Thanks for all the answers, seems I'm not alone then.
Like I said it's not bad but the niggle it could get worse has me a little worried for sure

 I was wondering the same.
 
 I haven't noticed it in mine. Maybe I haven't been paying enough attention.

Thanks!  Guess now I'm going to have to (I'm ashamed...) to look up what the Versys much-touted 'slipper clutch' is, and how it works.  Clearly, on takeoff the clutch is doing some slipping that's designed in...
Will research, and I'm sure you guys know it inside out.  Should have looked it up sooner.

See this wikipedia link for further details - HERE  :028: :028:

A slipper clutch (also known as a back-torque limiter) is a specialised clutch with an integrated freewheel mechanism, developed for performance-oriented motorcycles to mitigate the effects of engine braking when riders decelerate hard.

 I miss the engine braking of the Mk1 650 on the big V.  Almost as good as reverse thrust.

clutch shouldn't slip on takeoff,
basically its to stop the rear wheel locking up or skidding if you change down at too high a revs,

If you watch race bikes sliding the rear wheel out ( backing it in) going into corners, that's the slipper clutch helping them do that, they basically can stamp down the gears without the fear of over revving the engine and locking the back wheel up.

We also have what is termed a "slip and grip" or "assist and slip" clutch  :028:

As talked about @ 1:54 in this Video  :028:

I experienced this issue with my Mk2 Versys, but never on my previous Mk1; and so I decided that it must have been something to do with the slipper clutch and a bike problem.

But, the problem was not with the Mk2 Versys but it's pilot, as I realised that I was releasing the throttle just a tad too soon between gear changes. In effect I was loading the slipper clutch, and as I grabbed the clutch lever and began applying pressure I was feeling the slipper clutch, well slipping.

So I now pull the clutch in just before releasing the throttle, and the clutch lever has a normal feel again.

That sounds like a straightforward explanation

Slight clutch  'judder' has been reported/experienced  by some owners with new bikes when first setting off, it's a phenomena that seems to resolve itself after running in is completed, I'm not saying there is a direct connection however it may be  :notsure:
