§ 02 / About this part

What it is

The PROX PISTON KIT ALUMINUM 84.00 MM STANDARD, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This standard-size aluminium piston kit is the primary component for your next top-end service. It is engineered for fresh bores or cylinders with negligible wear. Regular replacement prevents skirt collapse and catastrophic engine failure. Measure your bore with a micrometer to ensure the correct clearance before fitting. During installation, verify the ring end gap and seat the circlips firmly in their grooves. This kit provides the necessary compression and sealing for race or trail use. It matches the original factory specifications for fit and performance to keep your bike running at peak efficiency.

§ 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.
