PROBLEM TO BE SOLVED: To prevent a motorcycle for executing anti-lock brake control of a front wheel brake independently of a rear wheel brake from largely changing behavior during the independent anti-lock brake control of the front wheel brake and from being affected by a feel of the failure of a brake fluid pressure for improving braking feeling. SOLUTION: When anti-lock brake control is executed by using the front wheel brake only in the state that the friction coefficient of a road surface is a predetermined value or more, a counter is set, as the slippage rate of a front wheel being less than a predetermined value gets to the predetermined value or more, for counting in such a manner that the lapse of time from the slippage rate being the predetermined value or more in the state of setting the counter can be reset each time the slippage rate is the predetermined value or more. The brake fluid pressure of the front wheel brake is prohibited from being increased and held in such a state before the lapse of time reaches a predetermined time.
