§ 02 / About this part

What it is

The PROX PISTON KIT ALUMINUM 44.46MM B, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This B-size piston kit is designed for small-bore engines requiring precise tolerances. It cross-references with OEM 13001-1630. The B-sizing accounts for slight cylinder wear, providing a tighter fit than a standard A-piston. It sits in the top-end and is a critical service item for maintaining peak performance. Replace this kit at the recommended hour interval to avoid catastrophic failure. The package includes the piston, rings, pin, and circlips. Measure your cylinder bore with a dial bore gauge to confirm B-size is the correct fitment. Always use fresh gaskets for the head and base.

§ 05 / About Iron Offroad

Iron Offroad

Iron Offroad is the off-road sibling of Iron City and Iron stable — this is a UK shop for motocross, enduro, and trail-bike hard parts.

Our USP is in the data, fully enriched to assist with accurate fitting and finding the right part for your bike quickly and easily. 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 & e-moto only. We operate from our huge storage facility in Leeds. Iron Offroad is a trading name of Iron Stable Ltd, registered in Mildenhall — Company No. 17061294. We have a RICH motorcycle history with multiple moto brands the images showing where we came from and our history, the business recently pivoted into hard parts and online retail.
