PROBLEM TO BE SOLVED: To prevent the increase in speed of a front wheel and the braking of a rear wheel on the turning inner side in a high-speed traveling by judging the traveling speed of a vehicle body from the shift position of a transmission provided on the vehicle body and the rotating speed of an engine. SOLUTION: When the steering operating angle judged on the basis of a signal from a steering sensor isθor more is judged (#209), the control of driving the step-up solenoid of a selector valve to in-operate the step-up clutch of a front wheel transmission and accelerating a front wheel is continued until the front wheel is restored to a value smaller than the set angleθ(#210-#214). When the engine is rotated at a high speed, a sub-inhibiting means is formed by the program for inhibiting the increase in speed of the front wheel and the braking of a side brake, and an inhibiting means is formed by the program for restraining and inhibiting the increase in speed of the front wheel and the braking of the side brake on the basis of the traveling speed judged from the shift stage of the transmission and the rotating speed of the engine.
