Abstract: A multifunctional motorcycle rearview mirror structure includes a rearview mirror and a journey data recorder. The rearview mirror is mounted to a motorcycle and has a major surface that forms a mirror surface in which a display is mounted and an opposite major surface in which a coupling trough including two first electrical conduction sections is formed and includes a control module and a GPS signal transmitter/receiver unit mounted therein. The journey data recorder is removably coupled to the coupling trough of the rearview mirror and includes two second electrical conduction sections respectively corresponding to the first electrical conduction sections. As such, the journey data recorder is coupled to the coupling trough of the rearview mirror with electrical engagement established between the first and second electrical conduction sections. The GPS signal transmitter/receiver unit receives a GPS signal to achieve GPS navigation that is displayable on the display.
