[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the description, directions such as front, rear, left, right, up and down are the same as directions relative to the vehicle body unless otherwise specified. In addition, the symbol FR in each drawing indicates the front of the vehicle body, the symbol UP indicates the upper side of the vehicle body, and the symbol LH indicates the left side of the vehicle body.

[0009] [Embodiment Mode] FIG. 1 is a side view of a saddle-ride type vehicle 10 according to an embodiment of the present invention. The saddle-type vehicle 10 is a vehicle that includes a body frame 11, a power unit 12 supported by the body frame 11, a front fork 14 that supports a front wheel 13 so as to be steerable, a swing arm 16 that supports a rear wheel 15, and a seat 17 for a passenger. The saddle-ride type vehicle 10 is a vehicle in which a rider sits astride a seat 17. The seat 17 is provided above the rear part of the body frame 11.

[0010] The body frame 11 includes a head pipe 18 provided at the front end of the body frame 11, a front frame 19 located rearward of the head pipe 18, and a rear frame 20 located rearward of the front frame 19. The front end of the front frame 19 is connected to the head pipe 18. The seat 17 is supported by a rear frame 20 .

[0011] The front fork 14 is supported by a head pipe 18 so as to be steerable left and right. The front wheel 13 is supported by an axle 13a provided at the lower end of the front fork 14. A steering handle 21 that is held by a rider is attached to the upper end of the front fork 14.

[0012] The swing arm 16 is supported by a pivot shaft 22 that is supported by the body frame 11. The pivot shaft 22 is a shaft that extends horizontally in the vehicle width direction. The pivot shaft 22 is inserted into the front end of the swing arm 16. The swing arm 16 swings up and down about the pivot shaft 22. The rear wheel 15 is supported by an axle 15 a provided at the rear end of a swing arm 16 .

[0013] The power unit 12 is disposed between the front wheels 13 and the rear wheels 15 and is supported by the body frame 11. The power unit 12 is an internal combustion engine. The power unit 12 includes a crankcase 23 and a cylinder portion 24 that houses a reciprocating piston. An exhaust device 25 is connected to an exhaust port of the cylinder portion 24. The output of the power unit 12 is transmitted to the rear wheels 15 by a driving force transmission member that connects the power unit 12 and the rear wheels 15 .

[0014] The saddle-ride type vehicle 10 also includes a front fender 26 that covers the front wheel 13 from above, a rear fender 27 that covers the rear wheel 15 from above, a step 28 on which a rider places his or her feet, and a fuel tank 29 that stores fuel used by the power unit 12. The front fender 26 is attached to the front fork 14. The rear fender 27 and the step 28 are provided below the seat 17. The fuel tank 29 is supported by the body frame 11.

[0015] The saddle-ride type vehicle 10 includes a vehicle body cover 30 that covers the vehicle body. The vehicle body cover 30 includes a front cover 31 that covers the front part of the vehicle body from the front and the left and right sides, and an inner cover 33 that covers the front frame 19 from above. The upper surface of the inner cover 33 is formed in a shape having a foot straddle portion 33M that is recessed downward between the head pipe 18 and the seat 17.

[0016] FIG. 2 is a diagram showing a part of the saddle-ride type vehicle 10 with the body cover 30 removed. The passenger seat 17 can accommodate two passengers, a driver and a passenger, and is also called a tandem seat. The driver's step 28 is disposed below the front frame 19 at positions corresponding to the left and right sides of the crankcase 23. The passenger's step 38 is disposed behind the rear frame 20 and the crankcase 23. Both steps 28 and 38 are steps for the passenger. The passenger's step 38 is also called a pillion step and a tandem step, and will be referred to as a pillion step 38 below.

[0017] The pillion step 38 is supported by the left and right swing arms 16 via stays 38S, and is disposed at a position overlapping with the rear wheel 15 in a side view of the vehicle body. An exhaust muffler 25M (see FIG. 1), which constitutes a part of the exhaust device 25, is disposed below one of the left and right pillion steps 38 (the right side in this embodiment). The exhaust muffler 25M is covered from above with a muffler cover 25C (see FIG. 1). A drive chain 12CN (see FIG. 2) is used as a driving force transmission member connecting the power unit 12 and the rear wheel 15, but a member other than the drive chain 12CN may be used.

