PROX Forged Piston – Manufacturer Ref. 01.6606.B

Designed for cross and roadster engines, this PROX piston is forged from a specific aluminum alloy. Its design aims to limit internal friction and ensure mechanical strength suitable for the demands of large displacement engines. Ideal for engine refurbishment operations or replacement during an oversize re-boring.

• Diameter: Ø 99.960 mm (oversize B)
• Compression: Standard
• Material: Forged aluminum
• Segments: supplied in a segment kit
• Applications: cross / roadster, compatible with listed models

This piston will provide the expected robustness for demanding off-road or road use, while remaining compliant with the original compression ratio. Its finish and dimensional tolerances are suitable for cylinders re-bored to size B. Installation is recommended by an experienced mechanic to ensure proper piston/cylinder head clearance and lubrication system.
