In other words, it is easy for the second tube to have an appropriate length. On the other hand, the outer part is shorter than the inner part. Therefore, the air cleaner is arranged at a position close to the throttle body. Thus, it is easy to miniaturize the entire throttle body, second tube, and air cleaner. For example, it is easy to reduce the overall length of the throttle body, second tube, and air cleaner in the vertical direction of a saddle-type vehicle. In summary, while the second tube has an appropriate length, the entire throttle body, second tube, and air cleaner are compact.

[0027] In the saddle-type vehicle described above, the inner part preferably curves forward inside the air cleaner which is preferable. Therefore, it is easy to make the inner part longer than the outer part.

For example, all of the through-hole 78 is disposed behind all of the suction port 76. The through-hole 78 does not overlap the suction port 76 in a view from the bottom of the vehicle.

[0701] Although FIG. 16 omits the illustration of the second pipe 43, the second pipe 43 is inserted into the through-hole 78. For this reason, the second pipe 43 penetrates the bottom portion 73. The second pipe 43 penetrates the rear portion 73b of the bottom portion 73.

[0702] FIG. 17 is a front view of the air cleaner 71 and the fuel tank 69. FIG. 17 shows the fuel tank 69 by a dashed line. The air cleaner 71 overlaps the fuel tank 69 in a view from the front of the vehicle. A part of the air cleaner 71 overlaps the fuel tank 69 in a view from the front of the vehicle.

[0703] The air cleaner case 72 overlaps the fuel tank 69 in a view from the front of the vehicle. A part of the air cleaner case 72 overlaps the fuel tank 69 in a view from the front of the vehicle.

[0704] The upper portion 72a overlaps the fuel tank 69 in a view from the front of the vehicle. A part of the upper portion 72a overlaps the fuel tank 69 in a view from the front of the vehicle.

[0705] The lower portion 72b overlaps the fuel tank 69 in a view from the front of the vehicle. A part of the lower portion 72b overlaps the fuel tank 69 in a view from the front of the vehicle.

For example, all of the suction port 76 overlaps the fuel tank 69 in a view from the front of the vehicle.

[0707] 10. Effects of the Embodiment The straddle-type vehicle 1 includes a vehicle body frame 30, an engine 10, an intake pipe 41, an air cleaner 71, a seat 3, and a storage box 25. The engine 10 is fixed to the vehicle body frame 30. The air cleaner 71 is connected to the intake pipe 41. The seat 3 is disposed above the engine 10. The storage box 25 is disposed below the seat 3. The engine 10 has a cylinder head 14. The cylinder head 14 is connected to the intake pipe 41.

[0708] At least a part of the cylinder head 14 overlaps with the seat 3 in a plan view of the vehicle. The air cleaner 71 is disposed above the cylinder head 14, below the seat 3, and in front of the storage box 25. Here, the cylinder head 14 is relatively small. Therefore, the space above the cylinder head 14, below the seat 3, and in front of the storage box 25 is relatively large. Thus, it is easy to appropriately install the air cleaner 71. For example, it is easy to increase the size of the air cleaner 71.

[0709] As described above, the straddle-type vehicle 1 allows for appropriate installation of the air cleaner 71.

[0710] All of the cylinder head 14 overlaps with the seat 3 in a plan view of the vehicle. Therefore, the space above the cylinder head 14, below the seat 3, and in front of the storage box 25 is even larger. Thus, it is even easier to appropriately install the air cleaner 71.

[0711] All of the engine 10 is disposed behind the front end 3a of the seat 3. Therefore, the space above the cylinder head 14, below the seat 3, and in front of the storage box 25 is even larger. Thus, it is even easier to appropriately install the air cleaner 71.

[0712] The air cleaner 71 overlaps with at least a part of the cylinder head 14 in a plan view of the vehicle. Therefore, it is easy to dispose the air cleaner 71 above the cylinder head 14.

[0713] The air cleaner 71 has a portion located in front of the entire cylinder head 14. Therefore, it is even easier to properly install the air cleaner 71.

