§ 02 / About this part

What it is

The RENTHAL SPROCKET F 520 15T, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This component sits on the gearbox output shaft to drive your final transmission. CNC machined from case-hardened steel, it handles the high torque loads of MX and enduro. Replace this part when teeth show visible hooking or thinning. Swapping tooth counts allows you to tune your power delivery for specific tracks. Dropping a tooth adds snap for tight technical sections while adding a tooth increases top-end for fast open trails. Always install with a fresh lock washer or circlip. Match this with a new chain and rear drive gear to ensure even wear across the entire system.

§ 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.
