§ 02 / About this part

What it is

The PROX PISTON RING SET 71.00MM STANDARD, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

Designed for a 71.00mm standard bore, these rings provide the critical seal required for efficient combustion. They sit on the piston to transfer heat and manage oil lubrication. Over time, friction reduces their effectiveness, causing blow-by and power loss. Replace these during a top-end refresh to maintain your bike's performance. Always measure the ring end gap in the bore before final assembly. Ensure all markings face the cylinder head. These are precision-machined to provide a reliable seal under high-load racing conditions.

§ 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.
