2020 BMW K 1600 B Steering Problems

At highway speeds when approaching any large vehicle the motorcycle oscillates to the point of loss of control. This occurs at distances up to 300 yards. In brisk cross winds on open road the same condition exists, but is multiplied in close proximity to other vehicles. I had the bike inspected and serviced by a BMW dealer and nothing mechanical was found. My background is in aviation, and in my 30 years experience this acts and feels like an aerodynamic instability issue. I have been riding for 40 years and outside of "tank slap," when racing I have never experienced anything like this on a road bike under normal riding conditions. There are many forum posts with the same concerns, but no viable solutions. BMW has not been helpful.
