§ 02 / About this part
What it is
The RENTHAL SPROCK R 520 49T OR UL SC, sprockets. Stocked by Iron Offroad, the UK MX hard parts specialist.
This aluminium drive component reduces unsprung weight at the hub. It sits on the rear wheel and transfers power to the ground. Replace it when the teeth start to hook or thin out. Always fit a new chain and front gear at the same time. This prevents old components from ruining your new part. These are CNC-machined for precise fitment to your specific hub. Mud grooves help clear debris from the chain contact point. Use thread lock on the bolts during installation. Check your chain tension after the first ride to ensure everything has seated. It is ideal for MX and enduro racing.

§ 05 / About Iron Offroad
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.
