PROBLEM TO BE SOLVED: To secure a sufficient bank angle by reducing a vehicle frontal projected area, and to efficiently arrange a pipe of a cooling device. SOLUTION: In a motorcycle where an engine unit 10 is mounted at a predetermined position of a vehicle body frame 101, a radiator 20 is disposed at an upper side in a front part of the engine unit 10, and an air-cooled oil cooler 30 is disposed at a lower side. The air-cooled oil cooler 30 is formed into a rough trapezoid of which the lower side is shorter than the upper side in a vehicle width direction viewed from a vehicle front face, and the radiator 20 is also formed into a rough trapezoid of which the lower side is shorter than the upper side in the vehicle width direction viewed from the vehicle front face. Besides, a radiator hose 26 on an outlet side of the radiator 20 is disposed on a side opposite to a side where oil hoses 35, 36 of the oil cooler 30 are disposed. Thereby, the vehicle frontal projected area can be reduced to secure the sufficient bank angle, and to efficiently arrange the pipe of the cooling device. COPYRIGHT: (C)2010,JPO&INPIT |
