Hi all,
I have a 2010 575 with a BAFANG 1000 HD mid motor which seems to have developed a very slight, but noticeable amount of shudder with play/movement sideways, in the rear triangle. This is apparent when changing gear in riding mode only.
Can this down to worn bearings or perhaps just in need of tightening torque wise.
Anyone out there with experience of similar issues with this model built around that period with or without motor fitted?
Thanks, Oscdav.
