§ 02 / About this part

What it is

The MOTO-MASTER FRONT SPROCKET 520 13T, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This drive component sits directly on the output shaft and endures constant torque and abrasive grit. You should replace it when the teeth begin to hook or show visible thinning. Worn teeth accelerate chain wear and sap power from the rear tyre. This steel part is machined to match OEM spline tolerances for a precise fit. Always inspect the lock washer or circlip during your rebuild. If you are adjusting the tooth count for specific track conditions, verify your chain length and swingarm clearance. Changing the front size has a significant impact on your bike's final drive ratio.

§ 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.
