§ 02 / About this part

What it is

Moto-master front sprocket 520 13T to fit Suzuki RM-Z 450 (2013–2026); Suzuki RM-Z 450 E (2018–2019).

This countershaft sprocket sits on your bike's output shaft to drive the final transmission. It is a high-wear component. Inspect it regularly for hooked teeth or thinning profiles. Abrasive mud and grit accelerate wear during heavy sessions. Adjusting the tooth count alters your bike's final drive ratio for technical terrain or faster tracks. Clean the countershaft splines thoroughly before installation. Fit a new circlip or lock washer to secure the assembly. Pair this with a new chain to prevent premature wear on the fresh teeth. This steel construction matches OEM specifications for fitment and durability.

§ 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.
