PROX Forged Piston — Manufacturer's ref: 01.3338.A
Designed for the refurbishment of the top end of motocross engines, this PROX forged piston is made from aluminium and is supplied in oversize A for a bore of Ø 76.96 mm (Ø 76.960 mm). Intended for engine preparations and revisions, it fits models on the applicability list, notably the SUZUKI RM-Z 250 (2007-2009) in 250 cm³.
Raw part for maintenance or rebuilding: it allows for the replacement of a worn or damaged piston during a bore refurbishment. For a complete refurbishment of the top end, ensure you have the appropriate segmentation and sealing references: replacement segments 260063, clips CP1612C, and top end gasket set 603310.
Before installation, check the bore, the piston-to-wall clearance, and follow the manufacturer's recommendations for installation and running-in. This reference is aimed at riders and mechanics looking for a robust part for the restoration of the engine block in motocross use.
