The controller controls the shift spindle by a first step W1 of rotating the shift spindle in the first direction until a disengaging-side target angle Ta1 is reached; a second step W2 of returning the shift spindle in a second direction opposite to the first direction; and a third step W3 of rotating the shift spindle in the first direction up to the clutch-disengaging shift spindle angle ?1 and thereafter rotating the shift spindle in the second direction to return the shift spindle, upon detection of an output from a drum angle sensor, the output corresponding to shallow engagement of dog teeth.

Abstract: 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.
