I've had those fangs on my 09 Heritage for 5 years and was quite happy how little buffeting there was. Last summer bought a nice light carbon fiber helmet and couldn't believe the head shake I got , with windshield, without, with face shield or without. I Decided not all helmets are created equally in the head buffeting department. Whoda thought, eh
I bought a set of fork wind deflectors, the angular ones with the notch cut out. Apparently there are 3 main styles, these , the angular ones without the notch and Harley's new ones, rounded and concaved. This style mounts on the outside of the rubber grommets with the top angle slanting forward and the side angles slanted to the rear. If you have a quick detach windshield and auxiliary lamps this is the only way they will fit. Quick 15 min install just loosen both mounting bolts and do one at a time. I like the look of the added chrome And they do work. I can actually read the signs on the freeway now. Reduce buffeting by at least 70%. Well worth it
HD fangs on my 14 heritage. After a few thousand beers, staring at em after putting them on and telling yourself over and over again "what did I just do" all went away after the first ride
