I installed a 6.5 on my 18 sgs and it works very well kicking the air up over your head. I bought the tinted windscreen. I can see over it just fine during the day. But at night is a different story if you have alot of potholes where you live. I live in the Chicago area and night riding local city streets that are not lit well sucks. Cant really see the size of potholes until you are right up on them do to the height of the windshield. I'm 5' 10" and I just bent both my wheels and broke my rear legend revo a's on a nasty pothole last week due to not being able to see the size or depth of the whole. So my suggestion is to test one out day and night riding to see how you like it. Just a suggestion and my experience with it so far.
