In the present invention, a lower bracket (117) supporting a downward extension (75Y) of the brake pipe (75) may be attached to the bottom bridge (28), and the lower bracket (117) may be fixed to a rear side of the bottom bridge (28) and extend downward.

In the present invention, the wire harness support portion (73) may be arranged along the lower surface (28f) of the bottom bridge (28) and below the lower surface (28f) of the bottom bridge (28).

The brake pipe connected to the brake device and the wire harness connected to the headlight include a portion directed in the front-rear direction below the bridge, the brake pipe and the wire harness are arranged side by side in the vehicle width direction at the portion directed in the front-rear direction, and the brake pipe is fixed to the bridge by means of a bracket, and a harness support portion that supports the wire harness is formed on the bracket. Therefore, the brake pipe and the wire harness include portions extending in the same direction under the bridge, and the wire harness support portion is formed on the bracket supporting the brake pipe, thereby achieving a compact layout of the brake pipe and the wire harness.

In the present invention, the bracket extends from the vehicle body center side to one side in the vehicle width direction, the brake pipe is arranged on the one side in the vehicle width direction with respect to the vehicle body center, the wire harness support portion extends from the bracket to the opposite side in the vehicle width direction, and the wire harness is arranged on the opposite side in the vehicle width direction with respect to the vehicle body center. Therefore, the brake pipe and the wire harness can be separately arranged on the left and right sides, respectively, away from the center of the vehicle body, and the space for routing and fixing them can be separated, so that the space for flexing and the like can be easily obtained.

In the present invention, the brake pipe passes above the bridge to extend in the forward direction, is folded back in the forward direction of the bridge, and passes below the bridge to extend in the rearward direction, and the bracket is arranged below the bridge and supports the brake pipe below the bridge. Thus, the bracket can be arranged in a position which is hardly visible under the bridge, and a space which allows the cable to be routed and flexed can be easily obtained.

In the present invention, the wire harness extends downward from the head lamp, further passes in front of the bridge to extend below the bridge, and is supported in front of the bridge by the wire harness support portion. The wire harness extending downward from the front lamp can be supported by the wire harness support portion without difficulty.

Therefore, the brake pipe can be laid at a position that is hardly visible, and the brake pipe can be efficiently laid by utilizing the space between the top bridge and the bottom bridge and the space below the bottom bridge.

In the present invention, the wire harness support portion extends forward from the bracket, further U-turns to the opposite side in the vehicle width direction to extend rearward, and is formed into a substantially U-shape having a free tip, and the wire harness support portion and the front surface of the bottom bridge form a closed space in a bottom view to support the wire harness. Therefore, the wire harness support portion easily supports the wire harness, and the wire harness can be supported in a simple configuration of the wire harness support portion and the bottom bridge.

In the present invention, the bracket is fixed to the front surface of the bottom bridge so as to extend along the lower surface of the bottom bridge to one side in the vehicle width direction. Thus, the bracket can be fixed to the front surface of the bridge in the front-rear direction, and the fixing direction is substantially perpendicular to the direction of movement of the brake pipe caused by steering. Therefore, the brake pipe can be firmly supported by the bracket, and the bracket can be disposed at a position hardly visible.

In the present invention, a lower bracket supporting the downward extension of the brake pipe is attached to the bottom bridge, and the lower bracket is fixed to the rear side of the bottom bridge and extends downward. Therefore, by supporting the downward extension portion of the brake pipe, the deflection of the brake pipe can be restricted, and the bracket can be disposed at a position that is hardly visible.

The ABS modulator 71 is disposed behind the lower portion of the head pipe 15. The upper end position of the modulator case 72 is lower than the upper surface of the ABS modulator 71, which can provide the modulator case 72 with a space that allows flexibility of an input side brake pipe 74 and an output side brake pipe 75, which will be described later in detail, when the front fork 12 is steered.

The bottom bridge 28 includes a pair of fastening portions 28a that fasten the left and right fork tubes 26. The fork tube 26 is inserted into the fastening portion 28a and tightened by the bolt 66. The ABS modulator 71 is located above a straight line 67 extending perpendicularly to the fork 26 from the lower surface 28b of the fastening portion 28a in side view.

A portion of the ABS modulator 71 is positioned above the bottom bridge 28 in the longitudinal direction of the fork 26.

An input side brake pipe 74 and an output side brake pipe 75 are connected to an upper portion of the ABS modulator 71. The input side brake pipe 74 and the output side brake pipe 75 are provided with

connection fittings

74a and 75a, respectively, on the ends. The

connection fittings

74a and 75a are positioned above the bottom bridge 28 in the longitudinal direction of the fork 26, and are connected to a pair of pipe connections (not shown) provided on the upper surface of the ABS modulator 71, respectively.

