§ 02 / About this part

What it is

The MOTO-MASTER SPROCKET STEEL REAR 420-50T SX65 TC65 2025, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This rear sprocket mounts to the hub and drives the rear wheel. It is subjected to constant stress and grit. The 50T sizing provides maximum acceleration for tight tracks and technical sections. Steel construction offers superior durability over aluminium alternatives. Look for hooked teeth or side wear as indicators for replacement. Always use new sprocket bolts and a fresh chain for the best results. This part is a direct replacement for the OEM unit. It is essential for maintaining drive efficiency on your 65cc bike.

§ 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.
