§ 02 / About this part

What it is

The RENTHAL SPROCK R 520 51T BK UL SC, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This aluminium rear sprocket is designed for riders prioritising weight reduction and throttle response. It mounts to the rear hub and works with a 520 chain. The CNC-machined alloy reduces unsprung weight, helping your suspension react faster over rough terrain. Replace this sprocket when the teeth show visible wear or hooking to avoid snapping a chain. It features mud grooves to clear debris from the contact area. Ensure your rear wheel is correctly aligned after fitting to prevent uneven wear. Use new sprocket bolts and torque them to spec to ensure a secure fitment on your bike.

§ 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.
