§ 02 / About this part

What it is

The PROX PISTON KIT FORGED 87.98MM C, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This forged piston kit is designed for precise top-end maintenance. It sits within the cylinder bore, converting combustion into mechanical force. The specific letter-coded sizing allows you to match the piston perfectly to your cylinder's current wear state. Regular replacement prevents skirt collapse and maintains peak compression across the rev range. Measure your bore with a micrometer before selection to ensure the correct clearance. During installation, verify the ring end gap and ensure the gudgeon pin circlips are fully seated. This kit includes the piston, rings, pin, and clips for your rebuild.

§ 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.
