A motor tricycle that enables a cornering performance to be enhanced without the use of any differential gear and any active suspension is provided. The motor tricycle has a control unit for performing, when a travel speed V is not less than a predetermined speed V1, and a steering angle ¸ is not less than a predetermined angle ¸1, addition of an additional rotation speed ratio Rd1 meeting the thus travel speed V and the thus steering angle ¸ to an outer-wheel necessary rotation speed ratio R0 being a rotation speed ratio obtained in accordance with the handlebar steering angle ¸ detected by a steering angle detecting means on the assumption that no skid occurs between each of left and right rear wheels and a road surface at the time when a vehicle body turns a curve by the turning operation of a handlebar, specifically, a rotation speed ratio to an inner wheel, more specifically, a rotation speed ratio required for an outer wheel, and then permitting the outer wheel to be driven by drive means with a rotation speed ratio R resulting from the addition.
