§ 02 / About this part

What it is

The RENTHAL SPROCKET F 520 13T SC, sprockets. 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 — 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.
