Good mileage for a sport bike???

10K miles on a 97 is very low mileage. People typically don't put as many miles on a motorcycle as they would on a car, but you would generally see more like 30 or 40K miles on a 14 yo motorcycle. 3 year old motorcycle, I'd expect around 15K miles and 20-25k on a 5 year old bike. There are a lot of bikes out there where riders will only put around 1500 miles on it a year.

10K miles is so few miles on it that it probably hasn't been serviced much, and has spent most of it's life sitting. Extended sitting isn't good for any motorized vehicle. Be sure to check all the lines for cracking, and you may have to replace many of the seals, but the motor itself probably has very little wear, and Hondas are notoriously reliable. Be sure to check nada.com or kelly blue book to make sure you are getting a fair price.

I should also say that these are 'sportbike' miles. People who ride BMWs or Goldwings will easily put 10K or more a year on their bikes. Sometimes WAY more.

Also also, once you start getting into the 40-60K mile range on a sportbike, it is very important to have a compression test done. At that mileage, head gaskets start to get a bit dodgy, depending on how and how often the bike was ridden, and how well it was maintained.

You'll get about the same gas mileage on either bike whether it's 3 or 5 years old. I had a CBR F1 waaay back in the day (when it replaced the Honda Hurricane) and I got 35-40mpg back then. I've ridden Suzuki ever since and it's also about the same. You'll get around 120-150 miles out of a tank depending on how much you like to twist the throttle back. :) If you just cruise on the highway I'm sure you could get 40-45 on newer bikes but that's really conservative.

3-5 thousand a year or more
