I've got the Givi installed on my bike. I'm 6' 3" but my inseam is only 31 inches....so most of my height is in my torso. I'd probably be about 6' 8" if my legs were proportionate with my torso
At any rate, the Givi is about 5 inches taller than the stock wind screen. It lowers the wind noise enough for me to use the blue tooth in my helmet, and it deflects most of the bugs up over my helmet....but there is still quite a bit of air....which if it's 105 F might not be a bad thing. I still look way over the top of the thing. I could probably use about 3 inches more....errr windscreen that is. But it ain't bad now.
