§ 02 / About this part

What it is

The PROX PISTON KIT ALUMINUM 79.00MM +0.50MM, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

This oversize kit is designed for your next engine refresh when the cylinder bore requires machining beyond standard limits. It sits at the heart of your engine and restores compression lost to wear or heat cycles. The +0.50mm sizing allows you to salvage a scored cylinder rather than replacing the entire barrel. This component cross-references with OEM part 13101-HN5-670. Ensure your machinist verifies the final bore clearance before assembly. Always check ring end gap during installation to prevent binding at operating temperatures.

§ 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.
