From Thorsten's list above it sounds like the bike is leaning back on the rear suspension and taking weight off the forks; similar to a steering head wobble under high acceleration on a track. The symptom that doesn't fit that theory is instability behind another vehicle, except that buffeting between intense vacuum and intense wind blast is likely to upset the chassis on anything softly sprung/damped.
Any aftermarket suspension on your CB, or service to the factory boingers over those 100,000 kms, Thorsten? If you ride regularly at those speeds I would definitely stiffen up both ends and go to heavier fork oil.