[0714] The entire air cleaner 71 overlaps with the seat 3 in a plan view of the vehicle. For this reason, it is easy to dispose the air cleaner 71 below the seat 3.

[0715] At least a part of the air cleaner 71 overlaps with the storage box 25 in a front view of the vehicle. For this reason, it is easy to dispose the air cleaner 71 in front of the storage box 25.

[0716] The air cleaner 71 has a portion located in front of the entire engine 10. Therefore, it is even easier to properly install the air cleaner 71.

[0717] The air cleaner 71 has a portion located in front of the entire intake pipe 41. Therefore, it is even easier to properly install the air cleaner 71.

[0718] The intake pipe 41 extends upward from the cylinder head 14. As described above, the air cleaner 71 is disposed above the cylinder head 14. For this reason, it is easy to connect the intake pipe 41 to the air cleaner 71.

[0719] The intake pipe 41 is disposed above the cylinder head 14, below the air cleaner 71, and in front of the storage box 25. For this reason, it is easy to connect the intake pipe 41 to the cylinder head 14. It is easy to connect the intake pipe 41 to the air cleaner 71.

[0720] At least a part of the intake pipe 41 overlaps with the cylinder head 14 in a plan view of the vehicle. For this reason, it is easy to dispose the intake pipe 41 above the cylinder head 14. Therefore, it is even easier to connect the intake pipe 41 to the cylinder head 14.

[0721] At least a part of the intake pipe 41 overlaps with the air cleaner 71 in a plan view of the vehicle. Therefore, it is easy to arrange the intake pipe 41 below the air cleaner 71. Thus, it is even easier to connect the intake pipe 41 to the air cleaner 71.

[0722] At least a part of the intake pipe 41 overlaps with the storage box 25 in a front view of the vehicle. Therefore, it is easy to arrange the intake pipe 41 in front of the storage box 25.

[0723] The intake pipe 41 is arranged below the seat 3. Therefore, it is easy to connect the intake pipe 41 to the air cleaner 71.

[0724] At least a part of the intake pipe 41 overlaps with the seat 3 in a plan view of the vehicle. Therefore, it is easy to arrange the intake pipe 41 below the seat 3. Thus, it is even easier to connect the intake pipe 41 to the air cleaner 71.

[0725] The intake pipe 41 includes a throttle body 54 and a first pipe 42. The first pipe 42 extends from the engine 10 to the throttle body 54. Therefore, it is easy to connect the intake pipe 41 to the cylinder head 14.

[0726] The throttle body 54 is arranged above the cylinder head 14. The throttle body 54 overlaps with the cylinder head 14 in a plan view of the vehicle. Therefore, it is easy for the first pipe 42 to extend from the cylinder head 14 to the throttle body 54.

[0727] The intake pipe 41 includes a second pipe 43. The second pipe 43 extends from the throttle body 54 to the air cleaner 71. Therefore, it is easy to connect the intake pipe 41 to the air cleaner 71.

[0728] The throttle body 54 is disposed below the air cleaner 71. The throttle body 54 overlaps the air cleaner 71 in a plan view of the vehicle. Therefore, it is easy for the second pipe 43 to extend from the throttle body 54 to the air cleaner 71.

[0729] The second pipe 43 penetrates the bottom 73 of the air cleaner 71. The second pipe 43 includes an outer portion 44 and an inner portion 45. The outer portion 44 is a portion of the second pipe 43 located outside the air cleaner 71. The inner portion 45 is a portion of the second pipe 43 located inside the air cleaner 71. The inner portion 45 is longer than the outer portion 44. Therefore, the second pipe 43 is not overly short. In other words, it is easy for the second pipe 43 to have an appropriate length. On the other hand, the outer portion 44 is shorter than the inner portion 45. Therefore, the air cleaner 71 is disposed at a position close to the throttle body 54. Thus, it is easy to miniaturize the entire throttle body 54, the second pipe 43, and the air cleaner 71. For example, it is easy to reduce the overall length of the throttle body 54, the second pipe 43, and the air cleaner 71 in the vertical direction Z. In summary, while the second pipe 43 has an appropriate length, the entire throttle body 54, the second pipe 43, and the air cleaner 71 are compact.

