PURPOSE:To prevent any lengthening of an air intake duct and interference in intake air themselves and so on by forming each intake opening in the back of each cylinder, while setting up an upper side air cleaner in the space between left-right frame members and a lower side air cleaner at the side of an engine, respectively. CONSTITUTION:A V-bank A is suspended on a body frame 2 with a left-right pair of frame members 2a, 2b so as to be opened toward the front of a car body. In this case, each of vertical intake openings 9a, 9b for both upper and lower cylinders 10, 11 is formed inside and outside the V-bank A at the backside of these cylinders 10, 11. An upper side air cleaner 15 is installed in space between the paired frame members 2a, 2b at the upper part of a V-engine 8. On the other hand, a lower side air cleaner 18 is installed in space between these frame members 2a, 2b at the side of this V-engine 8. In addition, these air cleaners 15, 18 and intake openings 9a, 9b are connected with each other indirectly or directly at each of air ducts 17, 19 through each of carburetors 14, 14b. |
