§ 02 / About this part

What it is

The PROX CRANKSHAFT BEARING, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This bearing supports the crankshaft within the engine cases. It is a critical component for your bottom-end, handling high rotational speeds and combustion loads. Over time, heat and debris cause pitting on the races, leading to audible noise and crank play. Replace these bearings during any major engine service or when splitting the cases. This part is designed to meet OEM specifications for fitment and load ratings. Ensure the cases are heated correctly for a smooth installation into the bore. Proper seating is vital to prevent premature wear and maintain engine balance.

§ 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.
