Design seems to have become the art of taking something that functions perfectly well and looks fine then replacing it with something that doesn't work as well and looks fucking dreadful. This is true in so many areas, not just motobikes and cars but domestic appliances, bathroom and kitchen fittings and even electrical outlets and light fittings - bane of my life!
