An ECU is covered by a fuel tank and an upper cover which are vehicle body trim parts along with the upper surface of an air cleaner box. A frame holding duct is connected to the air cleaner box, the frame holding duct extends vehicle forward from the air cleaner box, is connected to a body frame, and is arranged inside an upper cowl, the upper cowl covering the front portion of the body frame, a branching portion of the intake air is arranged in the frame holding duct, and a branching passage extending from the branching portion is disposed between the upper surface of the air cleaner box and the fuel tank and the upper cover and is positioned in front of the ECU.

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 including a body frame having a head pipe, a front cover in front of the head pipe, an exterior cover laterally covering the body frame, a fuel tank disposed behind the head pipe, an air cleaner disposed directly below the fuel tank, a duct disposed between the front cover and the head pipe and extending from an opening in the front cover, and a wind guide cover disposed between the head pipe and the fuel tank. The fuel tank and the exterior cover forms a wind guide pathway therebetween, the wind guide pathway being directly below the fuel tank, and being laterally covered with the exterior cover. The wind guide cover is configured to lead traveling wind passing through the duct from the opening to the wind guide pathway, so that the wind guide pathway leads the traveling wind to an air intake port of the air cleaner.

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.

A straddled vehicle including a body frame having a head pipe, a front cover disposed in front of the head pipe and having an opening at a middle of the straddled vehicle in a width direction, a duct disposed in front of the head pipe and extending rearward from the opening to form a traveling wind pathway for traveling wind flowing from ahead and taken in through the opening, a headlight of a single light configuration, which overlaps the head pipe in a front view of the straddled vehicle, and is disposed inside the duct at the middle of the straddled vehicle in the width direction and further rearward than the opening, and an aero-stabilizing member disposed inside the duct and laterally covering the headlight, the aero-stabilizing member being configured to direct the traveling wind flowing from ahead to flow away from the head pipe in the width direction.

An air intake structure of a saddle riding vehicle is disposed in the saddle riding vehicle in which a frame including a left and right pair of main frames and an air box are disposed, an intake passage is disposed between the main frames and an outer periphery of the head tube, and the intake passage includes: a front side intake duct that extends forward; and a rear side intake duct that couples the air box to the head tube. In the air intake structure of the saddle riding vehicle, the rear side intake duct is a separate body from the air box, the air box has a front surface on which an opening inserted through the rear side intake duct is provided, and the rear side intake duct is coupled to an intake passage from an inside of the air box through the opening.

A two-wheeled vehicle includes a frame, a plurality of ground-engaging members for supporting the frame, and an engine supported by the frame and operably coupled to the ground-engaging members. Additionally, the two-wheel vehicle includes a down tube extending downwardly from a front end of the frame. A front fairing is supported on the down tube.

An assembly for a snowmobile includes an airbox having a plenum for coupling to a throttle body of an engine and two branches defining openings for air intake. A storage box is mounted between the two branches and defines area for receiving a console. The airbox is part of a hood of the vehicle and includes an opening over a storage box. The disclosure also includes a ribbed bumper mount with a latch assembly for securing the hood.

A saddle riding vehicle includes a body frame, an exhaust pipe, a muffler, and a catalyst. The body frame includes a main frame, a seat frame that extends rearward from the main frame and supports a seat for occupant, and a rear frame that extends from the main frame upward to a rear and is connected to the seat frame. The exhaust pipe extends rearward of the vehicle from an exhaust port of an engine. The muffler is connected to a rear end portion of the exhaust pipe. The catalyst is disposed in the muffler. An air cleaner box is disposed rearward of the engine. The catalyst disposed in the muffler is disposed in a space surrounded by the main frame, the seat frame, and the rear frame and overlaps with the air cleaner box as viewed in a side view of the vehicle.
