2024 BMW K 1600 B

I purchased this NEW BMW motorcycle on 7/26/2025. On my ride home from the dealership the safety incident occurred on the freeway trying to pass a semi with a trailer. All factory original equipment and only me on the motorcycle. While passing the semi the motorcycle started shaking out of control and I had to slow down to 40 mph in a 70 mph zone trying regain stability of the motorcycle. The dealership was now closed when this occurred. There were no freeways located by the dealership to test this scenario prior to purchase. I posted what occurred on a k1600 forum that night about the problem. I received hundreds of replies saying replace the windshield but it was a common problem even after replacement. Sunday 7/27/2025 I ordered a windshield. When the dealership reopened on 7/29/2025 I called to see what BMW suggests to correct the problem. The dealership told me BMW had no fixes. I said then I would like to return the motorcycle if BMW does not have a fix. They told me they would not return it, but that I should try and replace the windshield with a Klock Werks or 7 Juress windshield and that should fix the problem. I installed the windshield and with no crosswinds was able to pass a semi trailer on the freeway without incident. I felt more confident and continued to ride with hesitance. Then I rode with crosswinds and other traffic and tried to pass the tractor trailer going 60 mph and it did it again. I removed the footboard and tour pack/top pack. After removal it is no longer life threatening to pass a semi in cross winds. My problem is that being a new bike with all the equipment from the factory that the motorcycle should be safe to ride in any road condition. As an experienced rider of 30 years my fear is that in rain should this occur a rider could loose control and have a wreck. BMW needs to fix this problem for rider safety and the safety of others on the American road. I would really like the manufacturer BMW to return this motorcycle.
