Considering the controversy surrounding the high-speed handling of the the K1600GA and K1600b, I thought I'd post a link to this famous old Dunlap Tire video discussing wobble and weave handling issues. If you haven't seen this video do yourself a favor and watch it. While dated and poor quality video, the information is priceless. Some cool footage of vintage 70's Japanese and a BMW R90S as well! You can skip ahead to the 4:05 mark where Mr. Walker starts to talk about wobble and weave handling issues on motorcycles:
