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.
