August 3, 2005
The motorcycle according to the invention includes a main frame 20b that curves downward, an engine 1 and an air cleaner 26 positionedbelow the main frame 20b and an intake pipe provided below the main frame 20b, between the engine 1 and air cleaner 26. The engine 1 is mounted with an injector 11 for ejecting a fuel and includes a cylinder head provided with an injector mounting section that positions an injection nozzle 11a in a position between an axis of an intake valve 7 and a center axis of an intake port 3g and close to an end of the intake port 3g on the intake valve side. The intake pipe and injector are positioned so as to be prevented from interfering with each other. This avoids the injector and main frame from interfering with each other and prevents the placement flexibility of the engine from being lost. Furthermore, it is possible to provide excellent intake efficiency and improve the output of the engine.
