I don't get why people complain about the vibrations on the 4 cylinder Ks. The motors are not as well balanced as the K75s but as long as you keep the TBs synced they're fine. And people who get "pain in the palms" are distributing way too much weight on their arms. I've never had any issue doing 12-14 hour days on my 4V Ks. And I've had all of them - K1, K100RS4V, K1100RS and K1100LT.
That Brune K1 is more for show than go.
