I demo'd one a few weeks ago, also road my V to the dealer and home again.
I couldn't agree more on the smoothness, just incredible. The road version I road also had an Arrow can and again it sounded sweet, not loud just plain cool. The windshield worked well in stock form also.
I felt the V was snappier and also handled much quicker. I think that is what is standing in my way, I just love how quick the Versys handles and it has me smiling alot, the Tiger handles well, but for me it just didn't seem as fun. I think about it alot but am too affraid I will miss what I have to drop almost twice the money.
They did invite me to come back for another test ride, and they also said they had one that was pre-ordered that the guy back out of, so they had one ready to go. It was the ABS version so that added another $800 to the cost.
As far as seat hieght, I would say it's real close to the Versys, didn't feel any different to me. I'm 5'8", so I wasn't flatfooted on either one.
One other thing that has me scratching my head is all the creature comforts I added to my Versys, heated grips, XM radio, GPS, two power outlets... all this stuff mounted nice and clean on the Versys, the Tiger has a more minimalist dash which doesn't have alot of mounting options. This is surely a small problem that I'm sure could be overcome with some creative thinking...
Great bike for sure!
