§ 02 / About this part
What it is
The PROX PISTON KIT FORGED 87.97MM B, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.
This forged unit is the heart of your top-end rebuild. It sits in the cylinder bore and takes the brunt of every combustion cycle. The B-sizing provides a tighter fit for cylinders that have seen several hours of use and minor wear. Forged parts offer better structural integrity for racing applications compared to cast versions. Measure your cylinder bore accurately before ordering to ensure the correct clearance. Always use fresh gaskets and a new small-end bearing. Orient the rings correctly according to the workshop manual to ensure a proper seal.
