MHR REPLICA CYLINDER KIT The MHR Replica line of cylinder was created especially for the International Scooter Trophy - 70cc Automatic Class. These cylinder kits were designed to guarantee maximum performance in this category, while at the same time assuring extremely long product life. In order to guarantee these special characteristics, Malossi MHR Replica cylinder kit have pistons with two chrome-plated rectangular segmants and a compression ratio of 13.8:1, plus torque value of 7.35 N.m. (o.75 Kgm) at 8.000 rpm and power of 6.6 Kw (9 C.V.) at 8.500 rpm. The MHR line is the results of…

The most powerful thermal unit ever produced by Malossi: over 32 HP at 14,000 RPM. With its large displacement and flanged design, this kit is exclusively for liquid-cooled scooters. 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, combined with the advantage of eliminating the space taken up by the through-studs, which are now shorter and positioned externally. This allows full utilization of the…

Vespa ET3 125 Cylinder THE NEW LEGEND Malossi is proud to introduce to its public the total renewal of a real legend, one of the most long-lived and successful projects ever linked to our trade mark: the new and amazing cylinder for Vespa ET3 125. This time wholly aluminium made . The story of this cylinder kit starts in 1982 when, for the first time in a cast iron cylinder with this ring, an oring is used as seal gasket between head and cylinder: a refined solution representing so far the state of the art. Malossi has taken a blank paper to redesign its project, drawing it up new from the…

CYLINDER KIT MHR TECHNICAL FEATURES CYLINDER Material: special aluminium alloy with high percentage of silicon and titanium that guarantees exceptional strain strength even at high temperatures. Heat treatment: special quenching and stabilizing treatment that gives the material increased toughness and strength, guaranteeing that mechanical and size specifications will remain unaltered for temperatures of up to 250 °C. Chip-forming machining: carried out on NC machining centres with extremely-limited size and shape tolerance (roundness, perpendicularity). Inner surface coating: effected using…
