Had stock windscreen on with Shark rsr2. shook me so bad i couldn't see so I can relate to why some inmates have such an issue with it.
I'm 5'10" athletic build
Now I"m rocking a uvex enduro lid with the rally raid screen from ktmtwins. Also have the HDB handguards with integrated mirrors. Smooth sailing. I'll get slight buffeting in really strong crosswinds but don't give a S$%^. I don't understand putting a big tall windscreen on these bikes, except for cold weather. Keep it short and you should be good to go.
I'm going to try the no buffet windscreen in post 3 of this thread.