The other end portion of the input side brake pipe 74 is connected to a front wheel brake master cylinder 77 provided on the handlebar 29. The other end portion of the output side brake pipe 75 is connected to a brake caliper 37b (see fig. 1) provided on the lower end portion of the front fork 12 (more specifically, the fork tube 26).

The intermediate portion of the output side brake pipe 75 is supported at least by the pipe support member 68 located below the bottom bridge 28 and the pipe support member 69 located further below the pipe support member 68. The rear protrusion 28c is integrally formed with the bottom bridge 28, and the pipe bracket 78 is attached to a side surface of the rear protrusion 28c by means of the bolt 58. The pipe support 69 is attached to the lower end portion of the pipe bracket 78 by means of the bolt 59, and the output side brake pipe 75 is supported by the pipe support 69.

The output side brake pipe 75 extends forward (more specifically, diagonally forward and upward) from the upper portion of the ABS modulator 71, and then bends downward. The output side brake pipe 75 is bent further back and reaches the pipe support 68 below the bottom bridge 28. Thus, the upper part of the output side brake pipe 75 extends in a U-or J-shape in side view and is arranged to roll up the bottom bridge 28.

An ignition coil 81 attached to the right side surface of the gusset 21 is arranged above the ABS modulator 71.

More specifically, the headlight harness 89 extends downward from the lower rear of the headlight 61 and curves further rearward to pass under the bottom bridge 28. Also, the headlight harness 89 extends diagonally upward and rearward below the bottom bridge 28, and reaches the battery through one side (left side) of the lower frame 18.

Fig. 4 is a perspective view showing the routing structure of the output side brake pipe 75 and the headlight harness 89. Fig. 5 is a front view showing the routing structure of the output side brake pipe 75 and the headlight harness 89.

As shown in fig. 4 and 5, a connection fitting 74a of the input side brake pipe 74 and a connection fitting 75a of the output side brake pipe 75 are attached to a pipe connection portion provided on an upper surface of the ABS modulator 71 by means of bolts 76. A threaded hole is formed on the pipe connecting portion, and a bolt 76 is attached to the threaded hole by means of a screw. A brake fluid passage is formed in the bolt 76 itself, and the inside of the ABS modulator 71 communicates with the input side brake pipe 74 and the output side brake pipe 75 via the bolt 76.

An input side brake pipe 74 extends from the ABS modulator 71 and passes over the bottom bridge 28 between the head pipe 15 and one of the fork tubes 26 (the right side). The input side brake pipe 74 extends toward the handlebar 29 (see fig. 1). The output side brake pipe 75 extends forward from the ABS modulator 71 below the input side brake pipe 74. Also, the output side brake pipe 75 passes over the bottom bridge 28 between the head pipe 15 and one of the fork pipes 26 (right side). The output side brake pipe 75 is bent downward and rearward and supported by the pipe support 68.

The tube support 68 is provided at the end of the support bracket 65, the support bracket 65 being attached to the front surface of the bottom bridge 28 by means of the bolts 64.

From the ABS modulator 71 to the tube support 68, the output side brake tube 75 is configured as an upper bent portion 75X bent in a U-shape or J-shape.

Upper bends 75X are disposed above, forward of, and below bottom bridge 28, away from bottom bridge 28. The upper bent portion 75X extends in the up-down direction along the head pipe 15 and the fork pipe 26 in the front view of the vehicle, and the space around the front fork 12 can be effectively used. The upper bent portions 75X are arranged above, in front of, and below the bottom bridge 28, away from the bottom bridge 28, so that a space that allows the upper bent portions 75X to flex is available.

The front end portion 75b side of the upper bent portion 75X is located on the inner side in the vehicle width direction with respect to the connection portion side of the ABS modulator 71 and the side supported by the tube support 68. More specifically, in the front view, the front end portion 75b of the upper bent portion 75X overlaps with the head pipe 15. Of the front end tube 15 and the fork tube 26, the fork tube 26 is positioned forward. Therefore, the upper bent portion 75X can be arranged obliquely with respect to the front-rear direction, and the front end portion 75b can be closer to the center in the vehicle width direction. Thus, the upper bent portion 75X can be smoothly placed between the head pipe 15 and the branch pipe 26.

The head pipe 15 is provided with a pair of left and right stoppers 15a protruding laterally from the lower portion. A pair of left and right upper projections 28d are integrally formed on the bottom bridge 28. The left and right upper protruding portions 28d contact the left and right stoppers 15a, and restrict rotation. Therefore, the left and right upper protrusions 28d limit the steering angle of the front fork 12 and the front wheel 2 (see fig. 1).

