§ 02 / About this part

What it is

The RENTHAL SPROCK R 520 48T SI UL SC, sprockets. Stocked by Iron Offroad, the UK MX hard parts specialist.

This rear sprocket sits on the hub to transfer power to the rear wheel. Machined from high-strength aluminium, it significantly reduces unsprung weight compared to steel alternatives, improving your suspension's tracking over rough ground. Mud grooves are integrated into the design to clear grit and debris from the chain rollers, extending the life of your drive train in typical UK conditions. Replace this component when the teeth show visible hooking or thinning. Always install with a new chain to prevent accelerated wear. Ensure your sprocket bolts are torqued to OEM specifications and secured with thread lock.

§ 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.
