Thanks for the quick replies. The reason I asked was that when I asked Blair from Madstad what this dimension was on the 24" windscreen, he said it was 16". The dimension you both gave me tells me that his dimension of 16" cannot be correct. The GIVI windscreen that is on my bike was originally 22" but the previous owner cut off 2". The dimension from the top screw to the top is now 10". I want one that is around 13-14". He was going to double check his dimension and get back with me. I am 6'2" with a inseam of 34" and have a Russell seat in the high position. Again, thanks for your help.
