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. A blow valve incorporated within the body height adjusting unit is opened by means of the operation of turning OFF the ignition switch so as to forcibly set the motorcycle body to the lower level or height position. The position of a body height changeover valve incorporated within the body height adjusting unit is detected so as to indicate the body height of the motorcycle by means of a body height position indicator, or a transparent window formed within the casing of the hydraulic jack of the rear cushion unit so as to enable the rider to confirm the body height of the motorcycle.