[0018] 2, the front frame 19 extends rearward and downward from the head pipe 18 along the center of the vehicle width, below the seat 17, and to the vicinity of the rear wheel 15. The front frame 19 is also referred to as a main frame and a center frame. A pair of left and right pivot plates 34 are joined to the rear of the front frame 19, and the pivot shaft 22 is supported by the pivot plates 34.

[0019] A pair of left and right sub-frames 20S extending rearward and upward from a lower front position of the seat 17 are connected to the front frame 19. The sub-frames 20S extend rearward and upward with a gap between them on the left and right, and function as a seat frame or the like that supports the seat 17. The rear frame 20 extends rearward and upward from the rear of the front frame 19, and is joined to the sub-frames 20S. The sub-frames 20S and the rear frame 20 form the rear portion of the body frame 11. The weight of an occupant or the like acting from the seat 17 is also supported by the rear frame 20, so the rear frame 20 also functions as a part of the seat frame. A rear suspension 35 is interposed between the rear frame 20 and the rear wheel 15.

[0020] The power unit 12 is supported in front of the pivot plate 34 and below the front frame 19. The power unit 12 has an engine in which a cylinder portion 24 protrudes horizontally forward from a crankcase 23. The crankcase 23 has an upwardly bulging shape to accommodate a plurality of shaft members and gear mechanisms, and is the vertically large part of the power unit 12. Therefore, the vertical gap between the crankcase 23 and the front frame 19 is relatively narrower than the vertical gap between the cylinder portion 24 and the front frame 19.

[0021] As shown in Fig. 2, a throttle body 36, which constitutes part of the intake system, is disposed in the vertical gap between the cylinder portion 24 and the front frame 19. The throttle body 36 is provided in an intake path that connects the cylinder portion 24 to an air cleaner 37 disposed under the seat 17. The throttle body 36 has a function of adjusting the amount of intake air to the cylinder portion 24 in response to the operation of a throttle operator 21R (see Fig. 1) provided on the handlebars 21. To achieve this function, a throttle wire 41 (see Figs. 1 and 2) extending from the throttle operator 21R is connected to the throttle body 36.

[0022] FIG. 3 is a diagram showing the handle 21 together with the surrounding configuration. As shown in Fig. 3, the throttle operator 21R is provided on the right side of the handlebar 21 and is operated by the rider's right hand. Two throttle wires 41 extend from the throttle operator 21R. These throttle wires 41 pass in front of the head pipe 18 and extend to the left side of the head pipe 18, then extend rearward along the left side of the front frame 19, and then extend downward across the front frame 19 from above in the left-right direction to connect to the throttle body 36.

[0023] As shown in Figures 2 and 3, a harness 44 bundling a plurality of wires extends in the front-rear direction along the right side surface of the head pipe 18 and the front frame 19. Wires branch out from different points of the harness 44 and are connected to electrical components in various parts of the vehicle body. The harness 44 is also called a main harness or a wire harness. Note that Figure 2 omits some of the wiring and piping. As shown in FIG. 3, a headlight 51 and a meter unit 52 are provided in front of the head pipe 18.

[0024] 1, the saddle-ride type vehicle 10 includes a front brake device 61 that applies a braking force to the front wheel 13, and a rear brake device 62 that applies a braking force to the rear wheel 15. The front brake device 61 and the rear brake device 62 may be either a hydraulic disc brake consisting of a brake disc and a caliper, or a drum brake, or any known brake device may be appropriately applied.

[0025] The saddle-ride type vehicle 10 is provided with a front brake lever 63 (see FIG. 1) on the right side of the handlebar 21. The front brake lever 63 is located in front of the throttle operator 21R and is operated by the rider's right hand. Operation of the front brake lever 63 is transmitted to the front brake device 61 via a front brake cable 71 (hereinafter referred to as the first brake cable 71).

