2019 CVO Road Glide. I have tried the Klockwerks 9" sport flare, a great looking windshield but it did not work for me due to too much buffeting around the top of my helmet, I tried the 14" sport flare, again too much buffeting plus a lot of optical distortion. I have just now tried the freedom shield 14" and have the same issue, in all cases the buffeting was bad enough to be too uncomfortable. Now I am not sure what to try next, I have come to the conclusion that the reverse curve at the top of these windshields does not work as advertised, it merely creates unstable eddy currents of air. I had the same issue with a windvest shield on another bike but being handlebar mounted, I could rotate it back until the buffeting went away but the downside was more wind blast on my upper torso. I have talked to others who have the freedom shield and it seems to work well for them, not sure why it's a problem for me.
Hey neighbor, just wondering what is happening with your specific aerodynamics. I have used and am currently using a Freedom Shield windshield on my 18 RG with great success. I can even ride with my regular eye glasses with no wind issues.
If you are using the proper size (windshield coming up to the bottom of your nose) it should be working as designed. When at highway speeds you should be able to take your ungloved hand and slowly run it up along side your helmet until you feel strong wind coming over your shield, which with the proper size shield, should be right at the top of your helmet. If your windshield passes that test try opening the 3 vents in your fairing to reduce buffeting. This time of year I close the bottom left one and leave the other 2 open, unless caught in the rain then I close all 3. Are you wearing a modular helmet with the front open and sitting above your helmet? If all the above is fitted properly you should be good.
Of coarse there is always the BSR factor that most of us deal with for shocks, seats, windshields and even stereos to be considered.
Good luck!
