We have the Kawasaki Ninja 650, and the Versys, that use the same, or at least a similar parallel twin 650cc powerplant. Both bikes received pretty good reviews over here, but the styling and the fiberglass work doesn't look nearly so clean as the euro models.
The rear shock is offset - makes for easy access. All the testers over here complained that the seat on our version is not good for anything over 1 hour riding time at a shot, and the passenger accomodations are worse. But the power plant and handling is quite pleasant.
