§ 02 / About this part

What it is

Moto-master rear sprocket 428 49T to fit Suzuki RM 85 17/14 (2019–2023); Suzuki RM80 (1982–1985, 1989–2001); Suzuki RM85 (2002–2018); Suzuki RM85L (2003–2017); Yamaha YZ80 (1993–2001); Yamaha YZ80LW (1994–2001); Yamaha YZ85LW (2002–2026); Yamaha YZ85SW (2002–2018, 2023–2026); Yamaha YZF-R1S 1000 ABS (2018).

This steel component sits on your rear hub and handles the final drive output. Steel construction is the standard for riders facing abrasive UK mud or high-mileage enduro loops. It outlasts aluminium variants significantly. Replace this part when you notice the teeth hooking or thinning. Always fit a new chain and front sprocket simultaneously to prevent premature wear on your new drive components. Ensure your rear wheel is aligned correctly to avoid uneven side-loading. This part matches OEM fitment dimensions for a direct swap during your drivetrain service. It provides the durability needed for heavy-duty trail use.

§ 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.
