§ 02 / About this part

What it is

The RENTHAL SPROCK R 428 50T BL UL SC, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This rear sprocket sits on the hub to transfer power to the rear wheel. Machined from high-strength aluminium, it reduces unsprung weight on smaller displacement bikes, improving suspension response and acceleration. Mud grooves help clear debris from the chain rollers, which is vital for maintaining drive train efficiency in muddy conditions. Replace this part when the teeth show visible hooking or thinning. Always install with a new chain to prevent premature wear. Ensure your sprocket bolts are torqued to OEM specifications and secured with thread lock to prevent them backing out during a moto.

§ 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.
