The present invention relates to a four-wheel all-terrain motorcycle. The four-wheel motorcycle includes: a body coupled to a frame; an operating part disposed on a front side portion of the body, the operating part including handles on both sides thereof to steer wheels and control transmission of power; a sheet part coupled to a side of an upper portion of the body; a front wheel shaft disposed on a front of the body; front wheels including first and second wheels respectively coupled to both ends of the front wheel shaft; a first rear-wheel connecting body coupled to one side of the rear of the body; a second rear-wheel connecting body coupled to the other side of the rear of the body; rear wheels including a third wheel coupled to the first rear-wheel connecting body and a fourth wheel coupled to the second rear-wheel connecting body; a first motor coupled to a side of the third wheel to provide torqueto the third wheel; a second motor coupled to a side of the fourth wheel to provide torqueto the fourth wheel; and a controller electrically connected to the first and second motors to simultaneously or individually control the rotation speed of the first and second motors. According to the present invention, the controller may simultaneously or individually control the rotation speed of the first and second motors to allow stable driving on roads having rough road surfaces. Also, a curved path driving detection unit detects a rotation direction and angle, and the controller individually controls the rotation speed of the first and second motors according to the detected values so that an inner wheel has a rotation speed less than that of an outer wheel. Thus, when a vehicle is driven along a curved path, stability may be improved. Also, when an emergency stop is required, it may be easily executed by a user who is accustomed to driving an automobile because it is performed by applying a foot brake system generally found in automobiles. In addition, a foot brake and a hand brake may be operated at the same time to improve braking power.
