Malossi MHR TEAM aluminum thermal unit D 50 77cc dismountable head AM6

The Malossi MHR TEAM Ø 50 cylinder kit is a high-quality and high-performance product, ideal for riders who want to participate in National and European Trophies.

Made with high-quality materials, such as a special alloy of aluminum with a high percentage of silicon and titanium, it guarantees high resistance to deformation at high temperatures.

Thanks to a special heat treatment, the cylinder kit maintains its mechanical and dimensional characteristics constant up to temperatures of 250°C.

The machining operations, carried out with CNC machines, ensure very precise dimensional and shape tolerances.

The inner surface of the cylinder is coated with silicon carbides on a nickel matrix, which gives the cylinder kit a very high hardness and remarkable wear resistance.

The exhaust and transfer diagrams have been specifically designed for competition, with a significant commitment from Malossi technicians.

The piston, made with a special alloy with a high percentage of silicon, guarantees resistance to heat and deformation.

The external tin coating reduces the friction coefficient.

The piston structure is reinforced to withstand the stresses imposed by competition, but at the same time it is lightweight to reduce inertia forces.

The ring is made of high-strength spheroidal graphite cast iron, with a hard chrome anti-wear coating.

The detachable Malossi head is specifically designed to ensure the dissipation of heat generated by a high-power engine.

Made of special heat-treated aluminum alloy with a high silicon content, it is directly fixed to the cylinder barrel and is in contact with the cooling liquid on its entire outer surface, ensuring a high heat exchange surface.

The head is free to follow the cylinder's expansions thanks to its position independent of the outer walls.

The combustion chamber is made with CNC machines to ensure precise dimensional and shape tolerances.

The detachable head system is completed with a cover that ensures the sealing of the cooling liquid.

The combustion chamber has been specifically designed for use in the Scooter Speed Trophy and Scooter Cross Trophy.
