Abstract

A motorcycle, such as a scooter-type motorcycle, includes an engine main body. The engine main body is non-swingably supported by a frame at a location under a seat. A transmission case is swingably supported by the engine main body. A rear wheel is attached to the transmission case and hence swingable relative to the frame. A fuel system is provided atop the engine main body, and hence is not swingably relative to the frame. The engine main body has cylinder bores which are spaced across the width of the motorcycle. The cylinder bores are tilted upwardly and forwardly, so as to create a space below a forward portion of the engine main body. A fuel tank has a rear portion disposed below the forward portion of the engine main body.
