§ 02 / About this part

What it is

The PROX PISTON KIT ALUMINUM 78.75MM +0.25MM, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

Restore engine performance with this +0.25mm oversize kit. It is a direct solution for engine wear where a light bore and hone are necessary to clear surface imperfections. This component replaces OEM part 13101-HN5-670 and includes the rings, pin, and clips required for a full refresh. Proper fitment depends on precise cylinder measurement to ensure correct clearance. Clean all oil galleries and the combustion chamber thoroughly before fitting. This kit provides a reliable alternative to standard sizing for high-hour engines.

§ 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.
