Abstract: A fuel tank includes a tank panel in which a storage space of a fuel is formed, a tank inlet fixed to the tank panel, and a tank cap that allows the tank inlet to be opened and closed. The tank inlet includes a bottomed cylindrical inlet plate to which the tank cap is attached, an inlet pipe that protrudes from a bottom wall of the inlet plate into the storage space, and a separator configured to separate the fuel entering from the storage space into a liquid component and a gas component. The separator is supported by the bottom wall of the inlet plate in the storage space, and the separator is disposed on an outer side of the inlet pipe and on an inner side relative to an outer edge of the inlet plate in a bottom view of the tank inlet.

Abstract: A fuel tank includes an outer component including an outer panel forming a tank outer shell and an inlet plate formed separately from the outer panel, an inner component including an inner panel forming a tank inner shell and an inner connection plate formed separately from the inner panel, and a pipe passing through inside of the outer panel and the inner panel and connecting the inlet plate and the inner connection plate. The inlet plate is joined to the outer panel, the inner connection plate is joined to the inner panel, and the inner panel is joined to the outer panel.

Abstract: A fuel pump unit is mounted on a predetermined position in a fuel tank. There are a supporting mechanism to support the fuel pump unit at the mounting position and a holding mechanism to fixing and holding the fuel pump unit supported at the mounting position, and an opening portion through which the fuel pump unit is inserted into the fuel tank is closed by a cover member being a separate body from the supporting mechanism and the holding mechanism.

Abstract: A fuel tank unit of a motorcycle comprises a tank body having a bottom portion to which a through hole is formed in a standing state of the motorcycle, a fuel pump mounted to the bottom portion of the tank body, a pump case having a bottomed bawl-shape mounted to be liquid-tightly to the through hole formed to the tank body so as to communicate an inner space of the pump case with an inner space of the tank body through the through hole, and a suction unit for the fuel pump disposed in the pump case at a height level between the bottom portion of the tank body and a bottom surface of the pump case. A pump mount bracket is further mounted to the bottom portion of the tank body to be liquid-tightly and formed with a pump mount hole to which the fuel pump is mounted.

Abstract: A fuel tank system of a motor bicycle according to the present invention comprises: a tank main body made of a synthetic resin, which is formed into a reverse U-letter shape in its longitudinal section in a manner of riding on a front head portion of a vehicle-body frame; a fuel supply port which is provided on an upper portion of the tank main body; a receiving pan portion which is provided in the fuel supply port; a relay joint which is arranged in a vicinity of a bottom portion of the tank main body and whose attaching direction is the substantially same as an attaching direction of the receiving pan portion; and a drain pipe which comprises a soft hose, passes through an interior of the tank main body, and connects between the receiving pan portion and the relay joint.

Abstract: A motorcycle is provided with a body height adjustor capable of adjusting the body height of the motorcycle by changing lengths of front suspensions and a rear cushion unit. The body height adjustor includes a first hydraulic jack for extending and retracting the front suspensions, a second hydraulic jack for extending and retracting the rear cushion unit and a body height adjusting unit to transmit hydraulic pressure of hydraulic fluid in the rear cushion unit to the first and second hydraulic jacks through hydraulic hoses. The rear cushion unit is provided with a rear oil damper and a coil spring against which the second hydraulic jack abuts and the initial load of the coil spring is changed by the hydraulic pressure in the rear cushion unit. The second hydraulic jack is movable in a direction towards the coil spring with respect to the rear oil damper to change the initial load of the spring.

Abstract: A motorcycle having a body height adjustor in which a body height adjusting unit transmits the hydraulic pressure of a pressurized fluid within the rear cushion unit simultaneously to hydraulic jacks of the rear cushion unit and the front suspension units so as to change the length of the front suspensions and the rear cushion unit and to thereby adjust the body height of the motorcycle, is disclosed. The body height adjusting unit is disposed upon the side of the body frame remote from the exhaust pipe. A hose connector for connecting the body height adjusting unit and the hydraulic jacks of the front suspensions is disposed at the rear of the front suspensions and in front of the body height adjusting unit. The hydraulic hoses are disposed along a line corresponding to the center of the front fork of the motorcycle as considered in the widthwise direction of the motorcycle.
