§ 02 / About this part
What it is
The MOTO-MASTER REAR SPROCKET 520 52T BL, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.
This component mounts directly to your rear hub to drive the final transmission. Machined from 7075-T6 aluminium, it significantly reduces unsprung weight and rotating mass compared to steel alternatives. This improves rear suspension tracking and throttle response on your bike. Replace your sprocket once the teeth show signs of hooking or thinning. Gritty UK track conditions accelerate wear, making regular inspection vital for your drivetrain. Always fit new sprocket bolts and use a medium-strength thread locker during installation. Ensure the hub mounting surface is clean to prevent run-out and premature chain wear.
