§ 02 / About this part

What it is

The PROX PISTON KIT ALUMINUM 85.25MM +0.25MM, top end. 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 +0.25mm 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.

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.
