ABSTRACT:
An air intake structure for a motorcycle includes a pair of hollow laterally spaced frames extending from a headpipe to a rear portion of the motorcycle, a hollow cross member connecting the frames together at an intermediate portion thereof, wherein the hollow interior of the cross member communicates with the hollow interiors of the frames. Intake openings are provided at a front portion of the frames for feeding air into the frames, while an exhaust opening is formed on the bottom of the cross member for exhausting air downward to the engine air intakes. A fuel tank cover is provided to cover a flexible fuel tank disposed between the laterally spaced hollow frames. The fuel tank cover includes a hollow fairing stay formed integrally therewith for supporting a motorcycle fairing, wherein the hollow fairing stay forms an air duct for directing air from an air inlet in the fairing to the intake openings of the frame.
