Are the vibes 'unusual' or just ones that come with the territory of riding a big single?
The Ten is the first big thumper i've owned and at first i didn't think it was normal! Got used to it a bit now although i took my friends zzr1400 out yesterday for a spin, wow, what a piece of work it was..
I find that the really intrusive vibes chime in at about 4.5 - 5k rpm.
