Summary:PURPOSE: To improve charging efficiency, and increase engine output by forming an intake for running wind at the front outside surface of a frame, and providing a running wind intake opening formed at the inside surface at a space part around an engine. CONSTITUTION: Running wind which is guided by a fin 26 and flowed in tank rails 11 passing through an intake 25 flows rearward, and a part of it is guided by a fin 28 and blown off to a space part 35 between the tank rails 11 passing through a taking-out opening 27. The taking-out opening 27 is positioned behind a cylinder 20, and cold running wind flows sufficiently in the vicinity of a carburetor behind the cylinder 20 and an air cleaner 23, thus it is possible to suppress the atmospheric temperature of the carburetor and the air cleaner 23 so as to be low. As a result, heating of the carburetor can be prevented, and the temperature of the intake air of the carburetor becomes low, thus it is possible to improve the charging efficiency of the intake air, and increase engine output.
