PROX Forged Piston designed for high-performance modifications and rebuilds on off-road machines. This aluminum piston, "Flat with hollow" finish, features the necessary dimensions for a reassembly that complies with original specifications with standard compression. Its flat geometry with a central cavity facilitates adaptation in the combustion chambers of 4T cross engines while remaining true to the manufacturer's dimensions.
Ideal for replacing a worn piston during an engine rebuild or for refreshing the top end after long off-road sessions. Check the bore and manufacturer tolerances before installation. Compatible with BETA RR 480 4T models (2024, 2019) listed below and other machines with the same piston size.
