§ 02 / About this part
What it is
The PROX PISTON KIT ALUMINUM 39.48MM C, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.
This top-end component restores compression in small-bore engines. It sits inside the cylinder and converts combustion into mechanical force. You need this when your current piston shows blow-by or exceeds service hours. The C-sizing is specific for cylinders with slight wear or those nearing the end of their plating life. It matches OEM 452.30.007.000 for a direct swap. Always check your ring end gap before final assembly. Ensure the arrow on the crown points toward the exhaust port to avoid snagging rings. Clean the bore thoroughly with solvent before fitting.
