§ 02 / About this part

What it is

The PROX PISTON KIT ALUMINUM 64.75MM +0.75MM, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

This assembly restores compression when your cylinder bore shows wear or scoring. It operates within the cylinder, converting combustion into mechanical force. Use this oversize option after a professional rebore to ensure a precise seal. The kit includes the rings, gudgeon pin, and circlips. Always check your ring end gap before installation. Ensure the arrow on the crown points toward the exhaust port. Lubricate the small-end bearing and pin during assembly. This is a standard service item for high-hour engines to prevent skirt failure and maintain peak power delivery.

§ 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.
