[0009] According to the second aspect, the size of the middle cowl in the front-rear direction can be reduced, thereby making the middle cowl lighter.

[0010] A saddle-ride type vehicle according to a third aspect of the present invention is the saddle-ride type vehicle according to the first or second aspect, wherein the middle cowl (52) has a partition portion (71) that divides the cutout (61) into a front and rear portion.

[0011] According to the third aspect, the upper middle cowl and the lower middle cowl are connected by the partition portion, so that flapping of the upper middle cowl and the lower middle cowl can be suppressed, thereby improving the rigidity of the middle cowl.

[0012] A saddle-ride type vehicle according to a fourth aspect of the present invention is a saddle-ride type vehicle according to any one of the first to third aspects, wherein a front end portion (61f) of the cutout (61) may be located forward of a central axis (C) of the head pipe (11) in a side view of the vehicle.

[0013] According to the fourth aspect, the area of ​​the cutout can be enlarged compared to a configuration in which the front end of the cutout is located rearward of the central axis of the head pipe in a side view of the vehicle, which reduces the air resistance caused by the middle cowl when the vehicle is banked to the left or right, thereby improving handling stability.

[0014] A saddle-ride type vehicle according to a fifth aspect of the present invention is the saddle-ride type vehicle according to the third aspect, further comprising a radiator (40), and the partition portion (71) may cover a cap (43) of the radiator (40) from the outside in the vehicle width direction.

[0015] According to the fifth aspect, the radiator cap is hidden when viewed from the side of the vehicle, thereby improving the appearance of the saddle-ride type vehicle.

[0016] A saddle-ride type vehicle according to a sixth aspect of the present invention is a saddle-ride type vehicle according to the third or fifth aspect, wherein the middle cowl (52) has an outer middle cowl (60) located on the outer side in the vehicle width direction and an inner middle cowl (80) located on the inner side in the vehicle width direction, and the outer middle cowl (60) is formed with a first opening (62) located in front of the partition portion (71) and a second opening (63) located behind the partition portion (71), and the inner middle cowl (80) has a duct (81) at a position overlapping with the first opening (62) in a side view of the vehicle.

[0017] According to the sixth aspect, the traveling wind introduced into the duct can be directly released to the outside of the middle cowl through the first opening, so that a portion of the traveling wind guided to the inside of the middle cowl can be efficiently exhausted.

[0018] A saddle-ride type vehicle according to a seventh aspect of the present invention is the saddle-ride type vehicle according to the sixth aspect, wherein an imaginary straight line (L) passing through the rear end (67r) of the lower middle cowl (67) and the front end (61f) of the cutout (61) may intersect with 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 of the vehicle.

[0019] According to the seventh aspect, it is possible to prevent the wind discharged through the first opening and the second opening from hitting the upper body of the occupant. Effect of the Invention

[0046] As described above, the motorcycle 1 of this embodiment includes the middle cowl 52 having the upper middle cowl 65 provided above the notch 61 in a side view and the lower middle cowl 67 provided below the notch 61 in a side view. The rear end 65r of the upper middle cowl 65 is located rearward of the rear end 67r of the lower middle cowl 67 in a side view, and the upper middle cowl 65 covers at least a part of the cylinder head cover 35 from the outside in the vehicle width direction in a side view. According to this configuration, the upper middle cowl 65 covers the cylinder head cover 35, thereby suppressing deterioration of the appearance. Furthermore, since the rear end 67r of the lower middle cowl 67 is located forward of the rear end 65r of the upper middle cowl 65, the exhaust air of the radiator 40 is less likely to be obstructed by the lower middle cowl 67. Therefore, the heat exhaust effect of the radiator 40 can be improved while suppressing deterioration of the appearance.

[0047] A rear end portion 65r of the upper middle cowl 65 is located forward of a midpoint M of the axle of the front wheel 2 and the axle of the rear wheel 3. According to this configuration, the size of the middle cowl 52 in the front-to-rear direction can be reduced, thereby making the middle cowl 52 lighter in weight.

[0048] The middle cowl 52 has a partition portion 71 that divides the cutout 61 into a front portion and a rear portion. With this configuration, the upper middle cowl 65 and the lower middle cowl 67 are connected by the partition portion 71, so that flapping of the upper middle cowl 65 and the lower middle cowl 67 can be suppressed, thereby improving the rigidity of the middle cowl 52.

[0049] A front end 61f of the cutout 61 is located forward of the central axis C of the head pipe 11 in a side view. With this configuration, the area of ​​the cutout 61 can be increased compared to a configuration in which the front end of the cutout 61 is located rearward of the central axis C of the head pipe 11 in a side view. This reduces the air resistance caused by the middle cowl 52 when the vehicle is banked to the left or right, thereby improving handling stability.

[0050] Partition portion 71 covers cap 43 of radiator 40 from the outside in the vehicle width direction. With this configuration, cap 43 of radiator 40 is hidden in a side view, improving the appearance of motorcycle 1.

[0051] The middle cowl 52 has an outer middle cowl 60 located on the outer side in the vehicle width direction, and an inner middle cowl 80 located on the inner side in the vehicle width direction. The outer middle cowl 60 is formed with a first opening 62 located in front of the partition part 71, and a second opening 63 located behind the partition part 71. The inner middle cowl 80 has a duct 81 at a position overlapping with the first opening 62 in a side view. With this configuration, the traveling wind introduced into the duct 81 can be directly discharged to the outside of the middle cowl 52 through the first opening 62. Therefore, a portion of the traveling wind guided to the tire house inside the middle cowl 52 can be efficiently exhausted.

[0052] An imaginary straight line L passing through the rear end 67r of the lower middle cowl 67 and the front end 61f of the cutout 61 intersects with 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. According to this configuration, it is possible to make it difficult for the traveling wind exhausted through the first opening 62 and the second opening 63 to hit the upper body of the occupant.

[0053] The present invention is not limited to the above-described embodiment explained with reference to the drawings, and various modifications are possible within the technical scope of the present invention. For example, in the above embodiment, the inner middle cowl 80 is entirely covered by the outer middle cowl 60 in a side view, but the present invention is not limited to this configuration. That is, the inner middle cowl may be arranged on the exterior of the vehicle so as to be visible in a side view. In this case, the cutout of the middle cowl may be formed in the inner middle cowl, and the inner middle cowl may be included in at least one of the upper middle cowl and the lower middle cowl.

[0054] In the above embodiment, the upper middle cowl 65 covers only a portion of the cylinder head cover 35 in a side view, but the present invention is not limited to this configuration. The upper middle cowl may cover the entire cylinder head cover in a side view.

[0055] Furthermore, each outer middle cowl 60 may be formed of a single panel or a plurality of panels. For example, the outer middle cowl 60 may be formed such that the portion where the notch 61 is formed and the portion arranged so as to surround the portion where the notch 61 is formed are formed of separate panels.

[0056] In addition, the components in the above-described embodiments can be replaced with well-known components as appropriate without departing from the spirit of the present invention. [Explanation of symbols]
