Convection cooled radiator for an all terrain vehicle

摘要

A straddle-type vehicle includes a frame supporting front and rear wheels, a seat supported above the frame, an engine supported by the frame below the seat to supply power to at least one of the front and rear wheels, and a coolant system having a radiator mounted to the frame and communicated with the engine to cool coolant circulating through coolant passages provided in the engine. The radiator is mounted to the frame such that the radiator is disposed at an angle with respect to a vertical axis of the frame such that an upper end of the radiator is located closer to a front portion of the vehicle than a lower end of the radiator.
