§ 02 / About this part

What it is

Renthal front sprocket 520 13T to fit Honda CRF250R (2018–2021); Honda CRF250RX (2019–2021).

This component sits on the gearbox output shaft to drive your final transmission. CNC machined from case-hardened steel, it handles the high torque loads of MX and enduro. Replace this part when teeth show visible hooking or thinning. Swapping tooth counts allows you to tune your power delivery for specific tracks. Dropping a tooth adds snap for tight technical sections while adding a tooth increases top-end for fast open trails. Always install with a fresh lock washer or circlip. Match this with a new chain and rear drive gear to ensure even wear across the entire system.

§ 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.
