PROX Forged Piston – Ref. 01.6347.B
Designed for motocross use, this PROX forged piston features a CNC machined aluminum construction and a treated skirt finish aimed at facilitating break-in and reducing friction. Delivered as a complete kit, it allows for a clean restoration of the moving assembly for 250 cc displacements equipped with a corresponding bore.
Technical specifications and kit contents:

Its coated skirt aids in the initial break-in and aims to reduce contact wear during the first hours of use — a benefit for engines subjected to off-road conditions.
