PROX Forged Piston – Manufacturer Ref: 01.7393.A
Designed for off-road riders and the maintenance of high-performance 2-stroke engines, this PROX forged piston offers a robust construction made from a specific aluminium alloy. Intended as a direct replacement for the original equipment, it is suitable for cross/enduro configurations where piston reliability is paramount. The patented surface treatment reduces friction in the cylinder for cleaner operation and more consistent power delivery.
Designed to withstand the demands of motocross, this piston fits into engine overhaul operations and high-performance kits. Its finish and design facilitate installation on the cylinder side and compatibility with standard rings and pins for this diameter.
