Derbi Terra 125 [2007-2013] - H2O cylinder-piston kit - Ø67mm

MALOSSI H2O cylinder-piston kit with Ø 67 mm

This cylinder-piston kit from MALOSSI is intended for the Derbi Terra 125 built between 2007 and 2013. The design combines a precisely machined cylinder with a weight-reduced, reinforced super-compact piston and coordinated piston rings.

Cylinder and heat dissipation

• Bore: Ø 67 mm
• Compression ratio: 12:1
• Piston-cylinder fit: 0.05 mm
• Machining on high-precision CNC machines
• Newly calculated, extra large heat exchange surfaces

The cylinder is made of a high-silicon, refined and hardened aluminum alloy. Its inner liner has a silicon carbide coating on a galvanic nickel matrix. Cross-smoothing in two diamond steps ensures machining within tight tolerances.

Pistons and piston rings

The super-compact piston with three segments is made from a special aluminum-silicon alloy with low thermal expansion. Addition of tin on the sliding surfaces complements the material design. The CNC machining, the reinforced design and extra large heat exchange surfaces are tailored to the mechanical and thermal requirements.

• 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 high mechanical strength

Vehicle assignment

Suitable for the Derbi Terra 125 in the entire model year range 2007 to 2013.
