Hardened steel construction extends service life when riding in abrasive UK mud. This component mounts to the hub and drives the wheel. This material suits trail and hard enduro use where durability outweighs marginal weight savings. Replace this part if the teeth show signs of hooking or thinning. Install this alongside a new chain to prevent premature wear. Use new bolts and a medium-strength thread lock during assembly. Ensure your wheel is aligned correctly to maintain a straight chain line and reduce friction.

§ 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.
