I picked up one of these today (Touring size Puig). It said it was made for the Agility model. I got it at Cycle Barn in Lynnwood, WA. The price tag on it was $110, but I got it for $95 + tax. It had been in their inventory a while, and I was happy to help them out.
I heard that optimally, you want the top of the screen to be eye-level when you are sitting in your normal riding position. For me that would be about 16 inches above the dash. However, although the Windscreen is about 16 inches high, I'll be mounting it about 6 inches lower than the dash (and about a half an inch from the "cowl") so that a.) the lower flares of it line up with the handlebar grips, and b. so that it will not vibrate at speed.
If I can figure out how to do it, I may also try to mount it flush against the "cowl", but if I do that, I will need to add a rubber bumper along the bottom of the windscreen. And since the cowl is curved, the bumper will need to be different thicknesses. We will see what happens.
