The answer is different mirrors. The good news is, as these things go, they're not too expensive...
Split Vision Fairing Mount Mirrors
See even more of the world that you just passed. This exclusive design Split Vision Mirrors minimizes blind spots and provides a wide panoramic rear view of the left and right lane, and the road behind you. The mirror features a large primary panel for normal view, and a second outboard convex panel for a wider field of vision. Slightly larger than the standard-view Fairing Mount Mirrors, these split vision mirrors offer the same full range of adjustability. A direct bolt-on replacement for standard-view Fairing Mount Mirrors, the kit also includes the hardware and mounting template required for easy and accurate installation on other models.
