§ 02 / About this part

What it is

The MOTO-MASTER FRONT SPROCKET 520 15T, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This countershaft sprocket sits on the engine output shaft to drive your chain. It is a high-wear component that demands regular inspection. Replace it when you notice hooked teeth or a thinned profile to prevent chain damage. Grit and mud accelerate wear here faster than at the rear due to the tighter radius. Adjusting the tooth count is the fastest way to gear your bike for technical wood sections or high-speed desert runs. Clean the splines thoroughly before installation. Always fit a fresh lock washer or circlip and torque the nut to OEM specifications.

§ 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.
