A motorcycle comprising an engine disposed below a main frame extending upward from a head pipe and suspended from a body frame having the main frame, and an air cleaner and a carburetor disposed above the engine, wherein a fuel cock operating with the negative intake pressure of the engine is provided on a fuel supply line coupling the carburetor and a fuel tank disposed below a passenger seat supported at the rear part of the body fame. The fuel cock 90 provided on the fuel supply line 88 extending downward from the fuel tank and coupled with the carburetor 38 is fixed to an intake pipe 39 connecting the carburetor 38 with the engine E. A negative pressure take-out pipe between an intake system and the fuel cock is thereby shortened and the number of parts can be decreased by eliminating the need for a part dedicated to venting of air from the fuel supply line. |
