§ 02 / About this part

What it is

Moto-master front sprocket 520 12T to fit Honda CR125R (2004–2007); Honda CRF250R (2004–2017); Honda CRF250X (2004–2018).

Machined from case-hardened chromoly steel, this 12T sprocket is built for high-torque applications in technical terrain. It sits on the countershaft and provides a shorter gear ratio for better low-end response. Front sprockets wear faster than rear ones due to the smaller circumference and higher rotation speed. Replace this part if you see any hooking to maintain drivetrain efficiency. Ensure the splines are clean and the sprocket is locked down with a fresh tab washer. Check your chain tension after fitting, as the 12T size changes the chain's path over the swingarm slider.

§ 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.
