The invention provides a damping working cylinder of a motorcycle shock absorber. The damping working cylinder comprises a working cylinder body, wherein a guide base is arranged at one end of the working cylinder body, the other end of the working cylinder body is connected with a bottom valve body, a connection rod penetrates through the guide base, extends into the working cylinder body and is connected with a piston body, a buffer spring is arranged between the guide base and the piston body, shock absorber oil is injected into the working cylinder body, and an oil discharge hole is formed in the portion, between the guide base and the piston body, of the side wall of the working cylinder body. Due to the fact that the oil discharge hole is additionally formed in the working cylinder body of the damping working cylinder, it is ensured that oil in an external oil cavity of the damping working cylinder can smoothly and rapidly enter an internal oil cavity when the shock absorber works, and the recovery damping force can be stabilized within the required fluctuation range as quick as possible.