[0026] As shown in FIG. 3, the first brake cable 71 extends from the front brake lever 63 side, passes in front of the head pipe 18 , to the left side of the head pipe 18 , and then extends downward to connect to the front braking device 61 . That is, the connection destination of the first brake cable 71 in the front braking device 61 is located on the left side, which is the left-right opposite side of the front brake lever 63. In other words, the front braking device 61 is disposed on the left-right opposite side of the front brake lever 63. Therefore, the first brake cable 71 straddles the front of the head pipe 18 from left to right, so that it can be routed to the front braking device 61 side.

[0027] If the front brake device 61 is hydraulic, the first brake cable 71 is a hydraulic pipe, and if it is not hydraulic (i.e., if it is mechanical), the first brake cable 71 is a wire cable. Since the inner cable of the wire cable is pulled by the brake operation, the wire cable tends to move more easily in response to the brake operation than the hydraulic pipe.

[0028] Incidentally, the saddle-ride type vehicle 10 is an automatic clutch type vehicle in which the switching between power transmission / cut-off between the power unit 12 and the rear wheels 15, which are the driving wheels, is performed by a centrifugal clutch or the like. Therefore, a clutch operator for manually operating the clutch by the rider is not required, and for example, a clutch lever is not required on the handlebars 21.

[0029] Here, FIG. 4 shows the left side portion of the handle 21 together with the surrounding structure. As shown in FIG. 4, the saddle-ride type vehicle 10 of this configuration is provided with a rear brake lever 64 on the left side of the handlebar 21. The rear brake lever 64 is located in front of the left grip portion 21L that the rider holds with his / her left hand, and can be operated with the rider's left hand. Operation of the rear brake lever 64 is transmitted to the rear brake device 62 via a rear brake cable 72 (hereinafter referred to as the second brake cable 72). The rear brake lever 64 functions as a rear brake operator. However, the rear brake operator of the present invention is not limited to a lever shape, and any operator can be applied.

[0030] More specifically, the upstream end of the second brake cable 72 is connected to a CBS (Combined Brake System) module 65 provided around the base end of the rear brake lever 64 . The CBS module 65 is a mechanism that realizes linked braking of the front and rear wheels by distributing the operating force of the rear brake lever 64 to the rear braking device 62 and the front braking device 61, respectively. However, the CBS module 65 is not essential, and the upstream end of the second brake cable 72 may be directly connected to the rear brake lever 64 without providing the CBS module 65.

[0031] A switch box 66 equipped with various switches is provided at the base end of the left grip portion 21L. A wiring 44A branched off from the harness 44 is connected to the switch box 66. This wiring 44A passes in front of the head pipe 18 and extends from left to right to be connected to the harness 44 arranged on the right side of the head pipe 18.

[0032] FIG. 5 is a diagram showing the front frame 19 together with the surrounding configuration from the upper right. The routing structure of the second brake cable 72 will be described with reference to Figs. 3 and 5 etc. As shown in FIG. 3, the second brake cable 72 extends downward from the CBS module 65 toward the left side of the head pipe 18, and then extends from the left side of the head pipe 18 downward and rearward along the left side surface of the front frame 19.

[0033] A first cable holding member 81 that holds the second brake cable 72 is provided on the left side surface of the front frame 19. The first cable holding member 81 holds the second brake cable 72 so as to maintain a state in which the second brake cable 72 extends from the left side of the head pipe 18 along the left side surface of the front frame 19. Furthermore, the first cable holding member 81 holds the second brake cable 72 at a position spaced to the left of the front frame 19. Therefore, on the left side of the front frame 19, the second brake cable 72 is held in a state spaced to the left from the head pipe 18 and the front frame 19. Therefore, even if the second brake cable 72 attempts to move in response to a braking operation, the second brake cable 72 does not come into contact with the head pipe 18 and the front frame 19.

[0034] Of the second brake cable 72, the portion from the rear brake lever 64 to the vicinity of the first cable holding member 81 corresponds to the "upstream portion 72A of the second brake cable 72." As described above, the upstream portion 72A of the second brake cable 72 is located on the rear brake lever 64 side (the left side in this embodiment) with respect to the vehicle width center.

[0035] 2 and 5 is a portion downstream of the first cable holding member 81. As shown in Figures 2 and 5, the second brake cable 72 passes from the location of the first cable holding member 81 below the front frame 19 and is routed to the right side of the front frame 19. Of the second brake cable 72, the portion that straddles the front frame 19 from below is indicated by the reference symbol 72B, and will be referred to as "straddle portion 72B of the second brake cable 72".

