However, as engines become larger, it may not be possible to secure space inside the main frame to route the brake piping. Even in these cases, the brake piping is exposed on the vehicle exterior, so it is necessary to ensure the protection of the brake piping and the aesthetic appearance of the vehicle. Therefore, there is room for improvement in the routing of brake piping in conventional saddle-ride vehicles.

The present invention provides a saddle-type vehicle that ensures the protection of the brake piping while minimizing the deterioration of the vehicle's aesthetic appearance.

The saddle-type vehicle according to the first aspect of the present invention includes a steering unit (20) having a front fork (21) that supports a front wheel (2) and steers the front wheel (2), a head pipe (11) that supports the steering unit (20), and a body frame (10) having a main frame (12) that extends rearward from the head pipe (11), an engine (31) that is disposed below the main frame (12) in a side view and has a cylinder head (33b), a radiator (41) that is disposed between the front fork (21) and the cylinder head (33b), a radiator hose (56) that connects the radiator (41) and the engine (31) and passes above the cylinder head (33b) in a side view, and a brake pipe (75) that is disposed between the main frame (12) and the radiator hose (56).

According to the first aspect, the brake piping is arranged so as to be sandwiched between the main frame and the radiator hose, making the brake piping less noticeable. In particular, by arranging the brake piping along the main frame and the radiator hose, the sense of uniformity of the arrangement of the rod-shaped members is enhanced, making the brake piping even less noticeable. Moreover, since the brake piping is covered by the main frame and the radiator hose, the protective performance of the brake piping can be ensured. Therefore, the deterioration of the aesthetic appearance of the vehicle can be suppressed while the protective performance of the brake piping is ensured.

The saddle-ride type vehicle according to the second aspect of the present invention is the saddle-ride type vehicle according to the first aspect, further comprising a clutch cable (37) connected to a clutch operator operated by the driver, and the brake pipe (75) may overlap the clutch cable (37) in a side view.

According to the second aspect, the rod-shaped brake piping and clutch cable are arranged so that they overlap each other, which enhances the sense of unity in the arrangement of the rod-shaped members and makes the brake piping even less noticeable.

The saddle-ride vehicle according to the third aspect of the present invention is the saddle-ride vehicle according to the second aspect, in which the brake pipe (75) is disposed on the inside in the vehicle width direction relative to the clutch cable (37).

According to the third aspect, the brake piping is covered by the clutch cable, which has a relatively good appearance, making the brake piping even less noticeable and protecting the brake piping with the clutch cable.

The saddle-ride vehicle according to the fourth aspect of the present invention is the saddle-ride vehicle according to the second or third aspect, in which the clutch cable (37) may be clamped to a member (59) fixed to the radiator hose (56).

According to the fourth aspect, the clutch cable can be securely held between the main frame and the radiator hose, achieving the above-mentioned effects.

The saddle-ride type vehicle according to the fifth aspect of the present invention is a saddle-ride type vehicle according to any one of the second to fourth aspects, in which the clutch cable (37) may be clamped to the outside of the radiator hose (56).

The fifth aspect prevents the clutch cable from interfering with the main frame, and also ensures space for routing the brake piping inside the clutch cable.

The saddle-ride vehicle according to the sixth aspect of the present invention is a saddle-ride vehicle according to any one of the second to fifth aspects, in which the brake pipe (75) may be clamped to the main frame (12) behind the position where the clutch cable (37) is clamped.

According to the sixth aspect, the brake pipe can be fixed at a position close to the fixing point of the clutch cable, thereby suppressing interference between the brake pipe and the clutch cable.

The saddle-ride vehicle according to the seventh aspect of the present invention is a saddle-ride vehicle according to any one of the first to sixth aspects, further comprising a clip (99A) for fixing the brake pipe (75), and the clip (99A) may be inserted into a through hole (12e) formed in the main frame (12).

According to the seventh aspect, the clip can be fixed directly to the main frame, so the brake piping can be fixed lightly and securely without using any parts other than the clip.

The present invention provides a saddle-type vehicle that ensures the protection of the brake piping while minimizing the deterioration of the vehicle's aesthetic appearance.

The intermediate portion 91m is disposed on the inner side of the intermediate portion 83m of the first brake pipe 83 and the clutch cable 37 in the vehicle width direction, and is covered by the intermediate portion 83m of the first brake pipe 83 and the clutch cable 37 from the outer side in the vehicle width direction (see also FIG. 5).

As shown in Figures 6 and 7, the rear portion 91r is connected to the rear end of the intermediate portion 91m. The rear portion 91r extends from the rear end of the intermediate portion 91m, which is located in the space below the rear portion 12d of the main frame 12, to a position on the inside in the vehicle width direction of the main frame 12, and is connected to the ABS modulator 70, which is located rearward and on the inside in the vehicle width direction of the rear end of the intermediate portion 91m.

The front portion 91f is connected to the front end of the middle portion 91m. The front portion 91f extends from the front end of the middle portion 91m inward and forward in the vehicle width direction, then bends forward and downward, extending to a position on the inner side of the rear gusset 17 and the down frame 14 in the vehicle width direction, and connects to a second piping joint 96 located forward and below the front end of the middle portion 91m.

