An inner fender 16f that covers the front part of the rear wheel 15 from above is attached to the swing arm 16. A rear suspension 16s is interposed between the swing arm 16 and the rear part of the body frame 11. The rear suspension 16s is located in the center of the vehicle width and is disposed between the rear wheel 15 and the power unit 12 in a posture inclined downward and rearward.
[0016] The rear frame 20 includes a pair of left and right seat frames 41 extending rearward from the rear of the main frame 31, and a pair of left and right sub-frames 42 extending from the left and right pivot frames 32 to the seat frames 41. A front part of the crankcase 23 of the power unit 12 is fixed to the lower end part of the down frame 33 via a unit bracket 34, and a rear part of the crankcase 23 of the power unit 12 is fixed to the lower end part of the pivot frame 32 via a unit bracket 36. As a result, the power unit 12 is disposed behind the down frame 33, in front of the pivot frame 32, and below the main frame 31.
[0017] The power unit 12 is a single-cylinder engine (internal combustion engine) having a cylinder section 24 standing on the front upper part of a crankcase 23. Note that the power unit 12 is not limited to an internal combustion engine and may be an electric motor. When the power unit 12 is configured as an internal combustion engine, it is not limited to a single-cylinder engine and may be a multiple-cylinder engine.

The exhaust device 25 includes a first exhaust pipe 25a extending from the front surface of the cylinder portion 24 to below the power unit 12, a catalyzer 25b located downstream of the first exhaust pipe 25a, and a muffler 25c located downstream of the catalyzer 25b.
[0018] An intake passage 60 is connected to the rear surface of the cylinder portion 24. An air cleaner 61 is connected to the opposite end (corresponding to the upstream end) of the intake passage 60 from the cylinder portion 24. The air cleaner 61 is disposed below the seat 17, in a space surrounded by the rear frame 20. Note that the air cleaner 61 has a hollow box shape, and is therefore also referred to as an air cleaner 61 case or an air cleaner 61 box.
[0019] The saddle-ride type vehicle 10 includes a body cover 50 that covers each portion of the body frame 11. The body cover 50 includes a tank cover 51 that covers the fuel tank 29, a pair of left and right side covers 52 that cover the sides of the vehicle body, and a rear cover 53 that is located behind the side covers 52 and covers the lower part of the seat 17 from the outside in the left and right direction. The side covers 52 are located in the center between the front and rear of the vehicle body in a side view of the vehicle body, and therefore can also be called a center cover. In FIG. 1, the step support stay 30, the inner fender 16f, and the side cover 52 are indicated by two-dot chain lines.
[0020] The saddle-ride type vehicle 10 includes a front wheel brake device 71 that applies a braking force to the front wheel 13, and a rear wheel brake device 72 that applies a braking force to the rear wheel 15. Each of the brake devices 71, 72 is a hydraulic disc brake consisting of a brake disc and a caliper. It should be noted that a wide variety of known brake devices can be applied to each of the brake devices 71, 72.
[0021] In the saddle type vehicle 10, the ABS modulator 73 is disposed on one of the outer sides in the vehicle width direction (the right side in this configuration) shifted to the left or right from the vehicle width center LC (see FIG. 4). The ABS modulator 73 controls the braking force of two brake systems consisting of the front wheel brake device 71 and the rear wheel brake device 72. Although the configuration of the ABS modulator 73 is not particularly limited, the ABS modulator 73 of this configuration includes a pump that is driven by a motor to adjust the hydraulic pressure, a hydraulic circuit section connected to this pump, a valve that switches this hydraulic circuit section, an electronic control section that controls the motor, and the like, and functions as a braking force adjusting device that prevents the front wheels 13 and the rear wheels 15 from locking.
[0022] FIG. 2 is a view showing the ABS modulator 73 together with the surrounding structure from the right side of the vehicle body. In FIG. 2, the side cover 52 is removed, and the step support stay 30, the inner fender 16f, and the muffler 25 are indicated by two-dot chain lines. As shown in FIG. 2, the ABS modulator 73 is supported by the main frame 31 at a position rearward of the power unit 12 and forward of the rear suspension 16s, above the swing arm 16 and below the air cleaner 61. A brake hose 81 connected to a master cylinder 76 that generates hydraulic pressure in response to operation of a brake pedal 75, and a brake hose 82 connected to a rear wheel brake device 72 are connected to the upper surface of the ABS modulator 73. The brake hoses 81, 82 constitute a brake hose group for the rear wheel brakes.
