§ 02 / About this part

What it is

ProX crankshaft bearing and seal kit to fit Kawasaki KX500A (1983–1984); Kawasaki KX500B (1985–1986); Kawasaki KX500C (1987); Kawasaki KX500D (1988); Kawasaki KX500E (1989–2004).

This kit handles the heavy lifting in your lower engine. These bearings seat directly into the crankcases to support the crankshaft. Over time, heat and high RPM lead to play or noise. Worn seals cause air leaks and lean running which can ruin a fresh top-end. Replace these during any full engine rebuild to ensure a smooth stroke and reliable primary compression. Installation requires splitting the cases and usually involves heat cycles for a proper interference fit. These components meet OEM specifications for fit and tolerance. Keep your crank spinning true and your crankcase pressure sealed.

§ 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.
