Having recently picked up my 2008 XT660Z Tenere and having read various posts on cush drive rubbers failing, thought I would have a look
at mine today. If I grab the rear sprocket and attempt to move it
clockwise/counter clockwise, there is quite a bit of movement. Does
this mean cush drive rubbers are worn out? I would have guessed that
there should be no movement at all. The Bike has just over 10k miles
on the clock. If they are worn, is it best to replace with an OEM item,
or is there a more robust alternative available?
