It's a great idea. Honda installed them on the fully-faired CBR1000F, ST1100, and Pacific Coast in the early 90's. My 1990 CBR in my avatar has a steel bar that sticks out from the downtube to the mainframe. A replaceable plastic strip hides the bar on the fairing. It divides the two radiator heat exhaust vents on the side. It's not even noticeable. By the way, the gray plastic puck sticking out from the end of the crank is also a replaceable skid plate. Just hope I never have to test them.
