My third spring with my 900 classic and I put a windshielf on. I was really nervous about it being 6'3". I test rode a stock one before I bought my bike and buffeting was beyond awful. This one is perfect and I still have to drop it down a half inch as it's a hair to tall for me. With out the lowers I had no air coming over the tank, the air was coming over my knees. I put a hand over my knee while riding and it stopped it. I'm think maybe my tool bag stops the air from coming up over the tank.
