No. I can't. I've tried and want to, but the wind buffeting is just too much. I've ridden sportbikes for years and have worn my gear and I don't have issues with image and appropriate head gear (and that's saying alot since I'm a fatass and live in south Texas - I'm used to sweating my *** off when I ride.) And I've tried everything - lowers, those butterfly things on the side of the batwing, been through 3 or 4 different style of windshields. The buffeting (shaking my head around) is just too much. I've tamed it down with some of these things, but not elimenated it. I've done a couple of 4500 mile trips with my Harley half helmet wishing I could make my full face work for me.
i wear one on my ultra with the street glide sized windscreen and the buffeting is quite noticeable and somewhat noisey. with the regular ultra windscreen everything is fine.