[0036] The second brake cable 72 crosses the front frame 19 from below from the left side to the right side at a position forward of the crankcase 23 and above the cylinder portion 24. The straddling portion 72B of the second brake cable 72 is a wide vertical space among the vertical spaces between the power unit 12 and the front frame 19, that is, the space between the cylinder portion 24 and the front frame 19. This makes it easy to arrange the second brake cable 72, and also allows the second brake cable 72 to be arranged away from the crankcase 23 and the cylinder portion 24, which are heat sources. This makes it easier to avoid the thermal effects on the second brake cable 72.

[0037] 2 and 5, intake system components including the throttle body 36 are disposed in front of the crankcase 23 and above the cylinder section 24, and below the front frame 19. The straddling portion 72B of the second brake cable 72 passes through a space that is open above and below the intake system components including the throttle body 36 and the front frame 19, thereby providing the intake system components between it and the power unit 12. This makes it easier to avoid the thermal effects of the power unit 12 on the second brake cable 72 by the intake system components.

[0038] The second brake cable 72 straddles the front frame 19 from below, and then extends rearward and downward along the right side surface of the front frame 19. A second cable holding member 82 that protrudes to the right is provided at the rear of the front frame 19, and this second cable holding member 82 holds the second brake cable 72. The second cable holding member 82 holds the second brake cable 72 so that the second brake cable 72 is along the right side of the front frame 19 and is spaced away from the right side of the front frame 19, preventing the second brake cable 72 from coming into contact with the crankcase 23 of the power unit 12, etc.

[0039] Of the second brake cable 72, the portion downstream of the straddling portion 72B corresponds to "the downstream portion 72C of the second brake cable 72". A second cable holding member 82 that holds the downstream portion 72C to the front frame 19 is located rearward of the power unit 12 and, as shown in FIG. 2, on the front-to-rear width of the pivot shaft 22 in a side view of the vehicle body.

[0040] The swing arm 16, which supports the rear brake device 62 and the rear wheel 15, rotates (swings) up and down with the pivot shaft 22 as a reference, so by holding the second brake cable 72 on the fore-and-aft width of the pivot shaft 22, the rotation reference position of the swing arm 16 and the rotation reference position of the second brake cable 72 become close to each other. Therefore, with the second cable holding member 82 as a reference, the second brake cable 72 can be moved up and down in accordance with the up and down movement of the swing arm 16 without being significantly bent, which is advantageous for shortening the second brake cable 72.

[0041] In this way, by holding the second brake cable 72 on the fore-and-aft width of the pivot shaft 22, the second brake cable 72 can be made to move easily up and down in accordance with the up and down movement of the second brake cable 72 without significantly bending the second brake cable 72.

[0042] The second brake cable 72 downstream of the second cable holding member 82 enters between the left and right swing arms 16, passes below the right swing arm 16 and on the inside in the vehicle width direction, extends rearward, and is connected to the rear brake device 62, as shown in FIG.

[0043] Third cable holding members 83 (see FIG. 2) are provided on the right swing arm 16 with a gap between them in the front and rear, and the second brake cable 72 is held by these third cable holding members 83. This holds the second brake cable 72 between the right swing arm 16 and the rear wheel 15 in the vehicle width direction and below the right swing arm 16 in the vehicle body up-down direction along the right swing arm 16. This makes it easier to maintain the second brake cable 72 in a straight line shape, lengthens the straight portion of the rear brake cable 72, and makes it easier for rainwater adhering to the rear brake cable 72 to be discharged along the rear brake cable 72 and out of the rear brake cable 72, making it easier to drain water.

[0044] The connection destination of the second brake cable 72 of the rear braking device 62 is located below the rear part of the right swing arm 16 and to the right of the rear wheel 15. In other words, it can be said that the rear braking device 62 is located on the left-right opposite side of the rear brake lever 64 and at a position corresponding to the rear of the vehicle body. In this configuration, the rear brake device 62 is disposed on the left-right opposite side of the rear brake lever 64 and at a position corresponding to the rear of the vehicle body, so the second brake cable 72 needs to straddle some part of the body frame 11 from left to right.

