I tested it today 10-28-12
Believe it or not we made it to 60* today. All the snow is melted and there is sand in the intersections so I headed out for a ride on the Interstate. The bike loves the cool air so off I went running through the gears wearing my 3/4 helmet. Jamming down the Interstate at 75+ my helmet made no noise from any buffeting effect so I lifted the shield up completely and had no issues. I ran it up to 85+ and still no ill effects. Then I retracted my built in sun shade and there was no problem with air in the eyes. When I got within a mile of home I stopped at one of the interchanges removed my helmet, no hat or skull cap, slammed it in gear and off I went all the way to 80. All I got was nice clean air on top of my head, nothing in my face nor my eyes. I had no issues seeing over the shield and I was glad I got a light tint. I had to stick my head way out to the side to get any forceful air. I think a passenger will be happy with it.
I like it and its going to be a keeper.
