I appear to have the BMW tall version on the bike. I still get wind buffeting, especially when I turn my head to the side. I have looked at the aftermarket options and have not found any that measure longer, (17.75 inch) or so. Has anyone reduced wind pressure and noise with aftermarket due to superior engineering of the windshield. Over on Pelican parts forum one poster claimed a shorter shield worked best as the focal point was lowered to his chest. Confusing subject.
