    Abstract: An internal combustion engine is mounted on the saddle-riding vehicle. The engine includes: a cylinder head; a cylinder head cover; a fuel injection valve whose distal end is directed to a combustion chamber; a cam shaft; a fuel pump which feeds fuel due to an action of a cam which integrally rotates with the cam shaft; a fuel pump mounting member which is fixed to the cylinder head and on which the fuel pump is mounted; and a downstream side fuel pipe which feeds fuel from the fuel pump to the fuel injection valve and has flexibility. The above arrangement improves maintenance property by making a routing space of the fuel pipe compact by shortening the length of the fuel pipe while enhancing protection of the sides of the vehicle including the fuel pump.
