§ 02 / About this part

What it is

The MOTO-MASTER REAR SPROCKET 520 43T BK, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This rear sprocket mounts directly to your rear hub to manage final drive power. It features a hardened steel outer ring for maximum service life and a lightweight aluminium inner carrier to reduce unsprung weight. Replace this component when teeth show signs of hooking or thinning. Adjusting the tooth count allows you to re-gear your bike for specific track conditions or terrain. Always install using new sprocket bolts and appropriate thread lock. Ensure your chain tension and wheel alignment are correct to prevent uneven wear across the drive train. This hybrid construction offers a balance between durability and rotational mass.

§ 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.
