A motorcycle fairing includes a fairing body having a mounting surface for mounting an audio speaker. The fairing body defines an internal space for accommodating a portion of the speaker. The fairing includes an external wall portion. An internal wall is configured, along with the external wall portion, to seal the internal space. An upper portion defines an inboard portion and an outboard portion. An upper surface of the inboard portion is positioned below an upper surface of the outboard portion. An edge is defined by the upper surface of the outboard portion. The upper surface slopes downward on each side of the edge. The edge extends in an inboard-to-outboard direction in a forward-to-rearward direction. In some configurations, the inboard portion defines an airfoil shape.
