§ 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 front sprocket sits on the countershaft to transfer engine power to the drive chain. Hardened steel construction provides the durability needed for the high-speed rotation at the gearbox output. Choosing a different tooth count allows you to fine-tune your bike for specific track conditions. Replace this part when the teeth become pointed or hooked to avoid damaging your chain. Check the countershaft splines for wear during the swap. Always ensure the sprocket is locked tight with the correct tab washer or bolt to maintain drive integrity.

§ 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.