[0023] A front wheel brake brake hose group 85 is also connected to the upper surface of the ABS modulator 73. The front wheel brake brake hose group 85 is made up of a brake hose 85a connected to a master cylinder for the front wheel brake provided on the handlebars 21, and a brake hose 85b connected to the front wheel brake device 71. The front wheel brake brake hose group 85 is routed along the right side surface of the front frame 19. The position and structure of the front wheel brake brake hose group 85 can be a widely applicable known configuration.
[0024] Next, the rear wheel brake brake hose group (hoses 81 to 83) and the related structure will be described. In this description, when the brake hoses 81, 82 are to be distinguished from each other, they will be referred to as a first brake hose 81 and a second brake hose 82, respectively. A brake pedal 75 that functions as an operator for the rear wheel brake is provided around the right-side step 28. The brake pedal 75 is located below the ABS modulator 73 and on the outer side of the swing arm 16 in the vehicle width direction, and is operated by the driver with his / her right foot. The master cylinder 76 is located rearward of the brake pedal 75 and below the ABS modulator 73, on the outer side (right side) of the swing arm 16 in the vehicle width direction, and generates hydraulic pressure in the first brake hose 81 in response to operation of the brake pedal 75.
[0025] A reservoir tank 77 for the rear wheel brake is disposed above the ABS modulator 73. The reservoir tank 77 is connected to the master cylinder 76 via a brake hose 83 (hereinafter, appropriately referred to as a third brake hose 83) and stores brake fluid. The third brake hose 83 extends downward from the master cylinder 76 behind the ABS modulator 73 and is connected to an upper portion of the master cylinder 76.
[0026] Fig. 3 is an enlarged view of the rear wheel brake brake hose group 81-83 in Fig. 2 together with the surrounding structure. Fig. 4 is a view showing the rear wheel brake brake hose group 81-83 together with the surrounding structure from the rear. In Fig. 4, for ease of understanding, the range of the ABS modulator 73 is shown by a dashed line. Also, the symbol LC in Fig. 4 indicates the vehicle width center. As shown in Fig. 3, the first brake hose 81 extends from an upper portion of the master cylinder 76, passing behind the ABS modulator 73, and toward the inside in the vehicle width direction. As shown in Fig. 4, the first brake hose 81 extends obliquely toward the inside and upward in the vehicle width direction so as to connect each connection point between the master cylinder 76 and the ABS modulator 73 in the shortest distance, and passes above the subframe 42. In addition, the first brake hose 81 passes through an area that overlaps with the ABS modulator 73 in a rear view of the vehicle body, or around that area.
[0027] In addition, the first brake hose 81 is passed forward of the third brake hose 83 and the second brake hose 82, that is, passed toward the ABS modulator 73, which is advantageous for shortening the first brake hose 81. By routing the first brake hose 81 in this manner, the first brake hose 81 does not protrude in the vehicle width direction beyond the ABS modulator 73, and the space required for routing the first brake hose 81 can be reduced.
[0028] As shown in FIG. 3, the second brake hose 82 extends rearward from the ABS modulator 73 and is connected to the rear wheel braking device 72. The second brake hose 82 in this configuration is arranged to have a rearward bent portion 82a that extends rearward and upward from the ABS modulator 73 and then bends convexly toward the rear of the vehicle body, a forward bent portion 82b that bends convexly toward the front of the vehicle body downstream of the rearward bend portion 82a, and a rearward extending portion 82c that extends rearward along the upper surface of the swing arm 16 downstream of the forward bend portion 82b. The rearward extending portion 82c is held by a plurality of downstream hose holding portions 91 provided on the swing arm 16 so as to extend linearly along the upper surface of the swing arm 16. Therefore, when the swing arm 16 swings up and down, the rearward extending portion 82c of the second brake hose 82 moves integrally with the swing arm 16.
