Hi Steve. I am 6 foot three, so I needed a taller windshield. I bought from Mark, at California Scientific. I had good luck with California scientific before, buying a taller windshield for my FJR; and this one, for my Ninja, was no exception. The windshield, including shipping, cost me $176, to my home in Southern California. National seems to have a similarly sized windshield as well, but I have no experience with their products.
