I recently purchased my first Spyder after drooling for 8 years and have had vibration problems from day one. Usually around 56 mph and again at about 75 mph. The dealer had the "ace" spyder repairman ride it and he in fact did say there was a problem. They balanced the wheels, traded wheels from another and did it a second time and basically told me it was fixed and to go away. There is still a vibration that is bad enough that I can't tell what is behind me when I look in the mirror. I would like to hear from other riders if they have had a similar problem or should I just let it go and try to enjoy the ride. I am getting used to it --but it's still there. l_thanks
