§ 02 / About this part

What it is

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

These main bearings support the crankshaft within the crankcases. They endure constant high-RPM loads and intense heat cycles during a race heat. Replace them during any full strip-down or if you detect lateral play in the crank. Worn bearings cause excessive vibration and can lead to air leaks or total engine failure. Ensure the cases are heated and the bearings are chilled for a proper interference fit during installation. These match OEM specifications for a direct drop-in fitment. Check your workshop manual for specific torque settings when reassembling the cases.

§ 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.
