PROBLEM TO BE SOLVED: To provide a motorcycle capable of constituting a front wheel suspension portion pivoting a front wheel so as to be inclined freely, with a simple structure. SOLUTION: In this motorcycle provided with a buffer 55 having an outer tube 51 at the front wheel suspension portion 41 pivoting the front wheel 43 and an inner tube 53 engaged with the outer tube 51 so as to be relatively oscillated freely in a vertical direction, a steering portion 71 which applies steering angle to the front wheel suspension portion is fixed at a tube 53 on the upper side among the respective tubes, the steering portion 71 is supported at a vehicle body frame 3 through an upper side joint portion 67 so as to be inclined freely by interlocking with the action of the buffer 55 so as to integrally steer the steering portion 71 and the front wheel suspension portion 41, and one edge portion 47a of a swing arm 47 is jointed to the tube 51 on the lower side through a lower side joint portion 38 arranged on a steering shaft including the upper side joint portion 67, thus oscillating the other edge portion 47b of the swing arm 47 at a vehicle body frame 3 so as to be oscillated freely.
