The MALOSSI MHR Teal Ø40.3 cylinder kit module H20 (manufacturer reference 3112381) is a thermal group designed for the track and intensive riding phases. Made from a high-silicon aluminum alloy, it features heat treatment for hardening and stabilization for dimensional stability up to 250°C. The sleeve receives a silicon carbide coating on a nickel matrix, providing a very hard and wear-resistant sliding surface, while the internal machining aims for a finish suitable for lubrication and longevity.

• Diameter: Ø 40.3 mm
• Material: special aluminum alloy
• Design: decomposable cylinder head, CNC machined combustion chamber
• Machining: tight tolerances, competition-studied opening diagrams

The kit includes a high-silicon alloy piston with a graphite coating and a chrome spheroidal cast iron ring, reinforced components to withstand the stresses of high RPMs. The decomposable cylinder head, liquid-cooled in contact with the sleeve, facilitates thermal dissipation and squish control.
