CAST-IRON CYLINDER KITS Malossi is glad to present the new line of cylinder kits which have been designed for the latest generation scooters. They are unique tools able to defeat the traffic black-out of our cities. They are highly reliable and they have an exceptional torque. They have been studied to support a prolonged stress and can offer high accelerations even on highly pendent roads. They do not know neither fatigue nor wear. Technical data Material: cast iron Cooling: air Bore: 45,5 mm Stroke: 39,3 mm Capacity 64 Compression ratio: 10,5:01 Timing system: 7 ports Cylinders made of…

Fun without complications (6 transfer ports – 2 ring piston) Malossi cast iron thermal units, the first and simplest step to modifying your motorcycl’s engine, are the best choice for continued use of the exhaust system of an approved series or type . For these thermal units, the elevated feature of durability of cast iron is combined with the almost manically high quality standards of Malossi, one of the few companies to demand the most from even this class of thermal units. Into this is inserted the most rigid selections for the joining of the cylinder and the piston, strictly maintained…

Technical features 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 stabilising 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 silicon carbide on a…

CAST-I-CYLINDER KIT Ø 63 CYLINDER The cylinder has a bore of 63 mm with a displacement of 178 cc and completely revised internal fluid dynamics. New port mapping allows for a high degree of coupling both with linked sumps and with completely new sumps, and includes a special profiling designed to optimise flow and obtain significant increases in performance, without the need to carry out any additional work on the vehicle. TRANSFER PORTS The transfer ports have a profile designed to correctly orientate the incoming flow and obtain a high degree of turbulence, thus ensuring improved combustion…

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…
