Wow, that's a great MPG! I don't think mine is there yet, but I think I have to do more blowout highway driving. I'm just over 700 miles on her and will have to do some servicing at 800.
I agree, though, she's a great scoot.
What kind of gas are you using? I've been staying with Plus, but I don't remember if the service mechanic at the dealer ship suggested premium or not.
