Question about engine vibration

Question to you K12R owners: How much engine vibration do you experience when you tach out the motor? I've read a couple reviews of the K12R that mentioned coarse vibes. Are these reviewers smokin' something, or have you noticed the same thing?

When I first got the KR it had a much coarser motor which since the updates has been rectified. Starts/idles and goes so much smoother, (perhaps the milage as well helps I've done a shade over 13K now). I'd have not said the vibration was worse than any I4 when you're going hard.
Certainly in comparison with a friends Blackbird, even he pointed out is was smoother...

My experience has been that the higher I get in the rpm range, the smoother the bike feels. The only vibration I really notice in passing thru 6-7k rpm's, then it smooths out. I would say my bike loves the 7-10.5 rpm range the most. Also, version 6.1 software.

I notice a bit of vibration between 5-6K revs. I was not aware of this before the latest update was downloaded at last service, but I also notice the motor is much smoother overall and especially at idle than it was previously.

...were horrendous at 6k rpm before 7.0. Now it's gone, but I do notice weird vibration/lash sound emanating from the gearbox or engine or the body work at around 2500 when I downshift comin' up to a light. I took out my earplugs the other day and really noticed it.
Otherwise, 3500 rpm is the smooth spot with 1400 miles on the clock.

Yong, my KS is perfect. It has no vibration anywhere, not even at idle.
Well, actually, that's not entirely true. It will vibrate slightly on hard gravel roads.
