§ 02 / About this part
What it is
The RENTHAL SPROCK R 520 46T SI UL SC, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.
This rear sprocket mounts directly to your rear hub to drive the final transmission. Machined from 7075-T6 aluminium, it significantly reduces unsprung weight compared to stock steel parts. This improves rear suspension tracking and acceleration. The ultralight design features mud-clearing grooves at the base of each tooth to prevent dirt buildup and reduce chain tension spikes. Replace your sprocket when teeth begin to hook or thin out. Running a worn sprocket will ruin a new chain in hours. Always install with new sprocket bolts and a medium-strength thread lock. Ensure chain tension is adjusted to your bike manufacturer specifications.
