This component is the final link in your drive train, transferring power from the chain to the hub. The 428 pitch is common on small-bore bikes and youth racers where weight and friction reduction are vital. Steel construction ensures a long service life in abrasive UK mud compared to pure aluminium alternatives. Replace your drive components as a complete set to prevent premature wear on the new teeth. Check your chain tension and alignment after every wash to maintain the profile. This is a model-specific fitment designed for standard hubs.

§ 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.
