§ 02 / About this part

What it is

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

This 520 pitch aluminium part is designed to reduce rotating mass at the rear wheel. It sits on the hub and handles the final drive load. Aluminium construction offers a significant weight saving over steel. Replace it when teeth show signs of hooking or thinning from use. Always install a fresh chain when fitting to avoid rapid wear. Verify your bike uses the 520 chain size before ordering. Use high-quality bolts and apply thread lock to prevent loosening. It is built for competitive MX and enduro use.

§ 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.
