§ 02 / About this part

What it is

The PROX PISTON KIT ALUMINUM 90.00MM +1.00MM, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This piston kit sits in the cylinder and is designed for engines that have been bored out to 90.00mm. It restores compression and performance to your top-end. Replace this component at the recommended hour interval to avoid fatigue and potential cylinder damage. The kit includes the piston, rings, gudgeon pin, and circlips required for a full service. Professional boring and honing of your cylinder are required to match this specific +1.00mm size. This kit provides a reliable seal and restores the compression needed for peak engine 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.
