§ 02 / About this part
What it is
The PROX PISTON KIT ALUMINUM 42.95MM A, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.
This A-size kit is for fresh or low-hour cylinders requiring a standard top-end refresh. It sits inside the bore, maintaining the compression required for high-revving small-capacity engines. These pistons face extreme heat and should be replaced according to your race schedule to prevent skirt fatigue. Check the cylinder for any glazing before installation. Ensure the ring gap is within spec to avoid seizing. Orient the piston correctly to ensure the rings do not snag on the ports. This kit includes all necessary components for a standard top-end service.
