§ 02 / About this part

What it is

The PROX PISTON KIT ALUMINUM 85.50MM +0.50MM, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This piston kit is designed for engines requiring a rebore, cross-referencing OEM part 13101-KCY-670. It sits in the cylinder and restores compression to a worn top-end. The +0.50mm oversized diameter allows you to salvage a worn bore by machining it to this specific size. Replace your piston when the skirt clearance exceeds workshop limits. This kit includes the piston, rings, pin, and clips. Professional boring and honing of your cylinder are required to match this specific piston size. It ensures your bike returns to factory power levels.

§ 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.
