K1600B Wobble

I’ve been considering a used 2018 -19 Grand America. I’ve read on this site that the 1600B has a dangerous wobble at highway speeds especially when encountering cross winds and truck turbulence.
Has BMW resolved this issue?
Does the GTL also have aforementioned proble?

The GT and GTL does not have this problem.

The K1600GA is speed limited to 100 mph.

IMHO the only reason BMW would do this would be because instability was detected in wind tunnel testing.

The GA design added floor boards which IMHO contribute to front wheel lift at speed. With the GA this is made worse because the Top Box is mounted so far back which again will cause the front wheel to rise at speed. This becomes very noticeable on any motorcycle in turbulent air around large vehicles, or in cross winds.
I have a 2021 GTL, and on the freeway above 80, it does wobble, more so around a big truck or a very windy day. I did change my stock windshield to California scientific Extra large windshield which I think made the condition worse, also I have aerostarstar wings. Once the winter is over I’m going to put back my original windshield which I think wobbles less. It never feels dangerous but it does take a little bit to get used to.
