To make a suspension sensor common in use in a plurality of kinds of vehicles.
The suspension sensor 26 is provided immediately below a steering shaft 28, i.e., on a lower surface of a central part in a vehicle width direction of a bottom bridge 20 for supporting a front fork 22. The suspension sensor 26 is a non-contact type sensor in a supersonic wave transmitting/receiving system or in a laser light transmitting/receiving system, and arranged so as to direct a supersonic wave or laser light to an upper surface of a front fender 25. A suspension stroke detection device 50 outputs an expansion/contraction amount of a front wheel suspension device by a time difference of the feed-out timing and the receiving (light receiving) timing of the supersonic wave or the laser light.
