§ 02 / About this part

What it is

The PROX PISTON KIT ALUMINUM 66.38MM D, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This piston kit is intended for cylinders that have seen significant service. The D-size diameter provides the necessary fit for bores at the upper limit of wear tolerances. It replaces OEM part 1P8-11631-00 and restores the compression required for competitive performance. The kit contains the piston, rings, pin, and clips. Neglecting piston service intervals can lead to costly cylinder damage. This component sits in the top-end and is critical for the efficiency of your 2-stroke engine. Precise measurement of your cylinder is required to confirm this fitment.

§ 05 / About Iron Offroad

Iron Offroad

Iron Offroad is the off-road sibling of Iron City and Iron Stable — a UK shop for motocross, enduro, and trail-bike hard parts. Every fitment lives on the site, listed against KTM, Husqvarna, GasGas, Yamaha, Honda, Kawasaki, Suzuki, and Beta. Pick your bike on the timing-tower. Our USP is the data: fully enriched fitment so you find the right part for your bike quickly and get it fitted accurately. 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 and e-moto only. We operate from our storage facility in Leeds. Iron Offroad is a trading name of Iron Stable Ltd, registered in Mildenhall — Company No. 17061294. The business has a rich motorcycle history across multiple moto brands — the photos show where we came from — and recently pivoted into hard parts and online retail.
