§ 02 / About this part

What it is

The MOTO-MASTER REAR SPROCKET 520 51T BK, sprockets. Stocked by Iron Offroad, the UK MX hard parts specialist.

Reducing unsprung weight at the rear hub improves suspension response and acceleration. This CNC-machined aluminium component offers a significant weight saving over standard steel alternatives. It is designed for 520 pitch chains common on modern MX and enduro bikes. Replace your sprocket when teeth show signs of hooking or thinning to prevent premature chain wear. Always use new sprocket bolts and a thread-locking compound during installation. Ensure your rear wheel is aligned correctly to maintain a straight chain line. This part is essential for riders looking to sharpen their bike handling on the track or trail.

§ 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.
