Saddle riding vehicle

Abstract:

A saddle riding vehicle includes: a body frame; a fuel tank; an upright internal combustion engine; a fuel injection device; and a high-pressure fuel pump. The high-pressure fuel pump is configured to be driven by one of an intake-side camshaft and an exhaust-side camshaft. The high-pressure fuel pump is mounted on an upper surface of a cylinder head cover in an attitude inclined rearward toward the other of the camshafts. The high-pressure fuel pump can thus be protected from disturbances from the sides, and the length of a high-pressure pipe for feeding fuel from the high-pressure fuel pump to the fuel injection device can be shortened. The vehicle protects the high-pressure fuel pump from disturbances from the sides, and prevents acceleration of vaporization of fuel by reducing heat which the high-pressure fuel pump receives from the cylinder block.
