§ 02 / About this part
What it is
The MOTO-MASTER REAR SPROCKET 520 48T BL, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.
Machined from 7075-T6 aluminium, this component reduces unsprung weight at the hub. It uses a standard 520 pitch for MX and enduro bikes. You need a replacement when teeth begin to hook or show significant thinning. Adjusting the tooth count lets you tune your bike for specific track conditions or tighter trail sections. Always install a fresh chain when fitting new drive components to avoid rapid wear. Ensure you use new mounting bolts and torque them to OEM specifications. This part provides a direct fit to your hub for consistent power transfer.