[0730] It is easy for the second pipe 43 to have an appropriate length. Therefore, for example, it is easy to improve the output of the engine 10. It is easy to improve the torque characteristics of the engine 10.

[0731] The inner portion 45 curves forward inside the air cleaner 71. Therefore, it is easy to make the inner portion 45 longer than the outer portion 44.

[0732] The second pipe 43 penetrates the rear portion 73b of the bottom 73 of the air cleaner 71. Therefore, it is easy to curve the inner portion 45 forward inside the air cleaner 71. Thus, it is even easier to make the inner portion 45 longer than the outer portion 44.

[0733] The first pipe 42 extends upward and rearward from the cylinder head 14. For this reason, the first pipe 42 shifts the throttle body 54 and the outer portion 44 rearward. For example, the throttle body 54 and the outer portion 44 are disposed rearward of the first end 41a of the intake pipe 41. Further, the throttle body 54 extends upward from the first pipe 42. The outer portion 44 extends upward from the throttle body 54. For this reason, it is easy for the second pipe 43 to penetrate the rear portion 73b of the bottom 73 of the air cleaner 71.

[0734] The air cleaner 71 has an air inlet 76 for taking in air. The air inlet 76 is disposed forward of the cylinder head 14. For this reason, it is difficult for the air warmed by the engine 10 to reach the air inlet 76. Thus, it is difficult for the air inlet 76 to take in the air warmed by the engine 10. As a result, the temperature of the air taken in by the air inlet 76 is relatively low. In other words, the temperature of the air introduced into the air cleaner 71 by the air inlet 76 is relatively low.

[0735] The air inlet 76 is disposed at the front portion of the air cleaner 71. For this reason, it is easy to dispose the air inlet 76 forward of the cylinder head 14.

[0736] The air inlet 76 takes in the air in front of the air cleaner 71. Here, it is difficult for the air warmed by the engine 10 to reach the area in front of the air cleaner 71. Thus, it is difficult for the air inlet 76 to take in the air warmed by the engine 10. As a result, it is easy for the air inlet 76 to take in air at a relatively low temperature. In other words, it is easy for the air inlet 76 to introduce air at a relatively low temperature into the air cleaner 71.

[0737] The straddle-type vehicle 1 is equipped with a fuel tank 69. The fuel tank 69 is arranged in front of the air cleaner 71. The intake port 76 overlaps with the fuel tank 69 when viewed from the front of the vehicle. Therefore, the fuel tank 69 prevents water, dust, or dirt from entering the intake port 76. Thus, it is easy for the intake port 76 to take in clean air. Even if the structure of the intake port 76 is simple, it is easy for the intake port 76 to take in clean air.

[0738] The engine 10 is classified as a single-cylinder engine. Therefore, it is easy to simplify the configuration of the intake pipe 41.

[0739] The engine 10 is equipped with a crankcase 11. The crankcase 11 is provided behind the cylinder head 14. Therefore, the cylinder head 14 is arranged at substantially the same height position as the crankcase 11. Thus, the cylinder head 14 is arranged at a relatively low position. Accordingly, the space above the cylinder head 14, below the seat 3, and in front of the storage box 25 is larger. Thus, it is even easier to appropriately install the air cleaner 71.

[0740] The cylinder head 14 is smaller than the crankcase 11. Therefore, the space above the cylinder head 14, below the seat 3, and in front of the storage box 25 is larger. Thus, it is even easier to appropriately install the air cleaner 71.

[0741] The engine 10 is equipped with a cylinder body 13. The cylinder body 13 forms a cylinder bore 16. The cylinder body 13 is provided behind the cylinder head 14. Therefore, the cylinder head 14 is arranged at substantially the same height position as the cylinder body 13. Thus, the cylinder head 14 is arranged at a relatively low position. Accordingly, the space above the cylinder head 14, below the seat 3, and in front of the storage box 25 is larger. Thus, it is even easier to appropriately install the air cleaner 71.

