PURPOSE:To improve cooling efficiency and obtain stable engine output by disposing a radiator at an opening provided at the front face of a fairing located above the engine and communicating a space formed between the engine and a tank above with the rear face of the radiator. CONSTITUTION:A specific space S is formed between an engine 8 and a tank 6 above, and this space S is communicated with the rear face of an upper radiator 12 disposed at the opening provided at the front face part of a fairing 14 located above the engine 8. Hot air apt to be filled in the upper part of the engine 8 is discharged backward from a rear exhaust pipe 8c utilizing exhaust wind after cooling an upper radiator 12. As a result, the ventilation of the upper radiator 12 becomes favorable, and thus cooling efficiency is improved. In addition, the tank 6 located above and a carburetor 11 are not affected by the heat in the space S at the time of running, and thereby stable engine output can be obtained. |
