Abstract: An air intake device for introducing air into an engine includes an intake duct, part of which is disposed in a space defined by a front wheel apron forming an inner wall of an engine compartment, and a front fender for forming an outer wall of a vehicle body. A hole is formed in the wheel apron for providing an opening through which an upstream portion of the intake duct passes so as to have its intake opening open into the engine compartment.

Abstract: An intake system includes an air inlet passage for introducing air into an air cleaner. The air inlet passage is formed by an outside passage, formed with an inlet opening at an upper portion thereof and extending downward from the inlet opening, an inside passage, extending upward to the air cleaner, and a generally U-shaped intermediate passage, extending between the outside and inside passages so as to form a space therebetween. A liquid container is formed integrally with a stationary resonator disposed close to the space. The resonator is connected, by a connecting passage, with the air inlet passage at the generally U-shaped intermediate passage.
