Yesterday was the end of my month-long, 5.5k mile test ride.....
With some obvious subjectivity, the bike did not have the wind-induced death wobble issues as I previously experienced, or at least not nearly as bad. However, in certain wind conditions, the bike was still tossed around quite a bit. The worst case scenarios were with a strong cross-wind and trucks.
The turbulence coming off a truck with little or no ambient wind was minimal and the bike was stable. But, oh boy, hit a strong cross-wind and the truck turbulence threw me around like a rag doll, just like my previous experience, but without any significant front end wobble added to it after tightening up the head bearing a bit.
I do have the wide F4 windshield, which is 4" wider, on each side, than stock, so 8" overall. At this point, I'm thinking that is definitely a factor. I will be looking for a stock windshield to see if that makes a difference.
I rode a pure stock '99 RSV from '99-'02, including one such trip as I just completed, and do not remember having these wind issues. Of course, age-related memory issues could be part of that too.
