When I tested the Street Glide I was whereing a open faced helmet with a pull down shield. On my C50 with a windshield I had awfull buffeting with my half helmet. Espessially with the visor on. I put on lowers and it went away. I now can ride at 80 with no issues what ever. This time of year like today for instance I rode to work with my open faced with my shield down and no issues even at 80 mph. The lowers make a HUGE difference. If you have buffiting get lowers...