As shown in fig. 5, the ABS modulator 71 is disposed on one side (right side) of a vehicle body center line 70, which vehicle body center line 70 extends through the center in the vehicle width direction in the up-down direction. The tubular support member 68 is also disposed on one side (right side) of the vehicle body center line 70 just like the ABS modulator 71. The upper bent portion 75X is arranged above and forward of one (right side) of the upper protruding portions 28d, away from the protruding portions 28 d.

A downward extension 75Y of the output side brake pipe 75 is supported by the pipe support member 69, and the downward extension 75Y is bent to extend downward behind the pipe support member 68.

In the front view, a headlight harness 89 connected to the headlight 61 (see fig. 3) is arranged between the lower frame 18 and the other fork tube 26 (left side) and below the bottom bridge 28. The headlight harness 89 extends downward from the headlight 61 and further extends rearward by passing in front of and below the bottom bridge 28, and the headlight harness 89 is connected to a battery (not shown) arranged on the vehicle body center portion.

The middle of the headlight harness 89 (particularly, the portion located forward of the bottom bridge 28) is supported by the harness support portion 73 provided on the support bracket 65.

The support bracket 65 includes a bracket base 83, a tube support 68, and a harness support 73.

The bracket base 83 is made of a plate-like member that extends downward from the front surface of the bottom bridge 28 and is bent rearward and then bent to the side (toward the right side). One end of the bracket base 83 is attached to the front surface of the bottom bridge 28 by means of the bolt 64, and the pipe support 68 is attached to the other end of the bracket base 83. The wire harness support portion 73 is made of a bent wire material attached by being welded to the lower surface of the bracket base 83.

As described above, output side brake pipe 75 can be bent in a U-shape or J-shape between ABS modulator 71 and bottom bridge 28, and the length of entire upper bent portion 75X between ABS modulator 71 and bottom bridge 28 can be increased. This can suppress a decrease in the radius of curvature of the bend of the output side brake pipe 75 even when the front fork 12 is steered, and can improve the durability of the output side brake pipe 75.

When the upper bent portion 75X extends in the front-rear direction of the vehicle, the fork tube 26 is positioned in front of the head tube 15. Therefore, the distance from the upper bent portion 75X to the head pipe 15 and the fork 26 becomes shorter. On the other hand, in the present embodiment, the upper bent portion 75X that passes through the head pipe 15 and the fork tube 26 is gradually inclined inward in the vehicle width direction toward the vehicle front. Therefore, the distance from the head tube 15 and the fork tube 26 to the upper curved portion 75X can be larger. Therefore, even when the front fork 12 is steered, a space that allows the output side brake pipe 75 to flex can be obtained.

Also, the output side brake pipe 75 and the headlight harness 89 are arranged on the left and right sides of the center in the vehicle width direction, respectively. Therefore, a space that allows the output side brake pipe 75 to flex and the headlight harness 89 to flex can be obtained, and the output side brake pipe 75 and the headlight harness 89 can be efficiently arranged on the vehicle body.

As shown in fig. 3 to 5, the output side brake pipe 75 as a brake pipe passes over the bottom bridge 28 as a bridge to extend forward, turns back in front of the bottom bridge 28, and passes under the bottom bridge 28 to extend rearward. The support bracket 65 as a bracket is disposed below the bottom bridge 28 and supports the output side brake pipe 75 below the bottom bridge 28.

According to this configuration, the support bracket 65 can be arranged below the bottom bridge 28 to be in a position hardly visible, and a space allowing the output side brake pipe 75 to be laid and flexed can be easily obtained.

Fig. 6 is a main portion front view showing the bottom bridge 28 and its surroundings, and fig. 7 is a main portion perspective view showing the bottom bridge and its surroundings.

As shown in fig. 6, the support bracket 65 attached to the center of the bottom bridge 28 in the vehicle width direction extends downward and rearward, then extends to one side (right side), and supports the output side brake pipe 75 via the pipe support member 68.

The output side brake pipe 75 and the headlight harness 89 extend downward from the lower edge 42b of the front cover 42 below the headlight 61, and pass in front of and below the bottom bridge 28 to extend rearward.

As shown in fig. 7, the wire harness support portion 73 of the support bracket 65 includes an attachment portion 73a, a first curved portion 73b, a second curved portion 73c, a straight portion 73d, and an end bent portion 73 e.

