Prox Forged Piston kitRef : PRO00268A / 1095192001

PROX Forged Piston (manufacturer part number: 01.1589.050) — designed for roadster engines that require robustness and precision. Machined from an aluminum alloy and produced through forging, this piston offers mechanical durability suitable for thermal cycles and displacement constraints. Its design incorporates a process used by many manufacturers for a good performance/reliability compromise.

• Diameter: Ø 92.50 mm (oversize +0.50)
• Compression: standard 9.5:1
• Material: forged aluminum
• Patented surface treatment to reduce friction in the cylinder
• Delivered in a ring kit

This forged piston is aimed at motorcyclists looking for a replacement equivalent to the original equipment, with a targeted fit for small displacement roadsters. The finish and machining ensure a precise fit in the bore, while the surface treatment helps limit wear and friction between the piston and wall.

Notable compatibility: Honda GB 500 Clubman (PC16), Honda NX 500 Dominator (PD08), and Honda XBR 500 S (PC15) — always check the bore and oversize of your cylinder before installation. Installation and adjustment must remain in accordance with manufacturer recommendations to preserve engine longevity.
