§ 02 / About this part

What it is

The PROX PROX PISTON KIT KX250, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This kit restores compression and engine efficiency. Regular maintenance is vital to prevent skirt fatigue and ring failure in high-performance two-strokes. Replacing the piston at the recommended hour interval prevents catastrophic failure and cylinder bore damage. It includes the rings, gudgeon pin, and circlips. Always check ring end gap before installation. Clean the power valve assembly while the cylinder is removed to ensure smooth operation. Lubricate the small-end bearing with fresh oil during your rebuild. Follow the specific break-in procedure to ensure the rings seat correctly against the bore.

§ 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.
