The Hoppe Fairing has a 15", 12" and I beleive a 9" option on the shield, I'm 6'4" and I got the 12" and 15" to be sure. The 12" works fine and the 15" I like even better it is tall enough I have to look through it.
But that's my OP!
I'll let you know this weekend I should have it installed saturday morning. I bought the 15" thinking I could always cut it down. I will probably just buy a shorter one and keep the tall one for colder weather riding. I'm a little shorter than moose at 6'2".
