My Kinetic TRF is advertised to get 150 mpg. Years ago I had a little 70 cc Honda that had 3 or 4 gears and could climb up the hills.. no problem. I don't remember its mileage.. but it was good. I'm wondering what is the mpg of smaller motorcyles.. say up to 250 cc? and 2 strokes compared to 4 strokes? (that 70 cc Honda was a 4 stroke). Thanks for all answers.
