I made the windshield from $24.00 worth of plexiglass and salvaged metal. (Next time I'll use Lexan....less problems with cracking when cutting. It doesn't seem to slow the bike at all, and helps alot with the comfort now that winter is coming.
It measures 30 in. tall and 36 in. wide It seems huge to me too, but I can look at the road over the top easily, and my hands don't get the windchill effect. I don't have very good pics right now but will try to get them soon.
