The Malossi MHR Ø 63 thermal unit is an innovative product designed to offer optimal performance and durability.
The cylinder is made of high-strength aluminum alloy, with a nickel-chrome coated barrel to ensure constant heat exchange.
Its aerodynamically profiled fins allow for efficient cooling.
The transfer ports have been completely revised and updated, with 7 ports to achieve the best fluidodynamic performance.
The connection to the exhaust is simple and sturdy, avoiding loosening or rotation problems.
The connection with the cylinder head is made with high precision, ensuring adjustable compression thanks to a set of multi-thickness gaskets.
The piston is made of an innovative material that provides lightness and corrosion resistance, promoting cooling of the combustion chamber.
The head features profiled cooling fins to optimize heat flow and a hemispherical combustion chamber for high turbulence combustion.
High temperatures are regulated by a depression chamber duct that allows for proper wall cooling.
It is important to use fuel taps with increased flow rate.
