As shown in FIGS. 4 and 5, in the pipe connection portion provided on the upper surface of the ABS modulator 71, the connection fitting 74a of the input-side brake piping 74 and the connection fitting 75a of the output-side brake piping 75 are bolts 76 respectively. Is attached. A screw hole is formed in the pipe connection, and a bolt 76 is screwed into the screw hole. A brake fluid passage is formed in the bolt 76 itself, and the inside of the ABS modulator 71 is communicated with the input-side brake pipe 74 and the output-side brake pipe 75 through the bolt 76, respectively.
The input-side brake pipe 74 extends from the ABS modulator 71 to the head pipe 15 and one of the (right) fork pipes 26 and passes above the bottom bridge 28 to the handle 29 (see FIG. 1). The output-side brake pipe 75 extends forward from the ABS modulator 71 below the input-side brake pipe 74. Furthermore, the output-side brake piping 75 is curved between the head pipe 15 and one of the fork pipes 26 (right side) while passing over the bottom bridge 28 and curved downward and supported by the piping support 68 Ru.

Piping supports 68 are provided at the end of a support bracket 65 attached by bolts 64 to the front of the bottom bridge 28.
From the ABS modulator 71 in the output side brake pipe 75 to the pipe support 68, an upper curved portion 75X is formed which is curved in a U-shape or a J-shape.
The upper curved portion 75X is disposed above, in front of, and below the bottom bridge 28, respectively. In the front view of the vehicle, the upper curved portion 75X extends in the vertical direction along the head pipe 15 and the fork pipe 26, so the space around the front fork 12 can be effectively used. In addition, since the upper curved portion 75X is disposed above, in front of, and below the bottom bridge 28, the interference of the upper curved portion 75X with the bottom bridge 28 can be prevented.

The upper curved portion 75 </ b> X has a front end portion 75 b closer to the inside in the vehicle width direction than the connecting portion side to the ABS modulator 71 and the side supported by the pipe support 68. That is, the front end 75b of the upper curved portion 75X overlaps the head pipe 15 in a front view. In the head pipe 15 and the fork pipe 26, the fork pipe 26 is located forward. For this reason, the upper curved portion 75X is disposed obliquely with respect to the front-rear direction, and the front end portion 75b is brought closer to the center in the vehicle width direction, whereby the upper curved portion 75X is smoothly interposed between the head pipe 15 and the fork pipe 26. Can pass through.
The head pipe 15 is provided with a pair of left and right stoppers 15a projecting laterally from the lower portion, and the bottom bridge 28 is integrally formed with a pair of left and right upper projecting portions 28d which are restricted in rotation against the left and right stoppers 15a. Is formed. That is, the left and right upper protrusions 28d restrict 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) with respect to a vehicle body center line 70 extending in the vertical direction through the center in the vehicle width direction. Further, the piping support 68 is also disposed on one side (right side) with respect to the vehicle body center line 70, similarly to the ABS modulator 71. The upper curved portion 75X is disposed above and in front of the upper protrusion 28d on one side (right side).
In a front view, a headlight harness 89 connected to the headlight 61 (see FIG. 3) is disposed between the down frame 18 and the other (left side) fork pipe 26 and below the bottom bridge 28. ing. The headlight harness 89 is connected to a battery (not shown) disposed at the center of the vehicle body from the headlight 61 through the lower side of the bottom bridge 28.

A portion of the headlight harness 89 located in front of the bottom bridge 28 in detail is supported by a harness support portion 73 provided on the support bracket 65.
The support bracket 65 is composed of a bracket base 83, a pipe support 68, and a harness support 73.
The bracket base 83 is a plate-like member that extends downward from the front surface of the bottom bridge 28 and bends rearward and laterally (rightwardly). One end of the bracket base 83 is attached to the front surface of the bottom bridge 28 with a bolt 64, and a pipe support 68 is attached to the other end of the bracket base 83. The harness support portion 73 is made of a bent wire and is attached to the lower surface of the bracket base 83 by welding.

  As described above, by curving the output-side brake piping 75 in a U-shape or a J-shape between the ABS modulator 71 and the bottom bridge 28, an upper curved portion located between the ABS modulator 71 and the bottom bridge 28 The total length of 75X can be increased. As a result, even when the front fork 12 is steered, it is possible to suppress the reduction of the curvature radius of the curve of the output side brake piping 75, and the durability of the output side brake piping 75 can be improved.

When the upper curved portion 75X is extended in the longitudinal direction of the vehicle, the fork pipe 26 is positioned forward of the head pipe 15, so the distance between the upper curved portion 75X and the head pipe 15 and the fork pipe 26 is shorter. Become. On the other hand, in the present embodiment, the upper curved portion 75X, which is passed between the head pipe 15 and the fork pipe 26, is inclined so as to be positioned gradually inward in the vehicle width direction as it goes to the front of the vehicle. Thus, the distance between the head pipe 15 and the fork pipe 26 and the upper curved portion 75X can be further increased. As a result, even when the front fork 12 is steered, interference between the upper curved portion 75X and the head pipe 15 and the fork pipe 26 can be made difficult.
Further, by arranging the output-side brake piping 75 and the headlight harness 89 separately on the left and right with respect to the center in the vehicle width direction, interference can be avoided, and the output-side brake piping 75 and the headlight harness 89 can be mounted on the vehicle body. Can be placed effectively.

As shown in FIGS. 1, 3 and 5, the motorcycle 1 as a saddle-ride type vehicle includes a head pipe 15, a front fork 12, a front wheel brake 37 as a braking means, and an ABS as a braking force adjustment device. A modulator 71 is provided.
The front fork 12 is steerably supported by the head pipe 15 and a pair of left and right fork pipes 26 are connected by the bottom bridge 28. The front wheel brake 37 applies a braking force to the front wheel 2 pivotally supported by lower end portions of the left and right fork pipes 26. The ABS modulator 71 is connected to the front wheel brake 37 via an output side brake pipe 75 as a pipe.

  The ABS modulator 71 is disposed rearward of the head pipe 15, and an output-side brake pipe 75 extending from the ABS modulator 71 extends forward above the bottom bridge 28 and curves and extends rearward to have a U-shape in a side view Will be routed to The ABS modulator 71 and a pipe support 68 as a pipe support for supporting the output-side brake pipe 75 are disposed on the same side in the vehicle width direction with respect to the center in the vehicle width direction.

  According to this configuration, the output-side brake piping 75 together with the ABS modulator 71 and the piping support 68 is arranged in a U-shape in a side view around the bottom bridge 28 and in one side in the vehicle width direction. A compact layout is possible in the vehicle width direction. Thereby, a clear piping layout around the bottom bridge 28 can be realized. Further, by arranging the output-side brake piping 75 in a U-shape in a side view, the swing width of the output-side brake piping 75 due to steering (in particular, the swing width in the vehicle width direction) can be suppressed, and a light steering operation can be realized. .

Also, as shown in FIG. 5, the pipe support 68 is supported below the bottom bridge 28.
With this configuration, it is possible to eliminate the pipe support portion of the output side brake pipe 75 to the vehicle body behind the head pipe 15 (that is, between the ABS modulator 71 and the head pipe 15). Further, by eliminating the pipe support portion at the rear of the head pipe 15, the influence of the output side brake pipe 75 on steering is suppressed, and the light steering wheel 29 (see FIG. 1) can be arranged.
In addition, since the output-side brake piping 75 is wired obliquely to the longitudinal direction of the vehicle body, the space around the front fork 12 (specifically, the space 95R) can be effectively used, and It can be made compact.
