Straddle vehicle

摘要

In a straddle vehicle such as a motorcycle, a harness in an electric power supply system which is thick, has a great weight, and is not easily mounted can be reduced in length as much as possible so that a weight and cost can be reduced, and assembling work can be made easier. An air cleaner and a fuel tank are disposed at a relatively rearward position such that the air cleaner and the fuel tank are disposed behind and distant from the head pipe to provide an electric component mounting space between the air cleaner and the fuel tank, and the head pipe, and a regulator, a relay box and a fuse box are disposed in the electric component mounting space. The fuel tank is disposed at a relatively rearward position such that its rear end portion is positioned behind and below a rear end of a main frame.

主权项

1. A straddle vehicle in which an ignition switch is disposed in the vicinity of a head pipe of a vehicle body frame, comprising:
a fuel tank disposed behind and distant from the head pipe; an air cleaner disposed behind and distant from the head pipe; an electric component mounting space which is provided between the head pipe, and the fuel tank and the air cleaner which are behind the head pipe, and in which electric components in an electric power supply system, including a relay box of ignition, a regulator, and a fuse box, are disposed; a heat radiation plate attached to a case of the regulator, the heat radiation plate being disposed below a lower end of the head pipe to directly receive ram air from forward; and a coupler of a harness connected to the case, the coupler being disposed behind a bracket fastened to the vehicle body frame not to directly receive the ram air.
