A control device of a leaning vehicle for controlling bright lighting and dim lighting for a plurality of oblique areas. When the leaning vehicle is upright, the control device controls the lighting by designating one or more of the plurality of oblique areas as in a brightly lit area to which adaptive lighting control is applied, and by designating the other oblique areas as in a dim area. The dim area includes an uppermost oblique area. When the leaning vehicle turns left or right, as a lean angle in a direction of the turn increases, the control device controls the lighting by designating a second uppermost oblique area that is located immediately below the uppermost oblique area in the up-down direction as in the brightly lit area, and moving the uppermost oblique area from the dim area to the brightly lit area.

A saddle-riding type motor vehicle comprises steerable and rollable front wheels, a drive rolling wheel, an articulated rolling quadrilateral connected to a frame, and a steering assembly pivotably connected to the frame to control the front wheels. A suspension assembly is interposed between the front wheels and the quadrilateral to allow a sussultatory movement of the wheels with respect to the quadrilateral. The latter comprises lower and upper cross-members hinged to the frame to oscillate about rolling median axes parallel and substantially lying on a center plane of the motor vehicle. The articulated rolling quadrilateral further comprises first and second uprights hinged to the cross-members to rotate about further rolling axes parallel to the median rolling axes. A front-end fairing is directly and rigidly connected to one of the cross-members of the articulated roll quadrilateral, and comprises two wheel arch portions arranged above the front wheels.

A headlight device includes a headlight and a control device. The headlight includes a plurality of light sources configured to light a single left oblique area located in the ahead-driving direction of the leaning vehicle on the left, a single right oblique area located in the ahead-driving direction of the leaning vehicle on the right, and one or more lower areas located in the ahead-driving direction of the leaning vehicle. The control device controls the headlight to light the left and/or right oblique area based on adaptive lighting control. The left and/or right oblique area lit based on the adaptive lighting control spread more outwardly in a left-right direction than any of the lower areas. Uppermost points of the left and right oblique areas are positioned further leftward and rightward than leftmost and rightward points of each of the one or more lower areas, respectively.
