"Comfortable" highway speed?

[TR]

Kerry:

At one time or another I've "decided" on a Concours, an FZ6, a V Star 650, a GS, a YZF600, a Monster, a V-Strom (650 version), a Moto Guzzi Breva, a Bonneville or Thruxton, a Sportster (883), a SV650  and probably some others.

Well, if I could buy right now any of those bikes with no money problems I'd buy the YZF600R, I've read it's a great all arounder, from a GSer point of view, with ergos similar to my faired GS, extra power and a convinient 2 up seat. Of course the best bike for you depends on other issues we don't know about, like money, maintenance, your skills, etc.
