§ 02 / About this part
What it is
The PROX PISTON KIT ALUMINUM 66.35MM B, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.
Refresh your two-stroke top-end to maintain peak power. This kit replaces the stock unit to match OEM 548.30.007.300 specifications. Piston skirts wear and rings lose tension over hard race hours. Swapping this out at the recommended service interval prevents bore damage and keeps the engine tight. This specific size accounts for cylinder wear or plating thickness. Check your bore diameter with a micrometer before selection. Ensure the ring gaps are positioned over the locating pins. Always fit a new small-end bearing and gaskets during the rebuild.
