According to this structure, the upper intermediate cowling 65 covers the cylinder head cover 35, whereby deterioration of the external appearance can be suppressed. Further, since the rear end 67r of the lower intermediate cowling 67 is positioned forward with respect to the rear end 65r of the upper intermediate cowling 65, the exhaust of the radiator 40 is difficult to be blocked by the lower intermediate cowling 67. Therefore, the heat release effect of the radiator 40 can be improved while suppressing the deterioration of the external appearance.
The rear end portion 65r of the upper intermediate cowling 65 is located forward of the midpoint M between the axles of the front wheels 2 and the rear wheels 3. According to this structure, the intermediate cowling 52 can be reduced in size in the front-rear direction, and the intermediate cowling 52 can be reduced in weight.
The intermediate cowling 52 has a partition 71 that divides the slit 61 forward and backward. According to this structure, the upper intermediate cowling 65 and the lower intermediate cowling 67 are connected by the partition 71, so that the respective rattling of the upper intermediate cowling 65 and the lower intermediate cowling 67 can be suppressed, and the rigidity of the intermediate cowling 52 can be improved.
The front end portion 61f of the notch 61 is located forward of the central axis C of the head pipe 11 in side view. According to this configuration, the area of the notch 61 can be enlarged as compared with a configuration in which the tip of the notch 61 is located rearward of the central axis C of the head pipe 11 in side view. This reduces the air resistance caused by the intermediate cowling 52 when the vehicle is tilted to the left and right, and improves the steering stability.
The partition 71 covers the cover 43 of the radiator 40 from the outside in the vehicle width direction. According to this structure, the cover 43 of the radiator 40 is hidden in a side view, so that the exterior appearance of the motorcycle 1 is improved.
The intermediate cowling 52 includes an outer intermediate cowling 60 positioned on the outer side in the vehicle width direction and an inner intermediate cowling 80 positioned on the inner side in the vehicle width direction. The outer intermediate fairing 60 has a first opening 62 located in front of the partition 71 and a second opening 63 located behind the partition 71. The inner intermediate cowling 80 has a passage 81 at a position overlapping the first opening 62 in side view. According to this structure, the traveling wind introduced into the duct 81 can be directly escaped to the outside of the intermediate cowling 52 through the first opening 62. Therefore, a part of the traveling wind of the tire cover guided to the inner side of the intermediate fairing 52 can be efficiently discharged.
An imaginary straight line L passing through the rear end 67r of the lower intermediate fairing 67 and the front end 61f of the cutout 61 intersects an imaginary line segment S connecting the axle of the front wheel 2 and the axle of the rear wheel 3 in a side view. With this structure, the traveling wind discharged through the first opening 62 and the second opening 63 can be made difficult to contact the upper body of the occupant.
The present invention is not limited to the embodiment described above with reference to the drawings, and various modifications are considered within the technical scope thereof.
For example, in the above embodiment, the entire inner intermediate cowling 80 is covered with the outer intermediate cowling 60 in a side view, but the structure is not limited thereto. That is, the inner intermediate cowling can be visually disposed in a side view in the vehicle exterior. In this case, the notch of the intermediate cowling may be formed in the inner intermediate cowling, and at least one of the upper intermediate cowling and the lower intermediate cowling may include the inner intermediate cowling.
In the above embodiment, the upper intermediate cowling 65 covers only a part of the cylinder head cover 35 in a side view, but is not limited to this configuration. The upper intermediate cowling may also cover the entirety of the cylinder head cover in side view.
Each of the outer intermediate cowls 60 may be formed of a single plate or a plurality of plates. For example, the outer intermediate fairing 60 may be formed by a separate plate with a portion where the cutout 61 is formed and a portion arranged so as to surround the portion where the cutout 61 is formed.
The components in the above-described embodiments may be replaced with known components as appropriate within a range not departing from the gist of the present invention.
