SPKF052 Description Lextek Front Sprocket 428-15T 156FMI 157FMI

The front sprocket, also known as the countershaft sprocket, is a key component in a motorcycle's drivetrain. Located at the output shaft of the engine or transmission, it engages with the motorcycle's chain to transmit power from the engine to the rear wheel. The front sprocket works in conjunction with the rear sprocket and chain to control the motorcycle’s gearing, affecting acceleration, top speed, and overall performance. Its size and number of teeth influence the bike’s torque and speed characteristics.

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.
