§ 02 / About this part

What it is

The RENTHAL SPROCKET F 520 13T SC, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This countershaft sprocket is the primary drive point for your bike's transmission. Machined with mud grooves, it prevents dirt packing that can lead to snapped chains or damaged output shaft seals. It is a standard service item that should be replaced alongside your chain and rear sprocket to ensure even wear across the drivetrain. Check the splines for any play before securing the sprocket with the factory nut or circlip. This 13T size offers a balanced gear ratio suitable for most MX and cross-country tracks in the UK.

§ 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.
