Hi, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.

Initially, determine if the vibration is dependent on engine speed (RPM) or on scooter speed (MPH)...accelerating or decelerating or constant speed...or when braking.

Expert:  Louie replied 2 months ago.

Still, proposed preliminary checks (if have not been done) on possible suspects:

  • • tire pressure;
  • • tire thread wear;
  • • sidestand and/or its rubber block;
  • • swing arm long bolt/nut;
  • • variator.
