SPKR181"In the category of Sprockets, Rear Sprockets"
The rear sprocket on a motorcycle is a key component of the drivetrain system, located on the rear wheel hub. It works in conjunction with the front sprocket and the chain to transmit power from the engine to the rear wheel, propelling the motorcycle forward. The rear sprocket features a series of teeth that mesh with the chain, and its size affects the motorcycle’s gearing and performance characteristics. A larger rear sprocket increases torque and acceleration, while a smaller one improves top speed and fuel efficiency. Proper maintenance and alignment of the rear sprocket are essential for optimal drivetrain performance and safety.