[0742] The straddle-type vehicle 1 includes an engine 10, an intake pipe 41, a throttle valve 52, a gearbox 55, a motor 58, a fuel injection device 61, and a fuel pipe 63. The intake pipe 41 is connected to the engine 10. The throttle valve 52 is provided in the intake pipe 41. The gearbox 55 is connected to the throttle valve 52. The motor 58 is connected to the gearbox 55. The motor 58 drives the throttle valve 52 via the gearbox 55. The fuel injection device 61 is attached to the downstream portion of the intake pipe 41. Specifically, the fuel injection device 61 is attached to the portion of the intake pipe 41 from the throttle valve 52 to the engine 10. The fuel pipe 63 has a first end 64. The first end 64 is connected to the fuel injection device 61.

[0743] The gearbox 55 overlaps the first end 64 in a side view of the vehicle. As described above, the gearbox 55 is connected to the throttle valve 52. The first end 64 is connected to the fuel injection device 61. Therefore, it is easy to arrange the throttle valve 52 at a position close to the fuel injection device 61. In other words, it is easy to shorten the portion of the intake pipe 41 from the throttle valve 52 to the fuel injection device 61. The portion of the intake pipe 41 from the throttle valve 52 to the fuel injection device 61 is included in the downstream portion. Therefore, it is easy to shorten the downstream portion.

[0744] The right area AR is an area located to the right of the fuel injection device 61. The left area AL is an area located to the left of the fuel injection device 61. The gearbox 55 is arranged in one of the right area AR and the left area AL. The first end 64 is arranged in the other of the right area AR and the left area AL. Specifically, the gearbox 55 is arranged in the right area AR. The first end 64 is arranged in the left area AL. Therefore, the gearbox 55 and the first end 64 do not interfere with each other. Therefore, it is easy to prevent interference between the gearbox 55 and the fuel pipe 63.

[0745] In summary, it is easy for the straddle-type vehicle 1 to shorten the downstream portion of the intake pipe 41. Furthermore, it is easy for the straddle-type vehicle 1 to prevent interference between the gearbox 55 and the fuel pipe 63.

[0746] As described above, in the straddle-type vehicle 1, the downstream portion of the intake pipe 41 is short. Therefore, the downstream portion has a small volume. More specifically, the downstream portion has an air flow path with a small volume. Thus, for example, it is easy to quickly change the intake air amount of the engine 10 by the throttle valve 52. It is easy to reduce the time lag between the change in the opening degree of the throttle valve 52 and the change in the intake air amount of the engine 10.

[0747] In the straddle-type vehicle 1, the downstream portion of the intake pipe 41 is short. Therefore, the downstream portion has a small volume. Thus, for example, it is difficult for gas to return from the engine 10 to the downstream portion. It is difficult for unburned gas or exhaust gas to flow backward from the combustion chamber to the downstream portion. Therefore, it is difficult for the fuel consumption of the engine 10 to decrease. Further, it is easy to purify the exhaust gas of the engine 10.

[0748] All of the fuel pipes 63 are arranged in the left area AL. Therefore, it is even easier to prevent interference between the gearbox 55 and the fuel pipes 63.

[0749] All of the gearbox 55 is arranged in the right area AR. Therefore, it is even easier to prevent interference between the gearbox 55 and the fuel pipes 63.

[0750] The gearbox 55 overlaps the fuel injection device 61 in a side view of the vehicle. Therefore, it is even easier to arrange the throttle valve 52 at a position close to the fuel injection device 61. Thus, it is even easier to shorten the downstream portion of the intake pipe 41.

[0751] The intake pipe 41 extends upward from the engine 10. The fuel injection device 61 is arranged above the engine 10. The throttle valve 52 is arranged above the fuel injection device 61. Therefore, it is easy to attach the fuel injection device 61 to the downstream portion of the intake pipe 41.

