§ 02 / About this part

What it is

The PROX PISTON KIT ALUMINUM 71.96MM C, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

This C-size kit is designed for 2-stroke engines where the cylinder bore has expanded through use. It replaces OEM part 546.30.307.400 and restores the tight tolerances required for maximum primary compression. On high-performance 2-strokes, this is a primary consumable that needs regular replacement to prevent port snagging or skirt collapse. This kit includes the rings, pin, and clips. Always check the ring end gap in the cylinder before fitting. Ensure the arrow on the crown points toward the exhaust port during your rebuild.

§ 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.
