The invention provides a motorcycle inversed type front damper which comprises a sleeve. The upper end of the sleeve is fixed at an end cover. The lower end of the sleeve is arranged outside a fork pipe in a sleeving mode and is matched with the fork pipe in a sliding mode. The lower end of the fork pipe is connected into a bottom cylinder. A connecting rod is connected to the center of the end cover. The connecting rod penetrates through a guiding base from top to bottom and is connected with a piston body in a damper working cylinder. The lower end of the damper working cylinder is connected with the bottom cylinder. The lower end of the damper working cylinder is connected with the bottom cylinder through a whole type blocking head which is a three-section type step shaft with the diameters increased in sequence from top to bottom. The damper working cylinder is connected to the outer wall of a first section of shaft in a sleeving mode. The fork pipe is connected to the outer wall of a second section of shaft in a sleeving mode. The bottom cylinder is connected to the outer wall of a third section of shaft in a sleeving mode. An oil discharging hole is formed in the side wall of the damper working cylinder between the guiding base and the piston body. The coaxiality of the damper working cylinder and a fork pipe inner hole can be well guaranteed by connecting of the whole type blocking head so that a damper cannot generate abnormal sound, and meanwhile the fact that restored damping force is stabilized in the required fluctuation range can be guaranteed.
