Sluggish acceleration above 5000 RPM

[36654]

Posted on the old site - asked my mechanics about it. The 2016 bikes started arriving without the circlip.
Speculation was that its omission was intentional and from the engineers, to allow some additional, needed freedom of movement.

I had the shaft service done last Tuesday.  The mechanic said the c-clip was installed on my bike and he's never seen one without the clip.  More fodder for the confusion........
