It takes a certain amount of energy to push a motorcycle through the air. So a Burgman scooter is going to take a similar amount of energy to push it through the air as a Ninja. Most bikes get in the 40s on the highway. Any of my 750, 1000s and 1100s I've owned all over the years have gotten around 40 highway mpg. The best mileage bike I ever owned was a Sportster. It got 50+ regularly. You might consider a Sportster. They are handy around town too.
