The utility model provides a damping work cylinder of a motorcycle shock absorber. The damping work cylinder comprises a circular tubular work cylinder body, a guide seat is arranged at one end of the work cylinder body, and the other end of the work cylinder body is connected with a bottom valve. A connecting rod penetrates through the guide seat, stretches into the work cylinder body, and is connected with a piston. A buffer spring is arranged between the guide seat and the piston, and shock absorber oil is injected into the work cylinder body. The damping work cylinder is characterized in that an oil drainage hole is formed in the position, between the guide seat and the piston, of the side wall of the work cylinder body. Due to the fact that the oil drainage hole is additionally formed in the cylinder body of the work cylinder of a damper, it is guaranteed that the oil of an outer oil cavity of the work cylinder of the damper can enter an inner high-pressure oil cavity smoothly and fast when the shock absorber works, and it is guaranteed that restoring damping force is stabilized within a required fluctuation range.
