§ 02 / About this part
What it is
The MOTO-MASTER REAR SPROCKET 520 50T BL, 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. 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 where weight matters.
