PROX Forged Piston (manufacturer part number 01.7324.C) designed for modifications and refurbishments on Cross motorcycles. Made from forged aluminum and machined to a cone shape, this oversized piston C maintains a diameter of 83.97 mm for precise replacement and compliance with original equipment specifications. Supplied in a kit with the rings, it allows for a clean reassembly of the cylinder head and reliable clearance checks.

Suitable for the listed 300 cm3 displacements, it targets riders looking for a robust wear part to maintain the sealing of the combustion chamber and the consistency of compressions. Its forged construction minimizes the risk of ovalization under intensive riding conditions while staying within the standard compression indicated by the manufacturer.
