Guys,
what is your gas mileage on your Ninjas 250? Does anybody have an idea how long those engines last at ordinary (not high-rpm) use?Do you run on premium fuel?

i get about 57 mpg consistantly on my 08 250r... if i take it slow i'll get near 60.mpg i burn premiem and haven't had a problem yet. i pushed near 10k rpm in the first 100 miles and still going strong at 2k miles. my break in was about 500 miles before i hit it hard,

I see. The 08 has a different cylinder head and I guess is more powered, thus the lower gas mileage. So far, I have not dropped below 60 mpg, but I don't ride it hard. Just taking it easy on everyday commute. If somebody gets an awesome mileage, please share your experience.
