Wide range of cylinder base gaskets allow for varying compression ratios. Supplied with all necessary parts.
CYLINDER KIT MHR modular head
The new MHR MODULAR-HEAD CYLINDER KITS are the natural evolution of the MHR MALOSSI line. The result of the research of its engineers, they have been a decisive factor in the victories of the official national and European teams in the cross and speed trophies. Malossi is happy to be able to guarantee that all riders taking part in the coming season National and European Trophies will have a product offering excellent quality and performance.
MHR means MALOSSI HYPER RACING, which says it all. This series has the advantage of being engineered using MALOSSI‘s extensive racing experience. A production series that meets their claim to fame. MHR is a high end racing cylinder made of aluminum (good heat defl ection). Hard chromed piston race, performance pushed up to 16 respectively 24 horsepower, 6 transfer ports and max rpm‘s of circa 15,000. Should be driven with 12mm crankshaft. Motor periphery, such as exhaust/variomatic/ carburetor must be compatible with MHR, respective, Evolution accessories.
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 nickel matrix with heat treatment that guarantees extreme hardness (around 600 HV0, 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.
