PROX cast piston designed for cross mounts in oversize A. Machined from aluminium, it features a domed head and a skirt treated with Mos2 (molybdenum disulphide coating) to reduce friction. The piston has a diameter of Ø 44.45 mm (oversize letter A) and standard compression, suitable for the corresponding bores. The exhaust side skirt is drilled with 2 lubrication holes to ensure oil supply at the critical level of the sleeve.
This piston is intended for cross machines requiring an oversize A. Compatible models include: KAWASAKI KX 65 (2026), SUZUKI RM 65 (2005), and KAWASAKI KX 65 (KX65A) (2021). Before installation, check the cylinder bore, the thickness of the rings, and the manufacturer's tolerances.
