My friends and I have Honda Elite 150's. We took a ride to the summit of Mt. Evans (14,264) on our scooters. My MPG is usually in the low 90's without regard for conservation. The top speed has been 65 MPH indicated, but the scooter is most comfortable up to about 50. Above that, the scoot seems to be working pretty hard. My friend Janet has over 35,000 miles on her red Elite with only oil, air filter, and tire changes. She did roast one drive belt at about 20K. My Elite has 15,000 with no issues except needing a new battery. It's hard to believe, but this scooter qualifies for "vintage" license plates next year!
