§ 02 / About this part

What it is

The RENTHAL SPROCK R 428 47T SI UL SC, sprockets. Stocked by Iron Offroad, the UK MX hard parts specialist.

This component mounts directly to the rear hub to manage final drive delivery. Machined from 7075 T6 aluminium, it significantly reduces unsprung weight compared to steel alternatives. The integrated mud grooves are essential for UK winter tracks, clearing debris to prevent chain tension spikes and premature wear. Replace this part when teeth show signs of hooking or thinning. Use fresh mounting bolts and torque to OEM specifications to ensure a secure fitment. Changing tooth counts allows you to tune the bike for tight woods or fast MX circuits. It is a precision part for serious race builds.

Iron Offroad

Iron Offroad is the off-road sibling of Iron City and Iron stable — this is a UK shop for motocross, enduro, and trail-bike hard parts. All fitments live on the site, and listed against MX models KTM, Husqvarna, GasGas, Yamaha, Honda, Kawasaki, Suzuki, and Beta. Pick your bike on the timing-tower. Our USP is in the data, fully enriched to assist with accurate fitting and finding the right part for your bike quickly and easily. 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 & e-moto only. We operate from our huge storage facility in Leeds. Iron Offroad is a trading name of Iron Stable Ltd, registered in Mildenhall — Company No. 17061294. We have a RICH motorcycle history with multiple moto brands the images showing where we came from and our history, the business recently pivoted into hard parts and online retail.
