§ 02 / About this part

What it is

The PROX PISTON KIT FORGED 101.00 MM +1.00MM, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This forged component is for engines requiring a rebore due to cylinder damage or high mileage. It sits in the top-end and provides a fresh sealing surface for restored compression. Forged construction handles the increased heat and stress of a larger displacement. This oversize kit requires professional machining of your cylinder to match the specific diameter. Replace during a full top-end refresh to maintain engine integrity. Always verify your machinist has the part in hand before they cut the bore to ensure an exact fit.

§ 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.
