A saddled vehicle includes an air cleaner and a vehicle body movement sensor. The air cleaner takes travel wind in an air cleaner box to purify air of the travel wind and supplies the purified air to an internal combustion engine. The vehicle body movement sensor is received in a recess and measures movement of a vehicle body. The recess is defined by a flat surface that crosses a rear wall of the air cleaner box. This provides a saddled vehicle including a vehicle body movement sensor that is disposed without reducing the volume of an air cleaner box.

A vehicle includes a plurality of ground-engaging members and a frame supported by the ground-engaging members. The frame includes a front frame member and a rear frame member coupled to the front frame member. The vehicle also includes a powertrain assembly supported by the frame and an air intake assembly operably coupled to the powertrain assembly and the front frame member. The air intake assembly includes at least one air inlet member extending into a portion of the front frame member. The air inlet member extends from an inlet opening to an outlet opening, and a portion of the air inlet member intermediate the inlet and outlet openings has a diameter less than a diameter of the outlet opening.

A side cover structure includes a main frame extending rearward from a head pipe, a seat rail positioned behind the main frame, a side cover fixed to the seat rail from an inner side in a vehicle width direction. Below a driver seating surface of a seat on the seat rail, the side cover is exposed, to an outer side in the vehicle width direction, from an opening formed by rail members included in the seat rail.

In an air cleaner for a vehicle, a connection part of a first intake duct to a cleaner case is disposed in a front half portion of one of left and right half portions of the cleaner case, the first intake duct including a first air inlet port opening forward. A connection part of a second intake duct to the cleaner case is disposed in a rear half portion of an other of the left and right half portions, the second intake duct including a second air inlet port opening rearward. The first intake duct is formed to include a first air outlet port opening rearward inside an unpurified chamber and curve in an up-down direction in a side view, and the second intake duct is formed to include a second air outlet port opening forward inside the unpurified chamber and curve in a right-left direction in a plan view.

An air suction device for a vehicle equipped with an internal combustion engine. The air suction device includes a device guiding purified suction air for combustion in the direction of the internal combustion engine, and an air filter element and a housing receiving the air filter element, and at least one air guiding device. The air guiding device is formed in the shape of a channel and is provided for guiding suction air to the housing. The air guiding device extends in the region between a holding device and the housing. The holding device is formed to receive at least one light source and has an air leading channel adjacent to the light source, which is connected in an air guiding manner to the air guiding device.

A straddled vehicle having a body frame including a head pipe, a front cover disposed in front of the head pipe, a duct disposed in front of the head pipe and extending rearward from an opening in the front cover, to thereby form a traveling wind pathway for traveling wind taken in through the opening, and an aero-stabilizing member. The aero-stabilizing member includes a middle portion disposed below a lower distal end of the front cover, directly below the opening in a front view, a lateral portion extending from the middle portion to a more outer side than the opening in a width direction, apart from the front cover with a gap therebetween in an up-and-down direction, and a front edge slanted forward and downward from the middle portion and the lateral portion, the front edge being partially disposed further forward than a lower front end of the duct.

Intake efficiency in an intake system is improved. An intake system takes air through an air inlet duct extending from an air cleaner case, and includes a vortex generator that causes the flow of the intake air inside the air inlet duct to rotate around an axis of the air inlet duct.
