Founded in 1930, Malossi continues to be one of the leading manufacturers of tuning parts for scooters and mopeds. Top quality materials and excellent workmanship are typical of everything made by Malossi.

The Malossi MHR Cylinder Kit 136cc (d=57.5mm) aluminium Vespa Primavera ET3 125cc is a high-end tuning cylinder designed for the race track. Malossi MHR engineers are always trying to redesign and improve cylinder layout. High-quality aluminium (with very hard Nicasil-coating) now replaces the original cast iron, port timings were remapped for impeccable racing performance. The ports are large, the exhaust port is bridged. As you can never go wrong with more displacement, Malossi pushed it up to 136cc. The cylinder provides plenty of torque and unbeatable amounts of hp.
The piston is a high-end Asso piston, with 1 thin, light, wedge-shaped ring with anti-friction coating.
The cylinder head included in the kit is a high-compression cylinder head.
The cylinder was designed for crankshafts with 51mm stroke.