As shown in FIG. 2, the pair of second brake hoses 93 and third brake hoses 94 are made of, for example, synthetic resin or metal mesh, and are flexible, similar to the first brake hose 81. The second brake hoses 93 are provided in a one-to-one correspondence with the left and right brake calipers 67 (see FIG. 1), and extend from each brake caliper 67 and connect to the third piping joint. The third brake hose 94 extends upward from one end connected to the third piping joint, passing behind the front fork 21 and in front of the radiator 41 in a side view, and connects to the second piping joint 96 (see FIG. 6).

As shown in FIG. 6, the first brake pipe 83 and the second brake pipe 91 are clamped to the vehicle body frame 10 by a first clip 99A. The first clip 99A is made of resin. The first clip 99A is fixed to the right main frame 12. The first clip 99A clamps the middle portion 83m of the first brake pipe 83 and the middle portion 91m of the second brake pipe 91 to the right main frame 12 behind the clamper 59 (also see FIG. 7).

FIG. 8 is a cross-sectional view taken along line VIII-VIII in FIG.
8, the first clip 99A is engaged with the main frame 12 by being directly inserted into a through hole 12e formed in the main frame 12. The first clip 99A holds the first brake pipe 83 and the second brake pipe 91 aligned in the vehicle width direction below the main frame 12.

As shown in FIG. 6, the first brake pipe 83 and the second brake pipe 91 are bound together by a second clip 99B. The second clip 99B is made of resin. The second clip 99B binds the front portion 83f of the first brake pipe 83 and the front portion 91f of the second brake pipe 91 in front of the clamper 59 (see FIG. 2).

As described above, the motorcycle 1 of this embodiment includes the radiator hose 56 that connects the radiator 41 and the engine 31 and passes above the cylinder head 33b in a side view, and the brake pipes 83, 91 that are arranged between the main frame 12 and the radiator hose 56. With this configuration, the brake pipes 83, 91 are arranged so as to be sandwiched between the rear part 12d of the main frame 12 and the parallel part 56a of the radiator hose 56, so that the brake pipes 83, 91 can be made less noticeable. In particular, by arranging the brake pipes 83, 91 along the rear part 12d of the main frame 12 and the parallel part 56a of the radiator hose 56, the sense of unity of the arrangement of the rod-shaped members (the main frame 12, the radiator hose 56, and the brake pipes 83, 91) is enhanced, and the brake pipes 83, 91 can be made even less noticeable. Moreover, because the brake pipes 83, 91 are covered by the main frame 12 and the radiator hose 56, the protection performance of the brake pipes 83, 91 can be ensured. Therefore, the protection performance of the brake pipes 83, 91 can be ensured while preventing a decrease in the aesthetic appearance of the vehicle.

The brake pipes 83, 91 overlap the clutch cable 37 in a side view. With this configuration, the rod-shaped brake pipes 83, 91 and the clutch cable 37 are arranged so that they overlap each other, which enhances the sense of unity in the arrangement of the rod-shaped members and makes the brake pipes 83, 91 even less noticeable.

The brake pipes 83, 91 are positioned inward in the vehicle width direction from the clutch cable 37. With this configuration, the brake pipes 83, 91 are covered by the clutch cable 37, which has a relatively good appearance, making the brake pipes 83, 91 even less noticeable and protecting them from the clutch cable 37.

The clutch cable 37 is clamped to a clamper 59 fixed to the radiator hose 56. With this configuration, the clutch cable 37 is securely held between the main frame 12 and the radiator hose 56, achieving the above-mentioned effects.

The clutch cable 37 is clamped by a clamper 59 on the outside of the radiator hose 56 in the vehicle width direction. This configuration prevents the clutch cable 37 from interfering with the main frame 12, and also ensures space for routing the brake pipes 83, 91 inside the clutch cable 37.

The brake pipes 83, 91 are clamped to the main frame 12 behind the clamper 59, and the clutch cable 37. With this configuration, the brake pipes 83, 91 can be fixed in a position close to the fixing point of the clutch cable 37, so interference between the brake pipes 83, 91 and the clutch cable 37 can be suppressed.

The first clip 99A that clamps the brake pipes 83, 91 is inserted into a through hole 12e formed in the main frame 12. With this configuration, the first clip 99A can be fixed directly to the main frame 12, so the brake pipes 83, 91 can be fixed lightly and securely without using any other members than the first clip 99A.

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, the present invention can be applied to all saddle-ride type vehicles in which a driver straddles the vehicle body, that is, the present invention can be applied not only to motorcycles but also to three-wheeled motor vehicles.

In addition, in the above embodiment, the metal brake pipes 83, 91 are arranged between the main frame 12 and the radiator hose 56, but this configuration is not limited to this. Instead of the brake pipes, a flexible brake hose may be arranged between the main frame and the radiator hose.

In addition, in the above embodiment, the brake piping 75 of the front wheel brake device 60 is arranged between the main frame 12 and the radiator hose 56, but this configuration is not limited to this. The brake piping of the rear wheel brake device may be arranged between the main frame and the radiator hose.

In addition, in the above embodiment, both the upstream piping 80 and the downstream piping 90 are arranged between the main frame 12 and the radiator hose 56, but this configuration is not limited to this. Only one of the upstream piping and the downstream piping may be arranged between the main frame and the radiator hose.

In addition, in the above embodiment, the first piping section 51A of the cooling device 40 adjacent to the brake piping 75 forms a flow path of the cooling water from the engine 31 to the radiator 41, but this configuration is not limited. The piping section of the cooling device adjacent to the brake piping may form a flow path of the cooling water from the radiator to the engine.

In addition, the components in the above-described embodiments may be replaced with well-known components as appropriate without departing from the spirit of the present invention.
