Abstract

A straddle-type vehicle, for example a motorcycle, having an in-cylinder injection injector directly injecting a fuel into a combustion chamber has compact dimensions and good fuel injection. A low pressure pump carries fuel from a fuel tank, and a high pressure pump 123 pressurizes the fuel from the low pressure pump. The high pressure pump 123 is connected with each in-cylinder injection injector through a delivery pipe. The low pressure pump is connected with each in-pipe injection injector through the delivery pipe 118. The high pressure pump 123 is fixed to a cylinder head cover 50. At least one part of the high pressure pump 123 is disposed between left and right main frames 13. A high pressure fuel piping 127 is connected to the delivery pipe while passing above a right end part of the cylinder head cover 50 from the high pressure pump 123.
