Cylinder kits - cylinders

The most powerful cylinder kit ever produced by Malossi: over 32 HP at 14,000 RPM. With its large displacement, this kit is exclusively for liquid-cooled motorcycles. Specifically designed for top-level racing, it features the latest evolution of Malossi’s iconic 7-port technology. The standout feature is the support provided to the main rear transfer ports through the use of two ports opposite the exhaust. The cylinder has a close deck structure paired with a redesigned modular head. The head is designed to enter the cylinder’s combustion chamber, safeguarding the nickel coating in case of…

After being a protagonist for 30 years, the everlasting Ø 61 cast-iron cylinder kit, art. 31 4093, updates! Constantly refined over the years, the legendary Ø 61 has now a new code, after undergoing further upgrade concerning above all the main and rear transfer ports. It is the one and only cylinder kit of its kind using an o-ring as sealing gasket between head and cylinder, in order to guarantee better sealing and heat dissipation. By improving torque at low RPMs, this cylinder kit further increases performance. With this development Malossi technicians went beyond all expectations once…