The attachment portion 73a is a portion attached to the lower surface 83a of the bracket base 83 by welding. The first curved portion 73b is a portion that is first curved forward from the end portion of the attachment portion 73a and is further curved to one side (right side) in the vehicle width direction. The second bent portion 73c is first bent forward from the end portion of the second bent portion 73c, and is further bent to the opposite side (left side) in the vehicle width direction and bent backward. The straight portion 73d is a portion extending rearward from the end of the second curved portion 73 c. The end-folded portion 73e is a portion that is bent to a greater degree than the U-shaped corner from the rear end of the straight portion 73 d.

The headlight harness 89 passes through a space 111 surrounded by the first curved portion 73b, the second curved portion 73c, and the flat portion 73d of the harness support portion 73. By providing such a harness support portion 73, the headlight harness 89 can be prevented from being excessively deflected in the forward direction and the vehicle width direction. The bottom bridge 28 can prevent the headlight harness 89 from being excessively deflected in the rearward direction.

As shown in fig. 6 and 7, the support bracket 65 (particularly, the wire harness support portion 73) is arranged to close a gap (see fig. 3) below the headlight 61 (more particularly, a gap between the lower edge 42b of the front cover 42 and the bottom bridge 28) so that the gap can become inconspicuous.

Fig. 8 is a view seen from the lower surface 28f of the bottom bridge 28 in the axial direction of the steering shaft 113.

The bottom bridge 28 is formed in a V-shape in which the left and right fork tubes 26 are positioned forward relative to the steering shaft 113 in bottom view. On the front surface 28g of the bottom bridge 28 and at the center in the vehicle width direction (more specifically, on the vehicle body center line 70 (see fig. 5)), the front protrusion 28h is integrally formed to extend forward, and the support bracket 65 is attached to the front end surface 28j of the front protrusion 28h by means of the bolt 64. The bolt 64 is disposed on a vehicle body center line 70 (see fig. 5).

The bracket base 83 of the support bracket 65 is formed in a V-shape, an L-shape, or a J-shape in bottom view. The wire harness support portion 73 is bent on a plane along the lower surface 28f of the bottom bridge 28, and is arranged below the lower surface 28f of the bottom bridge 28. Since the wire harness support portion 77 has a simple shape that is bent on a plane, the wire harness support portion 77 can be easily formed, and the cost can be reduced.

The bottom bridge 28 and the wire harness support portion 73 are inclined forward and upward such that the wire harness support portion 73 is positioned forward of the bottom bridge 28 (see fig. 5). Therefore, the headlight harness 89 can be supported in front of the bottom bridge 28 by the harness support portion 73.

The wire harness support portion 73 extends forward relative to the front surface 28g of the bottom bridge 28, and the bottom bridge 28 and the wire harness support portion 73 form an enclosed space 115 in a bottom view.

The output side brake pipe 75 and the headlight harness 89 include front and rear extending

portions

75c, 89c, the front and rear extending

portions

75c, 89c extend forward and rearward, respectively, and are spaced apart in the vehicle width direction, and the front and rear extending

portions

75c, 89 are supported by the pipe support 68 and the harness support portion 73, respectively.

The pipe bracket 78, the pipe support 69, and the bolt 59 constitute a support bracket 117. Since the

edges

78a, 78a on both sides of the pipe bracket 78 are bent and formed in a rib shape, the rigidity of the pipe bracket 78 can be increased. Therefore, even if the pipe bracket 78 extends vertically, flexure associated with vehicle body vibration can be suppressed.

As shown in fig. 3, 7 and 8, a headlight harness 89 as a harness extends downward from the headlight 61, passes in front of the bottom bridge 28 to extend below the bottom bridge 28, and is supported in front of the bottom bridge 28 by a harness support portion 73.

According to this configuration, the headlight harness 89 extending downward from the headlight 61 can be supported by the harness support portion 73 without difficulty.

As shown in fig. 7 and 8, the wire harness support portion 73 extends forward from the support bracket 65, further U-turns to the opposite side in the vehicle width direction to extend rearward, and is formed into a substantially U-shape having a free tip, and the wire harness support portion 73 and the front surface 28h of the bottom bridge 28 form a closed space 115 in a bottom view to support the headlight wire harness 89.

According to this configuration, the harness support portion 73 easily supports the headlight harness 89, and the headlight harness 89 can be supported with a simple configuration of the harness support portion 73 and the bottom bridge 28.

As shown in fig. 5 and 8, the support bracket 65 is fixed to the front surface 28g of the bottom bridge 28 so as to extend to one side in the vehicle width direction along the lower surface 28f of the bottom bridge 28.

According to this configuration, the support bracket 65 can be fixed to the front surface 28g of the bottom bridge 28 in the front-rear direction, and the fixing direction is substantially perpendicular to the moving direction (mainly the vehicle width direction) of the output side brake pipe 75 caused by steering. Therefore, the output side brake pipe 75 can be firmly supported by the support bracket 65, and the support bracket 65 can be disposed at a position that is hardly visible.