[0045] 1, the rear brake cable 72 passes inside the exhaust muffler 25M in the vehicle width direction and overlaps with the exhaust muffler 25M in the vehicle width direction. This makes the rear brake cable 72 less visible due to the exhaust muffler 25M, which is advantageous for improving the appearance of the saddle-ride type vehicle 10. In addition, the exhaust muffler 25M can function as a protective member that protects the rear brake cable 72 from surrounding flying debris and the like.

[0046] As described above, the saddle-ride type vehicle 10 of the present embodiment is provided with the rear brake lever 64 functioning as a rear brake operator on one of the left and right sides of the handlebars 21 (the left side in this configuration), and the second brake cable 72 extending from the rear brake lever 64 crosses the front frame 19 and is connected to the rear brake device 62 arranged on the left-right opposite side of the rear brake lever 64. With this configuration, the second brake cable 72 can be made shorter than a configuration in which the second brake cable 72 crosses the head pipe 18 from the front and is connected to the rear brake device 62 on the left-right opposite side. By shortening the second brake cable 72, it is possible to suppress the risk of an increase in transmission loss due to an increase in the sliding resistance of the second brake cable 72 and the situation in which the space for arranging parts in front of the head pipe 18 or the like is restricted.

[0047] In addition, since the component arrangement space in front of the head pipe 18 is not restricted by the second brake cable 72, even when the rear brake lever 64 and the second brake cable 72 are added to an existing vehicle, there is no need to change the arrangement or shape of the headlight 51, the meter unit 52, etc. Therefore, the routing structure of the second brake cable 72 configured in this manner is easily applicable to existing vehicles. The front frame 19 corresponds to the "main frame" of the present invention.

[0048] Furthermore, since the second brake cable 72 crosses the front frame 19 from below, the foot straddling portion 33M above the front frame 19 is not restricted by the second brake cable 72, making it easier to ensure a wide foot straddling space.

[0049] In addition, the power unit 12, which is a drive source, is located below the main frame 19, and the throttle body 36, which is another vehicle component, is disposed between the second brake cable 72 and the power unit 12. This makes it easier to suppress the thermal effect from the power unit 12 to the second brake cable 72. Note that a vehicle component other than the throttle body 36 may be disposed between the second brake cable 72 and the power unit 12.

[0050] Further, the second brake cable 72 has an upstream portion 72A extending from the rear brake lever 64 side along the front frame 19, a straddling portion 72B straddling the front frame 19, and a downstream portion 72C located downstream of the straddling portion 72B, and has only one second cable holding member 82 that holds the downstream portion 72C on the front frame 19 behind the power unit 12 that is the drive source. With this configuration, the second brake cable 72 can be easily arranged along the front frame 19 in a path that is nearly straight, and even if the swing arm 16 swings up and down, the second brake cable 72 can be easily moved up and down in accordance with the up and down movement of the swing arm 16 without bending the second brake cable 72 significantly. This shortens the second brake cable 72, which is advantageous in reducing transmission loss and securing space for arranging other components, and is also advantageous in discharging rainwater attached to the second brake cable 72.

[0051] Furthermore, the second cable holding member 82 makes it easier to arrange the second brake cable 72 away from the power unit 12 and the like, and makes it easier to avoid contact between the second brake cable 72 and other components. If the second cable holding member 82 were positioned forward of the rear end of the power unit 12, there would be a greater risk that the second brake cable 72, which is located downstream of the second cable holding member 82, would come into contact with the power unit 12.

[0052] In this embodiment, the drive chain 12CN is used as a driving force transmission member connecting the power unit 12 and the rear wheel 15, so the axle 15a of the rear wheel 15 is configured to be adjustable rearward to accommodate cases in which the drive chain 12CN is stretched. Therefore, it is preferable that the second brake cable 72 located downstream of the second cable holding member 82 has an appropriate amount of slack to allow the position of the axle 15a to be adjusted. In this configuration, even if such slack is provided, the slack is located behind the power unit 12, so that the second brake cable 72 can be effectively prevented from coming into contact with the power unit 12.

