How to use: First, make sure your kart has a 40mm axle. Then, install the Rocket Sprocket Mini Sprocket Hub onto the axle carefully. You'll need to align the 8mm wide keyway slot properly. Attention: Avoid using it on axles with non - 40mm sizes, as it may not fit well and could cause safety issues. Maintenance advice: Regularly check the tightness of the sprocket hub. Clean it with a soft cloth to remove dirt and debris. If you notice any signs of wear, replace it promptly to keep your kart running smoothly.
