§ 02 / About this part

What it is

The MOTO-MASTER SPROCKET STEEL REAR 420-48T SX65 TC65 2025, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This rear sprocket mounts to the rear hub and forms the final part of your drivetrain. It is a high-wear item that handles significant torque. Steel construction provides a longer service life than aluminium in muddy conditions. The 48T sizing is standard for many junior bikes. Watch for shark finning on the teeth as a sign it needs replacing. Always fit a new chain when swapping sprockets to ensure proper meshing. Use fresh sprocket bolts and thread lock for a secure install. This part is a direct OEM cross-reference.

§ 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.
