§ 02 / About this part

What it is

The PROX PISTON KIT ALUMINUM 83.50MM +0.50MM, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This 0.50mm oversize kit is required when your cylinder bore is damaged or worn beyond standard limits. It allows you to bore out the barrel to a fresh surface rather than replacing the entire cylinder. It cross-references with OEM part 5UH-11631-00-C0. Machining the cylinder to match this specific diameter is necessary before installation. This kit includes the rings, wrist pin, and circlips. Oversize pistons are a cost-effective way to restore a high-hour engine to full health. Ensure your machinist has the piston in hand to achieve the correct clearance for your specific bike.

§ 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.
