After MONTHS of trying to get the new Wunderlich one peace windscreen, I received the windscreen yesterday from bmwscruz.com. All I wanted was reduced buffeting of my helmet, and I got a lot more. The buffeting for me (6'1", 32" inseam, high sit position) is reduce to about half. I was hoping for a 70-80% reduction (a guy can dream can't he?) of the buffeting. The reduced air pressure on the chest and arms (gorilla arm!) is huge. I feel like I'm behind an RT or something. I had forgotten how much energy is spent fitting the wind on an fairing less bike. Now, I can clearly hear the stock exhaust note, and you can't mistake that asthmatic vacuum cleaner / rattling tin can sound of GS's exhaust note.
Great windscreen... Highly recommended.
