[0002] The shock absorber is an important device of a motorcycle. The function of the motorcycle shock absorber is to mitigate and attenuate the impact and vibration of the motorcycle during driving, and to ensure the smoothness and comfort of driving, which is beneficial to improving the service life and handling stability of the motorcycle.
