Why does a motorcycle make an electronic clicking sound when starting?

[LaEdward]

When the electric start is activated, there is only a clicking sound and the starter motor and engine do not turn. There are basically the following reasons: 1. The battery is low on power and cannot drive the starter motor and engine to rotate. The battery power cannot be judged by the condition of the horn and lights to determine if it is low. 2. Starter motor failure, such as motor damage, worn carbon brushes, or dirty copper sleeves. The clicking sound is the sound of the starter relay engaging. With this sound, generally speaking, the electric starting circuit is basically normal. 3. The engine is stuck internally or has a stuck cylinder, but the possibility of this situation is extremely small, with the first two possibilities being more likely.
