A vehicle has a body frame that does not interfere with an injector. A down tube extends downward to the rear. An engine is disposed with its cylinder axis inclined rearward. An intake pipe located between the down tube and the engine extends obliquely upward from a forward side of the engine. A fuel injector is attached to the intake pipe. The intake pipe includes a straight throttle body connected to the engine. The fuel injector is mounted on a rearward side of the throttle body relative to a forward side where the down tube is disposed.
