A vehicle, such as a motorcycle, includes an air intake assembly having a fixed funnel for introducing air to an intake port of an engine, and a movable funnel that selectively cooperates with the fixed funnel to introduce air to the intake port. The vehicle also includes a rotary shaft and a parallel linkage located on a first side of the movable funnel for movably supporting the movable funnel, and a drive source, such as a motor, located on a second side of the movable funnel generally opposite the first side for driving the parallel linkage. In one arrangement, the rotary shaft and parallel linkage are located on a forward side of the movable funnel and the drive source is located on the rearward side of the movable funnel.
