§ 02 / About this part

What it is

Moose Offroad aluminium/steel rear sprocket 428 pitch 50T black/natural for selected Gas Gas, Husqvarna and KTM models. Check the fitment table for exact models and years.

This rear sprocket mounts to the hub and provides the final drive for your bike. It uses a hybrid design with a steel outer ring for durability and an aluminium inner for weight reduction. This is ideal for smaller displacement bikes where rotating mass matters but longevity is still required. Replace this when the teeth show signs of hooking or significant wear. Always fit a new chain when replacing sprockets to ensure even wear across the drivetrain. Use fresh sprocket bolts and follow OEM torque specs. This part is machined for a precise, model-specific fitment.

§ 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.
