Hi, I meant to post an update earlier. As usual, the dealer did not find anything unusual. Perhaps that’s how they are....
The vibration is obvious more so accelerating slight uphill. I’m quite an observant person, so it is definitely there, just being able to replicate it for the mechanic.

The Tig on the other hand, should be super smooth at all times, like my 2015 r line i traded on this 162 r line...i will keep you posted.
Could it be the tyres? I've got Pirellis.....
Could be that your tyres are cold and not getting enough bite?
I have continental's on mine...doesn't feel like tyres. It responds to increasing torque. It might end up being exhaust resonance . Who knows. I'm not sure these types of vibrations are actually covered by warranties anyway....will keep you posted when i visit the dealer.
If I was told something like that I would instantly say let's go for a ride in one of you stock vehicles and see if it does the same thing.Quote:

Have you tried to turn it off and see if you still get the vibration?
hi, and thanks for the reply.Quote:

Been thinking about this one again. Took my Tiggy for a bit of a strap to see if I could replicate what you are describing.
If I'm booting it I can get a little vibration through the wheel and seat. And feel it somewhat through the footwell. It's not a massive amount.
What I'm thinking is the engine movement due to torque is loading up the dogbone mount and causing the vibration to be transmitted. It's similar to the vibration felt when adding one of the dogbone inserts and it's specific to the Rev range where torque is greater.
