§ 02 / About this part

What it is

Moto-master front sprocket 520 12T to fit Sherco SE-R250 (2021–2022); Sherco SE-R300 (2021–2022); Sherco SE250 (2021–2024); Sherco SE300 (2021–2025); Sherco SEF-R250 (2021); Sherco SEF-R300 (2021–2022); Sherco SEF250 (2021–2024); Sherco SEF300 (2021–2025).

This countershaft sprocket mounts to the gearbox output shaft. It is the primary drive component for your 520 chain. High torque and abrasive soil cause the teeth to hook over time. A 12T configuration provides maximum low-end grunt for technical climbs. Replace this part when you fit a new chain to prevent premature wear. Clean the output shaft splines thoroughly during the swap. Check the retaining clip or bolt for security. This steel component matches OEM specifications for fit and durability. It is a standard service item for any rebuild.

§ 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.
