The stock windshield is useless. Since it is short and aligned with the fork, wind is directed straight at your helmet causing extreme wind buffeting.

I am only 5’10” and I get buffeting straight at the helmet. So much for German engineering.All depends on your height. If I duck down 2-3 inches the buffeting goes away. I’m 6’4” though, I added an MRA touring lip to mine. In the tallest position it adds about 6 inches to the screen. No buffeting and blocks a lot of the wind in colder weather.
I imagine if someone is shorter or even average height especially in the torso, the buffeting wouldn’t be an issue. For those taller or who want more coverage an extended lip is a good option. I’m also looking forward to some aftermarket screens becoming available.
I’d suggest trying moving around to see if it is buffeting from the screen. On the bike torso height and arm length rather than overall height will determine where your head position is. Moving slightly foreword or back can also really change the feel.I am only 5’10” and I get buffeting straight at the helmet. So much for German engineering.
No, it doesn’t. It is the windshield.Helmet / Jacket combination makes a huge difference on buffeting.
It is the combination. If the windshield edge is hitting the right spot on the helmet and the kind of helmet is more susceptible to buffeting it will be more intense. Generally speaking full face helmets are less affected by buffeting as they are smoother themselves. An open face has exposed edges which catch air and thus light buffeting on a full face could be intense on an open face. A modular in the open position has even more edges to catch air and shake your head. Thus the shape of the helmet directly affects buffeting.No, it doesn’t. It is the windshield.
That’s not how aerodynamics work. Air hitting the helmet isn’t buffeting. It’s caused by the vortices where 2 different airflows come back together. The position of those vortices and how volatile they are depends on the shape and surface elements of the displacing features. On a bike, the windshield is one of those features just as is the rider (and their gear) and thus affect airflow. I wish it was simpler… would have made my college fluid dynamics classes easier.This is getting retarded now. When the windshield is too short and it is angled with the fork, it will deflect the air right into the helmet. What does a jacket have to do with windshield buffeting? A Harley Heritage Classic or Road King windshield is vertical, not almost laying down like this garbage BMW produced.
I would like that BMW have had at least the half of your knowledge. That Classic Windshield sucks, that's a fact.That’s not how aerodynamics work. Air hitting the helmet isn’t buffeting.

I’m sorry the R18 doesn’t work for you. Some bikes work out of the box for one person but not others. Some can be addressed with minor tweaks using the techniques I’d described. Take another look at a Road King’s screen: https://www.harley-davidson.com/us/en/motorcycles/road-king.html. It is also parallel to the fork, not vertical.
