On a motorcycle stand there is mounted an electric motor, actuated by a pushbutton or switch, which motor, through a reducer unit, rotates a pinion; this latter meshes with a sector gear of the stand, whose center coincides with the hinging axis on which the stand is hinged on the motorcycle; actuation of the motor produces the sliding of the pinion on the sector gear and, accordingly, the rotation of the stand between the two conventional end positions called operative and rest position, respectively. |
