PROX Forged Piston (ref. 01.4335.C) — designed for motocross engines, these forged pistons are machined from an aluminum alloy engineered to minimize friction and maintain cylinder integrity. They are intended for rebuilds or for those seeking a performance-oriented solution, adhering to the original geometry with standard compression.

• Piston diameter: Ø 76.98 mm (oversize letter C)
• Compression: Standard
• Material: Forged aluminum

The forged piston offers a more compact and homogeneous structure than cast parts, which is appreciated on machines subjected to the typical RPMs and stresses of motocross. The oversize C indicates a diameter larger than the original to fit re-bored cylinders. Installation and wear check are mandatory: adhere to the bore specifications, piston/cylinder clearance, and the manufacturer's installation procedure.

Common compatibilities: SUZUKI RM-Z 250 (2005, 2006) and KAWASAKI KX 250 F (2005). Manufacturer reference: 01.4335.C.
