§ 02 / About this part

What it is

Moto-master rear sprocket 428 51T 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 (2002–2021, 2023–2026).

This part is built for maximum service life in harsh UK conditions. It sits on the rear hub and handles the torque from the chain. Steel construction resists the abrasive effects of mud and sand better than aluminium alternatives. This makes it the standard choice for green-laning or long-distance enduro. Check your chain tension and alignment regularly to prevent uneven tooth wear. Replace this alongside a new chain and front sprocket to ensure the entire drivetrain wears at the same rate.

§ 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.
