Aprilia RS 125 GP Replica [2022] - H2O cylinder-piston kit - Ø67mm

Malossi H2O cylinder-piston kit with Ø 67 mm

The Malossi H2O cylinder-piston kit is intended for the Aprilia RS 125 GP Replica from 2022. Cylinders and pistons are machined on high-precision CNC machines or CNC machines. The piston-cylinder fit is 0.05 mm.

Cylinders and heat balance

• Bore: Ø 67 mm
• Material: high-silicon, refined and hardened aluminum alloy
• Inner liner with silicon carbide coating on a galvanic nickel matrix
• Cross-smoothing in two diamond steps while maintaining very tight tolerances
• Recalculated and extra large heat exchange surfaces

The combination of precise CNC machining, defined fit and large heat exchange surfaces characterizes the technical design of the cylinder.

Pistons and piston rings

The weight-reduced and reinforced super-compact piston has three segments. It consists of a special aluminum-silicon alloy with low thermal expansion. A tin additive is used on the sliding surfaces. The piston also has extra large heat exchange surfaces.

• First compression ring made of nitrided and chrome-plated steel
• Second piston ring made of special steel
• Three-piece oil scraper made of alloyed and chrome-plated special steel
• Special piston rings with extremely high mechanical strength
