I bought mine used with 190 mi. on it for $4k., a great deal and one that I did not have to think twice about.
I'd say anything in the $4-5 k range is very good, esp. from a dealer, with warranty and all.
This is a substantial bike, and very easy to get $5k of fun out of...possibly on your first ride.! Consider the cost of the Porsche, Vette or Jag that would give you the same performance, and consider also the looks from drivers in cages at a stoplight:
Occasionally you will get the "Poor demented fool" look...but most often, and commonly from the overdressed business people, you will get a look of pure envy...for you ARE having much, much more fun than they, even if only riding to work.
