Summary:PROBLEM TO BE SOLVED: To reduce intake sound by differentiating shapes of a plurality of intake ducts and introducing a flowing wind from an intake air introduction port. to an air cleaner via these intake ducts. SOLUTION: An intake system which is provided with an air cleaner 24 is constituted in such a state as introducing a flowing wind from an intake air introduction port 50a, which takes the flowing wind of an air introduction part 50 therein, to the air cleaner 24 via a pair of left/right intake ducts 51, 52. The pair of left/right intake ducts are formed into different shapes so as to be asymmetric in its left and right. Namely, a right side surge tank 51a has a cap of a radiator 29 arranged therein so that the left-side surge tank 52a is formed comparatively small. This constitution can change a natural frequency despite of a simple structure, effectively eliminate resonance sound, and reduce the intake sound.