[0752] The throttle valve 52 is arranged at the same height position as the gear box 55. Therefore, it is even easier to arrange the throttle valve 52 at a position close to the fuel injection device 61.

[0753] The fuel injection device 61 extends forward and upward from the intake pipe 41. The gear box 55 extends forward from the throttle valve 52. Therefore, it is easy for the gear box 55 to overlap with the first end 64 in the side view of the vehicle.

[0754] The first end 64 of the fuel pipe 63 extends forward from the fuel injection device 61. It is even easier for the gear box 55 to overlap with the first end 64 in the side view of the vehicle.

[0755] The intake pipe 41 includes a throttle body 54. The throttle body 54 houses the throttle valve 52. Therefore, it is easy to provide the throttle valve 52 in the intake pipe 41. The intake pipe 41 includes a first pipe 42. The first pipe 42 extends from the engine 10 to the throttle body 54. Therefore, the first pipe 42 is included in the downstream portion. The fuel injection device 61 is attached to the first pipe 42. Therefore, it is easy to attach the fuel injection device 61 to the downstream portion.

[0756] The first pipe 42 extends from the engine 10 upward and rearward. Therefore, it is easy to lower the height position of the throttle body 54. In other words, it is easy to reduce the distance in the vertical direction Z between the engine 10 and the throttle body 54.

[0757] The first pipe 42 extends from the engine 10 upward and rearward. Therefore, it is easy for the fuel injection device 61 to extend forward and upward from the first pipe 42.

[0758] The throttle body 54 extends upward from the first pipe 42. Therefore, it is even easier for the gear box 55 to overlap with the first end 64 in the side view of the vehicle.

[0759] The throttle body 54 extends upward from the first pipe 42. Therefore, it is easy for the gearbox 55 to extend forward from the throttle valve 52.

[0760] The engine 10 has an intake passage 17 connected to the first pipe 42. The first pipe 42 extends upward and rearward from the intake passage 17. The intake passage 17 extends downward and rearward from the first pipe 42. Therefore, air smoothly flows from the first pipe 42 into the intake passage 17.

[0761] The motor 58 is disposed in front of the throttle valve 52. Therefore, it is easy to dispose the motor 58 at a position close to the throttle valve 52. Thus, it is easy for the motor 58 to drive the throttle valve 52.

[0762] The motor 58 is disposed above the engine 10. Therefore, the motor 58 and the engine 10 do not interfere with each other.

[0763] The motor 58 is disposed above the first end 64 of the fuel pipe 63. Therefore, the motor 58 and the first end 64 do not interfere with each other.

[0764] The motor 58 is disposed above the fuel injection device 61. Therefore, the motor 58 and the fuel injection device 61 do not interfere with each other.

[0765] The motor 58 overlaps the fuel injection device 61 in a plan view of the vehicle. Therefore, it is easy to dispose the motor 58 at a position close to the fuel injection device 61. As described above, the motor 58 is connected to the gearbox 55. The fuel injection device 61 is connected to the first end 64. Therefore, it is easy to dispose the gearbox 55 at a position close to the first end 64. Thus, it is easy for the gearbox 55 to overlap the first end 64 in a side view of the vehicle.

[0766] The straddle-type vehicle 1 includes a seat 3 and a storage box 25. The storage box 25 is disposed below the seat 3. The intake pipe 41 is disposed in front of the storage box 25. Therefore, the intake pipe 41 and the storage box 25 do not interfere with each other.

[0767] The fuel injection device 61 extends forward and upward from the intake pipe 41. The intake pipe 41 is disposed in front of the storage box 25. Therefore, the fuel injection device 61 is disposed in front of the storage box 25. Thus, the fuel injection device 61 and the storage box 25 do not interfere with each other.

[0768] The gear box 55 extends forward from the throttle valve 52. The throttle valve 52 is provided in the intake pipe 41. The intake pipe 41 is disposed in front of the storage box 25.