[0029] In this configuration, a portion of the second brake hose 82 between the rear bent portion 82a and the front bent portion 82b is held by a single upstream hose holding portion 92 fixed to the subframe 42. The upstream hose holding portion 92 is provided at a height such that it horizontally overlaps with the ABS modulator 73, and holds the area between the rearward bent portion 82a and the frontward bent portion 82b in a downward-forward position relative to the body frame 11. This upstream hose holding portion 92 maintains the rearward bent portion 82a, and positions the uppermost portion of the rearward bent portion 82a above the ABS modulator 73. As a result, the hose portion of the rearward bent portion 82a is positioned rearward away from the ABS modulator 73, and sufficient space can be secured between the ABS modulator 73 and the second brake hose 82 for routing the first brake hose 81.
[0030] Furthermore, the upstream hose holding portion 92 holds the hose portion between the hose holding portion and the rearward extending portion 82c at the forward bent portion 82b that is bent convexly toward the front of the vehicle body. When the swing arm 16 swings up and down, the downstream portion moves up and down integrally with the swing arm 16 with respect to the inflection point of the forward bent portion 82b. This makes it possible to suppress bending and movement of the second brake hose 82 fixed to the body frame 11 and the swing arm 16. In other words, the forward bent portion 82b functions as a bending absorbing portion that suppresses bending and movement of the second brake hose 82.
[0031] In addition, the rear bent portion 82a and the front bent portion 82b form the second brake hose 82 in an S-shape in a side view of the vehicle body. This makes it easier to prevent the second brake hose 82 from protruding or moving in the vehicle width direction. In addition, the S-shape of the second brake hose 82 overlaps with the rear suspension 16s in a side view of the vehicle body, so it is not noticeable even if it is exposed to the outside.
[0032] 4, in a rear view of the vehicle body, the rear bent portion 82a and the front bent portion 82b are located below the air cleaner 61 and on the inside in the vehicle width direction relative to the outer position in the vehicle width direction of the ABS modulator 73. In a rear view of the vehicle body, the rear bent portion 82a and the front bent portion 82b extend in the vertical direction of the vehicle body in at least one of a region overlapping with the ABS modulator 73 and a periphery of that region. Therefore, the space required for arranging the rear bent portion 82a and the front bent portion 82b may be a narrow space in the vehicle width direction, and the rear bent portion 82a and the front bent portion 82b can be easily routed so as not to protrude in the vehicle width direction of the ABS modulator 73.
[0033] Furthermore, the first brake hose 81 extends in the vehicle width direction where it intersects with the second brake hose 82, forward of the rearward bent portion 82a and the forward bent portion 82b of the second brake hose 82 and rear of the ABS modulator 73. This makes it possible to minimize the area where the first brake hose 81 and the second brake hose 82 overlap. This makes it easier to prevent both hoses 82, 82 from protruding excessively in the vehicle width direction, compared to a case where the first brake hose 81 and the second brake hose 82 are arranged in parallel. Also, because parts of both hoses 82, 82 overlap in the fore-and-aft direction of the vehicle body, this also makes it easier to prevent both hoses 82, 82 from protruding excessively in the vehicle width direction.
[0034] As described above, the saddle-ride type vehicle 10 of this embodiment is equipped with a brake system in which the ABS modulator 73 is positioned offset to one side, left or right, from the vehicle width center LC, and has a first brake hose 81 connecting from the master cylinder 76 to the ABS modulator 73, and a second brake hose 82 connecting from the ABS modulator 73 to the rear wheel braking device 72 at the rear of the vehicle body, and as shown in FIG. 4, the first brake hose 81 and the second brake hose 82 cross each other when viewed from the rear of the vehicle body. According to this configuration, the overlapping area of the first brake hose 81 and the second brake hose 82 can be minimized, making it easier to prevent each hose 81, 82 from protruding in the vehicle width direction, etc. Therefore, even if the ABS modulator 73 is positioned offset to the left or right of the vehicle width center LC, it is easier to prevent each hose 81, 82 from protruding excessively in the vehicle width direction.
[0035] Note that, although the present embodiment illustrates a case in which the ABS modulator 73 does not overlap with the vehicle width center LC, even if a portion of the ABS modulator 73 overlaps with the vehicle width center LC, it is easy to suppress excessive protrusion of each of the hoses 81, 82 in the vehicle width direction. In other words, the "brake system in which the ABS modulator 73 is disposed shifted to one side, to the left or right, from the vehicle width center LC" of the present invention is not limited to cases in which the ABS modulator 73 does not overlap with the vehicle width center LC, but also includes cases in which a portion of the ABS modulator 73 overlaps with the vehicle width center LC.
