The MALOSSI Ø67 H2O 4T cylinder is a thermal component dedicated to liquid-cooled Honda 4-stroke engines. Designed for road/roadster applications, it combines high-silicon aluminum alloy and silicon carbide treatment for a wear-resistant surface and precision honing.

• Material: high-silicon aluminum, silicon carbide treatment
• Bore: Ø67 mm — intended for H2O 4T configurations
• Machining: performed on CNC machines
• Piston-cylinder clearance: 0.05 mm for controlled tolerance
• Improved thermal exchanges for better heat dissipation

The kit includes an ultra-compact 3-segment piston, made of the same aluminum alloy, CNC machined, lightweight, and reinforced to reduce moving masses. The segments are of high strength and chrome-plated, contributing to the sealing and longevity of the thermal assembly.

This part is aimed at tuners and riders looking for a robust base for engine optimization on 125 cc Honda models (e.g., CB125R, CBR125). Installation and adjustments should be carried out by a professional.
