Installed medium windshield per my height 5' 9'' Ride to BBQ 170 miles hot and sunny, shield worked better then stock, buffeting or lack of was controllable with just a little up or down and the wind through the hole was dissipated before it came past the dash.
The trip back 100 miles of RAIN WOW love the fact that the rain drop's were only on one side, my stock shield would get wet on both sides, add two sides of my helmet shield I was trying to look through four rain drops. now I can see, even road for a while with no eye protection. as to the rain coming through the hole it went somewhere as by magic.
I made as manny mistake as I coulld so the critic will have something to do.....what do u want I only have one finger....