[0036] 3, a portion of the second brake hose 82 extends rearward at a position higher than the upper surface of the ABS modulator 73, and extends below a portion of the second brake hose 82 in a direction in which the first brake hose 81 crosses the second brake hose 82. With this configuration, a sufficient space for the first brake hose 81 to pass can be secured below the second brake hose 82, and the second brake hose 82 and the first brake hose 81 can cross while being appropriately spaced apart.
[0037] As shown in FIG. 4, the first brake hose 81 and the second brake hose 82 cross each other on the inner side in the vehicle width direction than the outer side position of the ABS modulator 73 in the vehicle width direction, so that each hose 81, 82 can be routed without protruding outward in the vehicle width direction from the ABS modulator 73. In addition, when viewed from the rear of the vehicle body, the first brake hose 81 and the second brake hose 82 cross at least one of the area overlapping with the ABS modulator 73 and the area surrounding that area, so that the hoses 81, 82 can be routed by utilizing the space available behind the ABS modulator 73, etc.
[0038] In addition, since the second brake hose 82 is fixed to the body frame 11 via the upstream hose holding portion 92 at a height that horizontally overlaps with the ABS modulator 73, when the portion of the second brake hose 82 downstream of the fixing position on the body frame is fixed to the swing arm 16, the portion between the fixing position on the body frame and the downstream portion (corresponding to the forward bend portion 82b) is more likely to function as a flexure absorbing portion that suppresses flexure and movement of the portion of the second brake hose 82 between the body frame 11 and the swing arm 16.
[0039] In addition, the second brake hose 82 has a rearward bent portion 82a that bends convexly toward the rear of the vehicle body, and a forward bent portion 82b that bends convexly toward the front of the vehicle body downstream of the rearward bent portion 82a, and the portion between the rearward bent portion 82a and the forward bent portion 82b is fixed to the vehicle frame 11. According to this configuration, the rear bent portion 82a and the front bent portion 82b make the second brake hose 82 have an S-shape in a side view of the vehicle body, which makes it easier to suppress protrusion of the second brake hose 82 in the vehicle width direction. Moreover, the rear bent portion 82a makes it easier to ensure a space between the second brake hose 82 and the ABS modulator 73 through which the first brake hose 81 passes, and the front bent portion 82b makes it easier to suppress bending and movement of the portion of the second brake hose 82 between the vehicle frame 11 and the swing arm 16.
[0040] 4, the air cleaner 61 is provided above the second brake hose 82. With this configuration, the second brake hose 82 does not bend or move upward, so that the capacity of the air cleaner 61 can be increased and the shape of the air cleaner 61 can be changed without being affected by the second brake hose 82. Furthermore, the body frame 11 includes a seat frame 41 that supports the passenger seat 17, left and right pivot frames 32 located below the seat 17, and a subframe 42 that extends from the pivot frames 32 to the seat frame 41. As shown in Fig. 4, the first brake hose 81 passes above the subframe 42. With this configuration, the space above the subframe 42 can be effectively used as space for the first brake hose 81.
[0041] The above embodiment shows one aspect of the present invention, but the present invention is not limited to the above embodiment, and the configuration of the details may be appropriately changed. For example, although the ABS modulator 73 is disposed on the right side of the vehicle body in the embodiment, it may be disposed on the left side of the vehicle body. The ABS modulator 73 may be moved to an appropriate position within a range in which it is disposed on the outer side in the vehicle width direction. In addition, although the present invention has been described as being applied to the brake hose routing structure of a motorcycle shown in Fig. 1 and the like, the present invention is not limited thereto, and may be applied to the brake hose routing structure of any vehicle, such as a saddle-ride type vehicle. Note that vehicles to which the present invention can be applied are not limited to two-wheeled vehicles, and may be three-wheeled vehicles, four-wheeled vehicles, and the like. In addition, the power unit 12 is not limited to an internal combustion engine, and any drive source, such as an electric motor, may be applied.

With this configuration, the area where the first brake hose and the second brake hose overlap is kept to a minimum, making it easier to prevent each hose from protruding excessively in the vehicle width direction even when the ABS modulator is positioned on the side of the vehicle body.
[0044] (Configuration 2) A vehicle as described in configuration 1, wherein a portion of the second brake hose extends rearward at a position higher than the ABS modulator, and the first brake hose passes below the portion in a direction intersecting with the second brake hose.
