The Givi Airflow windshield I ordered last week arrived and I couldn't wait to install it tonight. It was fairly simple, I checked the instructions mainly to figure out which pieces were meant to go on in which order and it worked out fine.
When I had it installed it was too dark to take photos but I definitely wanted a test ride and went out on Highways 85 and 280 to try how it works. I stopped several times to adjust the height and overall I'm very impressed. I was up to pretty high speeds that I won't admit here and was surprised that I still had no problems keeping the visor open even at speeds I normally don't ride.
When going my typical 60 to 70 cruising speed I had the visor up all the way, no earplugs in and it was no problem at all. With the upper part of the windshield in the low position I got a little bit of wind in the face but not much, with it being halfway up or higher there was virtually no wind other than a little bit of turbulence sometimes. Nothing to worry about at all.
So far so good. I like it and I think it's a great value, especially together with the Adventure Winglets I installed a while ago. I wish I had that windshield last weekend for my trip to Lake Tahoe. Would have been a lot easier on the way back in the East Bay.
One thing: I would like to angle the windshield back a little bit more for even less turbulence and to get the distance between windshield and helmet a bit smaller but that doesn't seem to work given the way the BMW hardware works. I'll have to take a closer look again whether I missed something when assembling it again, but I think I got it right and there is not much more I can do there other than putting thick spacers under the front screws.
I'll report back when I find out more and I'll add pictures as soon as I can take them in daylight.
Oh, and one more thing: the upper part that can be moved catches quite a lot of glare from the headlights. In the dark it's pretty annoying, no problem when in city traffic but in dark rural environments this will be very distracting. I'll probably add something on top of the head lights to avoid the glare. I had that effect with the stock windshield, too, it just wasn't so pronounced.
