The 19" suits me just fine I am 5'8 and the top of the winshield is even with my eyes. so if it rains i can still sit up a little bit to see were i am going. Installed on a 09' Vulcan 900 classic. Bought the trigger lock mount and love it. The directions on the mount are pretty bad, but I was able to mount it within about 45 min. Winshield is strong and really cuts the wind down. the only drawback is price, This is my first motorcycle experience and it seems that every part or accesory is just to expensive for what you get.
a little tip here i have a 2008 vulcan custom i purchased the fats 19'' with 9'' cutout they require the 9'' cutout for vulcan900 custom i did not go and get fitted for this windshield i took a chance with the height and width and it is perfect its hard to decide which one to get so if your riding a 900 custom this is the one. is excellent in every way !!!!!!!! thanks kirk for another excellent product
