§ 02 / About this part

What it is

The PROX PISTON KIT FORGED 87.96 MM A, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

This forged piston kit is the primary component for your next top-end service. The A-size is engineered for fresh bores or cylinders with negligible wear. Forged construction offers increased strength for high-load race or hard enduro use. 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 demanding conditions. It matches the original factory specifications for fit and performance.

§ 05 / About Iron Offroad

Iron Offroad

Iron Offroad is the off-road sibling of Iron City and Iron Stable — a UK shop for motocross, enduro, and trail-bike hard parts. Every fitment lives on the site, listed against KTM, Husqvarna, GasGas, Yamaha, Honda, Kawasaki, Suzuki, and Beta. Pick your bike on the timing-tower. Our USP is the data: fully enriched fitment so you find the right part for your bike quickly and get it fitted accurately. 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 and e-moto only. We operate from our storage facility in Leeds. Iron Offroad is a trading name of Iron Stable Ltd, registered in Mildenhall — Company No. 17061294. The business has a rich motorcycle history across multiple moto brands — the photos show where we came from — and recently pivoted into hard parts and online retail.
