On my 2015, I quickly replaced the stock screen with a Yamaha Touring Screen, and that was better, but lots of head-level buffeting above 50mph even when fully raised. Looked at forum discussions here and was thinking about Cee Bailey or National Cycle V-Stream, but got wind of California Scientific (CalSci) and went to their shop since they're pretty close to me. The owner Mark is this brilliant scientist who will suffer your dumb questions about windscreens then school you in aerodynamic physics principles that will make your head spin and then talk about something he REALLY likes, like Einstein or the Higgs Boson, or Comparative Religion or the German Shepards he rescues. You just have to take one look at CalSci's website (www.calsci.com) to see what I'm talkin about. All the young dudes that work there, including his son, seem to be equally bright, physics-driven geeks. The point of all this is that they have brought a very high level of aerodynamic physics math to the design of motorcycle windshields, and it shows in the product. They don't look particularly different but somehow the shapes and contour solve the issues I noticed with the other screens I had, namely buffeting and lack of smooth airflow around the screen.
They make FJR screens in "regular" and "extra wide" widths, each with heights of medium, large, and XL, so you've got six choices.
I wanted a good area of quiet air, and I tried the Xwide Large, and Xwide XL. I tried the XL first, returned it for a Large, then returned that one and went back to the XL but asked him to modify (shorten) the bottom outside corners and that modified shield is what is pictured below. Bottom line: the corners on the bottom of the shield are there FOR A REASON, and I should have just left it alone! Dumb Me, having to screw with a good design. Not the end of the world, but my mod just puts more wind on the grips than there was before, but overall this is just a great designed shield.
The main thing I notice is how well the shield moves wind smoothly over the top of my helmet even with the screen at it's lowest position. On the OEM Touring screen, if the screen was at lowest level and I was looking just over the top of the screen, it's like there was no shield there at all and the wind just blasted me. I mean, I like being out in the elements and feel all that air motion around me, but I just don't want constant loud wind ROAR in my face. Hard to think. So that's where I'm comin' from, Savvy?
With my CalSci, I have good flow over my helmet with screen at lowest level (when I'm looking just over top of screen) until I get above about 50mph, then I just raise the screen so I'm looking through the top 2 or 3 inches of the screen and that blocks all the wind to my helmet up to about 75mph. I finally noticed I was doing my 70 mile loop yesterday with my visor up since there was no wind in my face, just stillness. I really never need to raise the screen up all the way now, but I like the width of the screen up high that comes with the "Xwide-XL" size I settled on. The "Xwide-Large" tapers more as you move toward the top. This Xwide-XL screen now on my bike is 25 inches in tallest dimension (not in middle of bottom "V") and 21" wide just below top of shield and 25" wide at widest portion below. That's only about 2 inches taller than the Yamaha Touring screen, but also quite a bit wider up high, and that combination along with the shape design just creates a much different environment behind that plastic.
But really, just check out CalSci's website, learn about "Von Karman's Vortices" as it relates to airflow around motorcycle windscreens (look for the "all about our windshield designs" blue link on the FJR 1300 page) and see what happens when someone who ACTUALLY understands both Einstein's theories of Relativity (General and Special) puts his brain cells to work on windscreens. Cheers!
Here is the Yamaha OEM Touring Screen:

And this is the CalSci XWide-XLarge screen (modified by dope me. The Unmodified would have shoulder corners at the bottom left and right to block air over grips even more):
