§ 02 / About this part

What it is

The MOTO-MASTER REAR SPROCKET 428 51T BL, sprockets. Stocked by Iron Offroad, the UK MX hard parts specialist.

This component sits on your rear hub and manages the final drive. This specific pitch is standard for small-bore machines and youth racers. Replace it when teeth begin to hook or show significant thinning to avoid chain derailment. Adjusting the tooth count allows you to dial in the power delivery for specific track conditions or terrain. Pair this with a new chain to prevent premature wear on the fresh teeth. The 7075-T6 construction sheds unsprung weight compared to steel alternatives. Use new sprocket bolts and thread lock during installation to ensure everything stays tight.

§ 05 / About Iron Offroad

Iron Offroad

Iron Offroad is the off-road sibling of Iron City and Iron stable — this is a UK shop for motocross, enduro, and trail-bike hard parts. All fitments live on the site, and listed against MX models KTM, Husqvarna, GasGas, Yamaha, Honda, Kawasaki, Suzuki, and Beta. Pick your bike on the timing-tower. Our USP is in the data, fully enriched to assist with accurate fitting and finding the right part for your bike quickly and easily. 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 & e-moto only. We operate from our huge storage facility in Leeds. Iron Offroad is a trading name of Iron Stable Ltd, registered in Mildenhall — Company No. 17061294. We have a RICH motorcycle history with multiple moto brands the images showing where we came from and our history, the business recently pivoted into hard parts and online retail.
