The Malossi 180 H2O cylinder kit was born from years of direct development in competition, on the same scooters for which it was originally designed, the Gilera Runner . It's the component for you if you want to convert a 125cc liquid-cooled 2-stroke engine into a 180cc one. Reliable and robust, it ensures effective thermal dissipation even under prolonged stress, keeping the engine at constant temperature and performance over time. The geometry of the head – completely redesigned with a truncated cone dome with a central spark plug, an enlarged exhaust duct, and a third transfer port open at…

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…

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…

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…
