Malossi MHR TEAM aluminum thermal unit D 40,3 LC dismountable head AM6

The Malossi MHR TEAM Ø 40.3 thermal unit is a high-quality and high-performance product, ideal for riders who want to participate in National and European Trophies.

This new thermal unit is the natural evolution of the Malossi MHR line and has contributed to the victories of official teams in cross and speed trophies.

The cylinder is made with a special alloy of aluminum with a high percentage of silicon and titanium, which guarantees great resistance to high temperatures.

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

The machining for chip removal is carried out with very tight dimensional and shape tolerances, guaranteeing high quality.

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

The piston is made with a special alloy with a high percentage of silicon, which guarantees great resistance to heat and dimensional stability with temperature variations.

The external tin coating reduces the friction coefficient.

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

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

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

It is made of a special bonified aluminum alloy with a high silicon content and is directly fixed to the cylinder barrel.

The head is fully bathed on its entire outer surface by the cooling liquid, ensuring a large heat exchange surface.

Being detached from the outer walls, the head can follow the cylinder's expansions.

The combustion chamber is precisely made using numerical control machines, guaranteeing dimensional tolerances to the hundredth of a millimeter.

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.

The Malossi MHR TEAM Ø 40.3 thermal unit is a product of the highest performance and quality level, ideal for riders looking for a reliable and high-performing product for competition.
