§ 02 / About this part

What it is

The PROX PISTON KIT ALUMINUM 82.50MM +0.50MM, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This oversized piston is designed for rebuilds where the cylinder has been bored out by 0.50mm. It restores engine displacement and compression after a cylinder repair. Replacement is essential for maintaining power and preventing mechanical failure. Confirm your cylinder has been machined to the correct 82.50mm specification. Check the ring end gap before fitting. Ensure the circlips are properly seated in the grooves. This kit includes the rings, gudgeon pin, and circlips.

§ 05 / About Iron Offroad

Iron Offroad

Iron Offroad is the off-road sibling of Iron City and Iron stable — this is a UK shop for motocross, enduro, and trail-bike hard parts. All fitments live on the site, and listed against MX models KTM, Husqvarna, GasGas, Yamaha, Honda, Kawasaki, Suzuki, and Beta. Pick your bike on the timing-tower. Our USP is in the data, fully enriched to assist with accurate fitting and finding the right part for your bike quickly and easily. Brands you'd find on a paddock workbench; pads, sprockets, plastics, fork seals, cables, gaskets, bars, the things that actually wear out. Road-bike kit, scooter parts, and quad gear sit elsewhere. Dirt & e-moto only. We operate from our huge storage facility in Leeds. Iron Offroad is a trading name of Iron Stable Ltd, registered in Mildenhall — Company No. 17061294. We have a RICH motorcycle history with multiple moto brands the images showing where we came from and our history, the business recently pivoted into hard parts and online retail.
