Vibration from engine after 8000 miles

Hey, I got a 2008 Model Versys that has about 8000 miles and since last week I can feel some vibrations that come from the engine or around it, I'm not talking about the vibrations from front plastics.
All engine fitting bolts have been checked and no issue.
The vibrations comes only when clutch is engaged, on whatever gear I am, and can be felt from very low rpm.
Has anyone had this, any clue .. ?

Thanks!

Does the drive chain tension vary as you rotate rear wheel off the ground, engine stopped? Are you only feeling it more in the footpegs? Have you changed footwear at about 8000 miles? Is it a pulsating or steady vibration? Is the vibration frequency relative to travelling speed or engine speed? Can it be heard too?

No release bearing on a wet multi-plate clutch, but I agree that the clutch is a possible cause.

Have another look? - Cable/release shaft/push rod/release bearing/pressure plate, as standaard on millions of bikes.

The clutch release shaft needle bearings would only affect clutch release actuation.
The clutch spring plate bearing (could also be called release bearing ) turns when clutch is released (disengaged), and wouldn't cause vibrations with clutch engaged... A bad spring plate bearing would be noisy when clutch is released.

Frankly, I disagree with your original and subsequent points but rather rthan get into a another lengthy debate as elsehwre, you seem to agree, after an edit, there is a bearing afterall, so I;ll leave it there.

The real point is; I'm more concerned about throwing out suggestions to this guys problem rather than I am finding others sugestions wrong, Short of some distatrous advice I dont partuclary care who's right or wrong frankly, noting I made no comment about your original sugestion for example. Overall, with repsct to the OP, I take any noises/knocks decibed online or face to face with a pinch of salt as are notrioulsy diffuclt to describie/isolate. Not least as often clutch engage/disenege is used interchangably anyway, but taken at face value, I give a brief suggestion knowing it will prob be something completely unrelated anyway

I too find the descrition given by the OP somewhat unclear, but it sounds like this is a problem when the bike is in gear and moving. If that's the case I would be looking at the chain and sprockets.

I think the same guy is posting on the UK forum about the same problem, and he's active there.

Hello guys!
Thanks for your feedbacks, sorry for late reply I couldn't check forums last couple days.
The vibrations are steady and seem to be linked to the traveling speed, can be felt in foot pegs as well as on the handles.

Yes I posted also on the UK forum, to see if I'm really the only one with this problem.

Clutch is engaged and transmitting power from the engine to tranny when you're not pulling clutch lever in. Pulling clutch lever in releases (disengages) clutch...

Have you checked if your chain tension changes as your rotate rear wheel, with rear suspension fully extended to get proper measurement?

As Invader says above.

Sounds like a chain which has become very dry at some previous point in time.
It overheated due to friction and destroyed some of the O-rings and lost all its internal lubrication at curtain links, ie got Sha**ed and had become very loose. You have then adjusted and oiled it, but it is now giving you these symptoms. But who knows - just my 2d.