[0053] In addition, since the second cable holding member 82 is disposed on the front-to-rear width of the pivot shaft 22 in a side view of the vehicle body, the second brake cable 72 can be easily disposed along the swing arm 16 that swings up and down without significantly bending the second brake cable 72, which is advantageous in shortening the second brake cable 72. In addition, the second brake cable 72 can be routed by utilizing dead space, making it easier to ensure a space for the legs to straddle the cable.

[0054] In this embodiment, the power unit 12 is an internal combustion engine, but is not limited to an internal combustion engine and may be a drive motor. In other words, the saddle-ride type vehicle 10 may be an electric vehicle. In the case of a drive motor, the drive motor itself has a bulging shape that bulges upward. By arranging the second brake cable 72 to straddle the front frame 19 from below, in front of the drive motor, a separation distance between the drive motor and the second brake cable 72 can be secured, and the thermal effect from the drive motor to the second brake cable 72 can be easily suppressed.

[0055] [Other embodiments] 6 is a side view of a saddle-ride type vehicle 10 according to another embodiment of the present invention. The same structures as those in the above-described embodiment are denoted by the same reference numerals, and duplicated explanations will be omitted where appropriate. For convenience of explanation, the above-described embodiment will be referred to as the "first embodiment," and the other embodiment will be referred to as the "second embodiment." The second embodiment differs from the first embodiment in that a storage box 91 is disposed in a part of the body frame 11, below the seat 17, and in that a second brake cable 72 straddles the front frame 19 from above. In the second embodiment, both the front braking device 61 and the rear braking device 62 are drum brakes.

[0056] FIG. 7 is a diagram showing the rear part of the front frame 19 together with the surrounding structure, viewed obliquely from above. 6 and 7, the front frame 19 extends rearward and downward from the head pipe 18 along the center of the vehicle width, below the seat 17, and to the vicinity of the rear wheel 15. A pair of left and right rear frames 20 are joined to the front-rear intermediate portion of the front frame 19.

[0057] The pair of left and right rear frames 20 extend left and right from the left and right side surfaces of the front frame 19, then extend rearward and upward via bent portions 20K that bend rearward and upward. The rear frames 20 also function as seat frames. A reinforcing plate 20P is joined to the bent portions 20K, and a cross frame 20C is joined to bridge the bent portions 20K in the vehicle width direction. The reinforcing plate 20P and the cross frame 20C reinforce the rear frame 20, and the rigidity of the body frame 11 is improved.

[0058] Fig. 8 is a diagram showing the storage box 91 together with the surrounding structure from diagonally above. In Fig. 8, a helmet 92 is stored in the storage box 91. 8, the storage box 91 is disposed on the rear of the front frame 19 and on the front of the pair of left and right rear frames 20. A fuel tank 29 is supported on the rear frame 20 behind the storage box 91. The seat 17 is disposed above the storage box 91 and the fuel tank 29 so as to be able to open and close freely, and the weight of the seat 17 is supported by the rear frame 20.

[0059] The pair of left and right pillion steps 38 are foldably supported on rear ends of stays 38S extending rearward and downward from rear portions of the pair of left and right rear frames 20. In this embodiment, as in the above embodiment, a rear brake lever 64 functioning as a rear brake operator is provided on the left side of the handlebar 21, and an upstream portion 72A of the second brake cable 72 extends rearwardly and downwardly from the rear brake lever 64 side, passing over the left side of the head pipe 18 along the left side of the front frame 19, and is not disposed in front of the head pipe 18. In addition, the throttle wire 41, the harness 44 and the first brake cable 71 are disposed in substantially the same manner as in the above embodiment.

[0060] As shown in FIGS. 7 and 8, the second brake cable 72 passes above the front frame 19 from the location of the first cable holding member 81 and is routed to the right side of the front frame 19. 9 is a side cross-sectional view showing the second brake cable 72 on the front frame 19 together with the surrounding configuration. As shown in FIG 9, in the second embodiment, the second brake cable 72 (corresponding to the straddling portion 72B) extends above the front frame 19, rearward of the crankcase 23 and forward of the bent portion 20K of the rear frame 20.

