I just heard today from Twisted Throttle that it would be "another two weeks" before the Givi 2010 V windscreen arrives in the U.S. Meantime, today, the CalSci 2010 V windscreen arrived. Looks good. The medium CalSci shield is about 1.5" longer/taller than the 09 V MikeShield GT windscreen. Looks good. They sent it all nicely wrapped, with cleaning fluid and a nice soft towel. Also sent along a nice tire pressure guage.
It's a nice heavy shield (about .008" thicker than the MikeShield GT). They made attaching brackets out of the clear, heavy windscreen plastic. The screen itself looks like a standard, pre-2010 windshield. A nice simple approach. With the brackets, should be able to mount other, readily available windshields. I'll try it this weekend.
