Product details :

Features

PROX Forged Piston (manufacturer ref: 01.7223.C): an aluminum piston designed to replace the original part on the relevant 125 cm³ engines. Designed for standard fitting, it maintains the original geometry with a domed head to respect the chamber volume and stroke specified by the manufacturer.

Diameter: Ø 53.960 mm (oversize letter C)
Compression: Standard
Material: Aluminum
Specificity: Domed head

This piston is aimed at motorcyclists looking for a replacement part that is true to the original for top-end engine restoration. It is suitable for off-road (cross) as well as road (roadster) use, depending on the engine configurations compatible with this diameter.

Associated part references: ring 260343, pin 032026, circlips CP1510, needle cage 400413 — these references facilitate verification and assembly during cylinder reassembly.

Common compatibilities: TM RACING MX 125 (2024), EVO-SET XC125R (2015), TM RACING EN 125 FI (2024). Before purchase, check the oversize measurement and tolerances of your cylinder to ensure correct fitting.