[0061] In other words, the straddling portion 72B of the second brake cable 72 is between the pair of left and right rear frames 20, and crosses the front frame 19 through the space S that is open in the height direction between the front frame 19 and the storage box 91.

[0062] The second brake cable 72 straddles the front frame 19 from above, and is then held by a second cable holding member 82 provided at the rear part of the front frame 19. The second brake cable 72 then passes between the right swing arm 16 and the rear wheel 15, and is connected to the rear brake device 62. 7, a brake guide 85 that guides the second brake cable 72 is provided on the right swing arm 16. This brake guide 85 is disposed on the inner side in the vehicle width direction than the pillion step 38, has a loop portion through which the second brake cable 72 passes, and restricts the movement range of the second brake cable 72 within the range of this loop portion.

[0063] In this manner, in this embodiment as well, similar to the above embodiment, the rear brake lever 64 functioning as a rear brake operator is provided on one of the left and right sides of the handlebar 21, and the second brake cable 72 extending from the rear brake lever 64 side crosses the front frame 19 and is connected to the rear brake device 62 arranged on the opposite left and right side of the rear brake lever 64. This allows the second brake cable 72 to be shortened, similar to the above embodiment, and provides various effects such as reducing transmission loss and being advantageous in securing space for arranging other components.

[0064] In addition, because the second brake cable 72 crosses the front frame 19 from above, the space for arranging components below the front frame 19 is not restricted by the second brake cable 72. This improves the freedom of layout of the components below the front frame 19.

[0065] Moreover, the second brake cable 72 crosses the front frame 19 through a space S (see FIG. 9) that is open in the vertical direction between the front frame 19 and the storage box 91. With this configuration, the second brake cable 72 can be arranged by utilizing the space S, which is the dead space between the front frame 19 and the storage box 91. As a result, the space of the foot straddle section 33M above the front frame 19 is not restricted by the second brake cable 72, making it easier to ensure a wide foot straddle space.

[0066] In addition, the second brake cable 72 crosses the front frame 19 through the space S that is left between the front frame 19, the storage box 91, and the rear frame 20 that functions as a seat frame. This allows the second brake cable 72 to be arranged by utilizing the space S that is the dead space left between the front frame 19, the storage box 91, and the rear frame 20, making it easier to ensure a wide foot straddle space above the front frame 19.

[0067] The second brake cable 72 does not have to be limited to the configuration in which it is arranged to straddle the front frame 19 from above through the space S. For example, as shown in Fig. 10, the second brake cable 72 may be arranged to straddle the front frame 19 from above in front of the storage box 91. In this case, the storage box 91 can be arranged closer to the front frame 19, and the position of the storage box 91 can be lowered to facilitate easier ingress and egress.

[0068] Also in the second embodiment, similarly to the above-described embodiment, the second brake cable 72 has an upstream portion 72A extending from the rear brake lever 64 side along the front frame 19, a straddling portion 72B straddling the front frame 19, and a downstream portion 72C located downstream of the straddling portion 72B, and has a second cable holding member 82 that holds the downstream portion 72C to the front frame 19 behind the power unit 12 which is the drive source. This shortens the second brake cable 72, which is advantageous in reducing transmission loss and ensuring space for arranging other components.

[0069] 7, in the second embodiment, the second cable holding member 82 is disposed rearward of the front-to-rear width of the pivot shaft 22. However, the present invention is not limited to this configuration, and the second cable holding member 82 may be disposed on the front-to-rear width of the pivot shaft 22 in a side view of the vehicle body, as in the first embodiment.

[0070] The above-described embodiment shows one aspect of the present invention, and the present invention is not limited to the above-described embodiment, and the configuration of details, etc. may be changed as appropriate. For example, the second cable holding member 82 is provided at the rear of the front frame 19, but it may be provided on the body frame 11 other than the front frame 19. In addition, the present invention has been described as being applied to a motorcycle shown in FIG. 1 and other figures, but it is not limited to this, and the present invention may be applied to any saddle-ride type vehicle. The saddle-ride type vehicle is not limited to a two-wheeled vehicle, and may be a three-wheeled vehicle, a four-wheeled vehicle, or the like.
