YAYE Honda CG125 CG150 CG200 Motorcycle Spare Parts A-Class Rear Wheel Hub with Aluminum Alloy and Polishing

The motorcycle rear hub is a crucial component that connects the rear wheel to the vehicle's transmission system. It is located at the center of the motorcycle's rear wheel and serves several key functions:

1. Wheel Mounting: The rear hub allows the rear wheel to be mounted on the motorcycle frame and supports the wheel hub and its spokes through bearings and axles.

2. Power Transmission: The rear hub carries gears or sprockets, enabling power to be transferred from the transmission system (such as a chain or belt drive) to drive the motorcycle forward.

3. Support for Braking Systems: Typically, the rear hub also supports the installation of brake discs or drums, which use friction to slow down or stop the rotation of the rear wheel.

4. Hub Protection and Sealing: The design of the rear hub aims to protect internal bearings and other critical components of the wheel hub while providing adequate sealing to prevent dust and moisture ingress.

5. Weight and Durability: Rear hubs are typically made from lightweight yet robust materials to reduce rotational inertia of the wheel and provide sufficient strength and durability for the operating conditions of the motorcycle.

In summary, the motorcycle rear hub is essential for supporting rear wheel operation, transmitting power, and facilitating braking systems, thereby influencing the performance and safety of the motorcycle.
