The present invention relates to a motorcycle, and more specifically to the arrangements of a main harness and ABS pipes of a motorcycle.
As a conventional motorcycle, there are known a motorcycle in which a main harness for supplying electric power to multiple electrical components is arranged on the right side of a vehicle (see Patent Document 1, for example) and a motorcycle in which ABS pipes for an ABS (anti-lock braking system) are arranged on the right side of a vehicle (see Patent Document 2, for example).

Patent Document 2: JP-A-2007-008375
Since a conventional motorcycle is provided with a side stand on the left side of a vehicle, a vehicle body is tilted to the left side. Accordingly, the main harness is often passed through the right side of the vehicle body where water is less likely to be accumulated. Meanwhile, in a model of a certain vehicle type equipped with an ABS system, ABS pipes for brakes on front and rear wheels of the vehicle (in which a brake caliper for the rear wheel is provided on the right side) are arranged from the front to the rear of the vehicle. For this reason, when the main harness and the ABS pipes are arranged together on the right side of the vehicle as described in the above Patent Documents 1 and 2, flexibility of wiring design of the harness and the pipes is reduced, which may make it difficult not only to make packaging design of the motorcycle but also to perform operations for assembly and piping of the main harness and the ABS pipes, thereby lowering productivity of the motorcycle.
The present invention has been made in view of the foregoing circumstances and an object thereof is to provide a motorcycle in which a distinction between a main harness and ABS pipes can be easily made to enhance flexibility of packaging design of the motorcycle and to facilitate operations for assembly and piping, thereby improving productivity of the motorcycle.
In order to achieve the above object, the invention of claim 1 is characterized in that, in a motorcycle including: a main harness connected to a battery and arranged to extend in a front-to-back direction of a vehicle in order to supply electric power to a plurality of electrical components provided on the vehicle; an anti-lock braking system connected to brake calipers for a front wheel and a rear wheel and configured to adjust a brake hydraulic pressure depending on brake lock conditions of the front wheel and the rear wheel; and anti-lock braking system pipes configured to transmit the brake hydraulic pressure of the anti-lock braking system, the main harness is arranged on one side in a right-to-left direction of the vehicle and the anti-lock braking system pipes are arranged on the other side in the right-to-left direction of the vehicle.
In addition to the configuration of the invention of claim 1, the invention of claim 2 is characterized by further including a vehicle body frame including a right and left pair of frames, and in that the main harness and the anti-lock braking system pipes are arranged along the right and left pair of frames.
In addition to the configuration of the invention of claim 2, the invention of claim 3 is characterized in that the brake calipers for the front wheel and the rear wheel are provided on the vehicle while being offset to the right with respect to a vehicle body center line, and the battery is provided on the vehicle while being offset to the left with respect to the vehicle body center line, an anti-lock braking system modulator of the anti-lock braking system is provided on the vehicle while being offset to the right with respect to the vehicle body center line, and the main harness is provided on the left frame of the right and left pair of the frames and the anti-lock braking system pipes are provided on the right frame of the right and left pair of the frames.
In addition to the configuration of the invention of claim 3, the invention of claim 4 is characterized by further including engine electrical components including a heaterless oxygen sensor, an ignition coil, and a regulator, and in that at least one of the heaterless oxygen sensor, the ignition coil, and the regulator is arranged on the left side of the vehicle body center line.
In addition to the configuration of the invention of claim 4, the invention of claim 5 is characterized in that all of the heaterless oxygen sensor, the ignition coil, and the regulator are arranged on the left side of the vehicle body center line.
According to the motorcycle of claim 1, the distinction between the main harness and the ABS pipes can be easily made because the main harness is arranged on the one side in the right-to-left direction of the vehicle while the ABS pipes are arranged on the other side in the right-to-left direction of the vehicle. Thus, it is possible to enhance flexibility of packaging design of the motorcycle and to facilitate operations for assembly and piping of the main harness and the ABS pipes, thereby improving productivity of the motorcycle.
According to the motorcycle of claim 2, the main harness and the ABS pipes are arranged along the right and left pair of frames of the vehicle body frame. Hence the distinction between the main harness and the ABS pipes can be easily made by the right and left frames. Thus, it is possible to further facilitate the operations for assembly and piping of the main harness and the ABS pipes, thereby further improving productivity of the motorcycle.
According to the motorcycle of claim 3, the brake calipers for the front and rear wheels are provided on the vehicle while being offset to the right with respect to the vehicle body center line, and the battery is provided on the vehicle while being offset to the left with respect to the vehicle body center line. Meanwhile, the ABS modulator of the ABS system is provided on the vehicle while being offset to the right with respect to the vehicle body center line, the main harness is provided on the frame on the left side of the right and left pair of the frames, and the ABS pipes are provided on the frame on the right side of the right and left pair of the frames. Therefore, the main harness including multiple electrical wires and having no limitation of flexibility of design is arranged on the left side of the vehicle as in the case of the battery while the ABS pipes being made of metallic pipes and having a limitation of flexibility of design is arranged on the right side of the vehicle as in the case of the brake calipers for the front and rear wheels as well as the ABS modulator. Thus, lengths of the main harness and the ABS pipes can be minimized to suppress manufacturing costs of the motorcycle.
According to the motorcycle of claim 4, the engine electrical components including the heaterless O2 sensor, the ignition coil, and the regulator are provided on the vehicle. At least one of the heaterless O2 sensor, the ignition coil, and the regulator is arranged on the left side of the vehicle body centerline. Accordingly, at least one of the heaterless O2 sensor, the ignition coil, and the regulator is arranged on the same side as the main harness which is arranged on the left side of the vehicle. Thus, the length of the main harness can be minimized to suppress manufacturing costs of the motorcycle and to facilitate a wiring operation of the main harness.
According to the motorcycle of claim 5, all of the heaterless O2 sensor, the ignition coil, and the regulator are arranged on the left side of the vehicle body center line. Hence all of the heaterless O2 sensor, the ignition coil, and the regulator are arranged on the same side as the main harness which is arranged on the left side of the vehicle. Thus, the length of the main harness can be minimized to further suppress manufacturing costs of the motorcycle and to further facilitate the wiring operation of the main harness.

As described above, according to the motorcycle 10 of this embodiment, the main harness 50 is arranged on the left side of the vehicle while the ABS pipes 101, 102 and 106 are arranged on the right side of the vehicle. Hence a distinction can be easily made between the main harness 50 and the ABS pipes 101, 102 and 106. Thus, operations for assembly and piping of the main harness 50 as well as the ABS pipes 101, 102 and 106 can be facilitated to improve productivity of the motorcycle 10.
