An ECU controls the damping force at the time of the expansion movement and contraction movement of the front fork. When detecting at least that the motorcycle is in a state of making a stop and the brake hydraulic sensor shows an output of more than or equal to a predetermined value, the ECU carries out a damping force reducing control for minimizing the damping force of the front fork. The ECU takes the following sequential steps of: sensing a start of an expansion movement of the front suspension after starting the damping force reducing control, sensing a termination of the expansion movement of the front suspension, and terminating the damping force reducing control.
