PROX Forged Piston (manufacturer part number 01.6311.C) designed for Cross displacements. Machined from a specific aluminum alloy, this forged piston aims to limit internal friction and ensure consistent performance at the heart of the engine, without altering the original configuration.
This PROX piston is aimed at motocross riders looking for a robust replacement part, precisely machined to fit compatible engine blocks. Its finish optimizes contact with the cylinder while respecting the original specifications in terms of compression. Ideal for engine overhauls where the piston and rings are replaced while maintaining the basic settings.
