§ 02 / About this part

What it is

The MOTO-MASTER REAR SPROCKET 420 46T BK, sprockets. Stocked by Iron Offroad, the UK MX hard parts specialist.

This component mounts directly to your rear hub to manage final drive delivery. Machined from 7075-T6 aircraft-grade aluminium, it significantly reduces unsprung weight over standard steel units. Replace your sprocket when the teeth show signs of hooking or thinning to prevent chain jump. Pair this with a new chain to avoid premature wear on the fresh teeth. Always use new sprocket bolts and medium-strength thread lock when mounting to the hub. Verify chain slack and wheel alignment after torquing the axle nut. This is a critical service item for any race-spec MX or enduro build.

§ 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.
