At least Dave_J put in a question mark. It's a lot longer than Trail Boss.
I'm guessing that Trail Boss was researching windshields, found an interesting thread, posted to it, then changed his mind and deleted the post, resulting in a blank post.
While we're here, I'm 6" tall and molded a piece of polycarbonate to match the curve of the windshield, then set it on small spacers to leave a slot while raising the top of the windshield about 3 inches. It lifts the turbulence to about the top of my helmet, makes the cockpit much quieter, and doesn't have the back push or windage effect that a taller screen usually causes. I'm very happy with it.
