The PROX forged piston (Manufacturer reference 01.1417.A) is designed for motocross and enduro riders looking for a reliable replacement part that matches the original equipment. Machined from an aluminum alloy and produced through forging, it offers a robust design suited to the demands of high RPMs and off-road conditions.

• Diameter: Ø 95.96 mm (oversize letter: A)
• Compression: standard 13.5:1
• Material: forged aluminum
• Number of segments: segment kit included
• Designed for a reconditioning equivalent to the original equipment

This piston is suitable for engine preparations requiring a piston replacement in size A. Its forged construction minimizes surface irregularities and provides good mechanical durability over time, which are important factors for reliability in off-road use. Ideal for overhauling 450 cm3 engines, it is particularly compatible with HONDA CRF 450 R, RWE, and RX ENDURO models (2026 vintage).

Always replace while respecting manufacturer tolerances and perform cylinder/clearance fitting checks to ensure a safe and durable installation.
