§ 02 / About this part

What it is

The PARTS UNLIMITED OEM REPLACEMENT STARTER / NATURAL|SILVER / YAMAHA, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This unit mounts directly to the engine cases to engage the flywheel. Starters often fail after repeated heat cycles or water ingress during deep crossings. This component matches the fitment of OEM 5UM-81890-00-00 and 5UM-81890-10-00. Ensure your battery is fully charged before testing the new unit. Check the starter bendix and crown gear for wear while the motor is removed. It is a direct bolt-on replacement for your bike. Clean the mounting surface thoroughly to ensure a solid earth connection. Inspect the wiring terminals for corrosion to maintain maximum current flow.

§ 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.
