Cylinder Kit w/Head, Malossi 47mm MHR Big Bore 70cc for 50cc 2-Stroke Piaggio, Gilera Scooters

47mm Malossi 70cc MHR Big Bore Cylinder Kit for 50cc 2-Stroke Air-Cooled Piaggio, Derbi, Gilera Scooters

CYLINDER SPECIFICATIONS:

• Bore: 47mm
• Wrist Pin: 12mm
• Displacement: 70cc
• 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 silicon carbide on a nickel matrix with heat treatment that guarantees extreme hardness (around 600 HVO, 1/5) and excellent resistance to wear.
• Internal machining of cylinder: using special machines that allow a degree of finish on the cylinder barrel walls whose roughness corresponds with the angles set at the design stage (grinding process using special stone).
• Port and exhaust diagrams: designed and manufactured especially for racing. The definition of the port and exhaust diagrams has requested considerable effort on the part of our engineers both on engine test stands and the circuits on which the trophy is held.
