§ 02 / About this part
What it is
The RENTHAL SPROCKET R 520 50T OR SC TWIN, sprockets. Stocked by Iron Offroad, the UK MX hard parts specialist.
Constructed with a lightweight aluminium centre and a durable steel outer ring, this sprocket mounts to your rear hub. It is designed to withstand the high torque of modern four-strokes while keeping rotating mass to a minimum. Replace this unit if the teeth show signs of hooking or if you are installing a new chain. The 50-tooth size is a versatile choice for most MX and enduro applications, providing a reliable balance of acceleration and speed. Ensure the hub surface is clean before installation and always use fresh locking fasteners.

§ 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.
