§ 02 / About this part

What it is

The PROX PISTON KIT ALUMINUM 39.47MM B, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This B-size kit provides a slightly larger diameter for cylinders that have seen initial wear. It sits in the top-end, ensuring the piston-to-wall clearance remains within factory specifications. Regular replacement is vital for maintaining compression and preventing blow-by. Check the cylinder for wear patterns before installation. Ensure the ring end gap is verified against the workshop manual. Install the wrist pin clips carefully to ensure they are fully seated. This kit is a standard part of a proactive maintenance schedule for your bike.

§ 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.
