist, gets movin' through both direct intake as well as the original crankcase intake. A real speed freak, delivers an adrenaline powered performance.
Depending on your needs, delivered either with casing or cylinder intake with closed plate. Equipped with the patented MALOSSI CVF II porting system, newly designed cylinder head, effective pinch surface and o-ring gasket, MALOSSI offers everything that a powerful cylinder should have.
Conclusion: An ideal plug and play cylinder with a max bore of 57.7mm. Depending on your needs, reeds or disc valve compatible. Get goose bumps when you hear the name MALOSSI or need more speed? This one's for you! If this still doesn't turn you on, then grab your mill and enlarge the channels, rework the combustion chamber and optimize with the right sized GRAND-SPORT race pistons.
Info: MALOSSI manifold size ends at 24/25mm. If you want more, you'll have to get busy. The only opportunity you'll have using a disc valve in a Vespa V50/PV/ET3, is a carburettor starting at the 30mm range and use a PARMAKIT manifold or it's counterpart from FALC RACING.
