I use a 6" over windshield in the winter. . . . . it's gayness depends on the angle you look at the bike.
However, it keeps the mist off me face, and a little warmer. If that makes me gay, then rename me Za Za, and ship me off to La Cage Aux Folles.
In the summer, generally I run no shield at all because of the buffeting from the stock height shield.
All joking aside, I have seen, once in my life, a very short backrest/luggage rack on a turbo.
The rack was designed to hold a battery in the event of a stator failure.
Nowhere near as ugly as the one pictured.
