§ 02 / About this part

What it is

The MOTO-MASTER REAR SPROCKET 520 50T BL, sprockets. Stocked by Iron Offroad, the UK MX hard parts specialist.

Machined from 7075-T6 aluminium, this component reduces unsprung weight at the hub. It uses a standard 520 pitch for MX and enduro bikes. You need a replacement when teeth begin to hook or show significant thinning. Adjusting the tooth count lets you tune your bike for specific track conditions or tighter trail sections. Always install a fresh chain when fitting new drive components to avoid rapid wear. Ensure you use new mounting bolts and torque them to OEM specifications. This part provides a direct fit to your hub for consistent power transfer.

§ 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.