As shown in fig. 3, 5 and 8, a support bracket 117 as a lower bracket supporting the downward extension portion 75Y of the output side brake pipe 75 is attached to the bottom bridge 28, and the support bracket 117 is fixed to the rear side of the bottom bridge 28 and extends downward.

According to this configuration, by supporting the downward extension portion 75Y of the output side brake pipe 75, the deflection of the output side brake pipe 75 can be restricted, and the support bracket 117 can be disposed at a position that is hardly visible.

As shown in fig. 7 and 8, the wire harness support portion 73 is arranged along the lower surface 28f of the bottom bridge 28 and below the lower surface 28f of the bottom bridge 28.

According to this configuration, the harness support portion 73 can be easily formed into a simple shape, and the headlight harness 89 can be supported while allowing a flexing space of the headlight harness 89 to be maintained by separating the harness support portion 73 downward from the bottom bridge 28.

Fig. 9 is a sectional view taken along line IX-IX of fig. 3, showing a section cut parallel to the axis 90 of the head tube 15 in fig. 3.

In fig. 9, the ABS modulator 71 is positioned above the bottom bridge 28, and the ABS modulator 71 overlaps one (right side) of the left and right forks 26.

A space 95R is formed between the top bridge 27 and the bottom bridge 28 and between one (right side) of the head pipe 15 and the fork pipe 26. A space 95L is formed between the head pipe 15 and the other fork 26 (left side).

The output side brake pipe 75 passes through the space 95R, and the headlight harness 89 connected to the headlight 61 (see fig. 1) passes through the space 95L.

Between the bottom bridge 28 and the front fender 48, a space 96R is formed between the lower frame 18 and one of the fork tubes 26 (right side), and a space 96L is formed between the lower frame 18 and the other fork tube 26 (left side).

The output side brake pipe 75 passes through the space 96R, and the headlight harness 89 passes through the space 96L.

As shown in fig. 1, 3 and 8, the motorcycle 1 is a saddle type ride vehicle, and the front fork 12, which is supported by the head pipe 15 in a steerable manner, includes a pair of left and right fork tubes 26 joined by a bottom bridge 28. The front fork 12 rotatably supports the front wheel 2. The headlight 61 is arranged in front of the front fork 12, and the front wheel brake 37 as a braking device is supported by the front fork 12 on one side of the front wheel 2.

The output side brake pipe 75 connected to the front wheel brake 37 and the headlight harness 89 connected to the headlight 61 include front-

rear extending portions

75c, 89c as portions directed in the front-rear direction below the bottom bridge 28. The output side brake pipe 75 and the headlight harness 89 are arranged side by side in the vehicle width direction at the front and rear extending

portions

75c, 89c, and the output side brake pipe 75 is fixed to the bottom bridge 28 by means of the support bracket 65. A harness support portion 73 that supports the headlight harness 89 is formed on the support bracket 65.

According to this configuration, the output side brake pipe 75 and the headlight harness 89 include portions (front-

rear extending portions

75c, 89c) extending in the same direction below the bottom bridge 28. The harness support portion 73 can be formed on the support bracket 65 that supports the output side brake pipe 75, thereby achieving a compact layout of the output side brake pipe 75 and the headlamp harness 89.

As shown in fig. 8, the support bracket 65 (more specifically, the bracket base 83) extends from the vehicle body center side to one side in the vehicle width direction, and the output side brake pipe 75 is arranged on the one side in the vehicle width direction with respect to the vehicle body center. The harness support portion 73 extends from the support bracket 65 (more specifically, the bracket base portion 83) to the opposite side in the vehicle width direction, and the headlight harness 89 is arranged on the opposite side in the vehicle width direction with respect to the vehicle body center.

According to this configuration, the output side brake pipe 75 and the headlight harness 89 can be separately arranged on the left and right sides, respectively, away from the center of the vehicle body, and the space for routing and fixing them can be separated, so that the space for flexing and the like can be easily obtained.

As shown in fig. 3, 5 and 9, the bottom bridge 28 is the bottom bridge 28 among the upper and lower pair of top and

bottom bridges

27 and 28 joining the left and right fork tubes 26. The output side brake pipe 75 runs along the upper surface 28k and the lower surface 28f of the bottom bridge 28.

According to this configuration, the output side brake pipe 75 can be laid at a position that is hardly visible, and the output side brake pipe 75 can be efficiently laid with the space between the top bridge 27 and the bottom bridge 28.
