An air cleaner for use in combination with a fuel system of an engine, includes an air cleaning element housed within a casing. Air introduced from an air inlet, defined in the casing, follows an air flow path from the air inlet passing through the air cleaning element. The air flow path includes a direction change of approximately ninety degrees. This direction change transpires over a curved guide surface formed in the casing to reduce the likelihood of vortexes which reduce the air ram pressure. The curved guide surface may include a detachable panel. Also, the panel may include an air path to an air branch chamber. When two air inlets are used, it is advantageous to include a partitioning wall separating the two air flow paths prior to the air cleaning element.

Wing portions are used to reinforce ground pressure of a front wheel of a vehicle, such as a motorcycle, in which a center of gravity of the vehicle in a driver riding state is positioned between a front wheel and a rear wheel of the vehicle. The wing portions, each of which is provided in such a manner that an aerodynamic center thereof is positioned forward and downward from the center of gravity of the vehicle, produces down-lift.

A pair of air inlet openings and a pair of air introduction paths are formed in a leftwardly and rightwardly symmetrical relationship on left and right side portions of a windshield. The air introduction paths are each formed as a smooth continuous curved face in a transverse direction, and a body center side curved face of the air introduction path is formed more moderate relative to an outer side curved face. When surface air flows along the surface of the front face flow on the air introduction paths since the body center side curved faces are moderate, exfoliation occurs less likely, and the external air admission efficiency of the air inlet openings is raised.

A cowling assembly is mounted on a front portion of the frame of a motorcycle. The cowling assembly includes a cowling covering a front portion of the frame, a windshield disposed on and continuously blending into a central upper portion of the cowling, and a pair of air ducts extending along laterally opposite sides of the windshield and having an air inlet for introducing an air flow developed when the motorcycle is running into the cowling and an air outlet for discharging the air flow introduced from the air inlet in a substantially upward direction. The air inlet is positioned near a lower end of the windshield on each side of the cowling, and the air outlet is positioned at an upper end of the cowling.

A rearview mirror device for a motorcycle is designed to reduce the area of forward projection of the motorcycle and increase the rigidity of the support member for a rearview mirror. The rearview mirror device includes a motorcycle frame, a steering handlebar projecting laterally from the motorcycle frame, a pair of handgrips mounted on opposite outer ends, respectively, of the handlebar, and a pair of rearview mirrors disposed forwardly and downwardly of the handgrips, respectively, when the handlebar is in a neutral steering position.
