I ordered a large CalSci for my 2012 C14 Monday at lunchtime, it was shipped that very afternoon, and it arrived at my doorstep Friday at lunchtime. The windshield was packaged very nicely. So first off, CalSci gets my top rating for order processing.
The install was a breeze; it probably took less than 5 minutes.
I'm about 5'8" with a 30-32 inch inseam. With the windshield fully down, it seemed about the same height at the stock windshield fully up, with my line of sight several inches above the top of the screen. With it fully up, my line of sight is through the top couple of inches of the screen. This is exactly how I wanted it. I like to be able to have it well below my line of sight or be able to raise it above my line of sight.
The stock windshield was pretty much awful for me. Lots of turbulence and noise no matter what position I had it in, and it was pretty much unbearable at the 80-90 mph speeds at which I like to cruise. That's with my RF1100, but I also tried my wife's Scorpion Exo700 and it was the same. An hour at speed was about all I could take.
Now, with the CalSci fully down, I'd estimate I get about 70% less turbulence and about 50% less noise at any speed. With it fully up, there's almost no turbulence and very little noise at speeds up to 90 (haven't had a chance to get in the triple digits yet). I also have to get my wife on the back and have her tell what it's like back there. I'll update this when I get a chance to do that.
In summary, I'm extremely pleased with this shield. Top notch quality and highly effective.
PS: Whether you're in the market for a new shield or not, you really should check out the CalSci site. It has tons of great info related to motorcycles and motorcycling.
