My experience with windscreens for normal riding - as opposed to tucked into a racing-type position/fairing - is that they don't work!
Unless we're talking about a dedicated, serious touring bike - Gold Wings, big BMW Tourers, etc, all the usual windscreen does, IMO, is shift the wind blast from a manageable, in your chest area, to a miserable, helmet-buffeting pummeling that has your eyes vibrating after an hour at interstate/motorway speeds.
I have tried multiple windscreens on various bikes - including 4 different ones on my BMW R1200RS - and none of them provided anything useful. I've found that the most important thing is to keep a helmet either in clear air or completely shrouded by the windscreen. That requires either a very low windscreen - like the Cafe's, a very tall one that you have to look through, or tucked in on your Ducati Panigale
One issue that can be confusing is that one windscreen can be reported as working great by one person while another thinks it sucks...even though both people are the same height. Of course, this can happen for two reasons - a different 'tolerance' for any turbulence, and the fact that two people of the same height can have dramatically different leg/torso sizes. So their head height above the seat and in relation to the windscreen is quite different even though standing side by side they may be of identical heights.
I have ridden behind fairings that did a great job but, in every case, they were too ugly for me to consider. For those of you old enough - the Vetter Windjammer was on a lot of Honda 750's back in the day; it worked great but left a bit to be desired in the looks department...
You might be able to find a used one! https://farm8.static.flickr.com/7038/6962435333_7a81b0e410_b.jpg
