§ 02 / About this part

What it is

The PROX PISTON KIT ALUMINUM 48.46MM B, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This aluminum piston kit is designed for your top-end maintenance. It sits within the cylinder, converting combustion into drive. The B-size grading suits bores with minor wear to maintain compression. This kit matches OEM cross-reference 13001-0744 for a straightforward install. 2-stroke pistons require regular replacement to avoid skirt fatigue and lost performance. Always clean the power valve assembly while the top-end is stripped. Measure your bore accurately with a dial bore gauge to choose the correct size for your rebuild. The kit includes the piston, rings, pin, and circlips.

§ 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.
