Abstract
A water-cooled engine mounted on a vehicle wherein a mass concentration keeps the center of mass at a low position. In a saddle-ride type four-wheel vehicle, a radiator and a fuel tank are supported on lower frames, and are arranged, side by side, so as to be distributed respectively on the right-hand side and on the left-hand side so as to overlap each other when viewed from a side. In addition, the fuel tank and the radiator are disposed at the rear of a front suspension arm and at the rear of an engine. As a result, the concentration of mass and the keeping of the mass at a lower position are achieved. Moreover, the fuel tank and the radiator are allowed to stretch outwards beyond the upper frames. Consequently, the fuel tank can have a larger capacity and a ventilation path that leads to the radiator can be secured.
