§ 02 / About this part

What it is

The MOTO-MASTER REAR SPROCKET 520 40T, sprockets. Stocked by Iron Offroad, the UK MX hard parts specialist.

This steel component sits on your rear hub and handles the final drive output. Steel construction is the standard for riders facing abrasive UK mud or high-mileage enduro loops. It outlasts aluminium variants significantly. Replace this part when you notice the teeth hooking or thinning. Always fit a new chain and front sprocket simultaneously to prevent premature wear on your new drive components. Ensure your rear wheel is aligned correctly to avoid uneven side-loading. This part matches OEM fitment dimensions for a direct swap during your drivetrain service. It provides the durability needed for heavy-duty trail use.

§ 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.
