I get anywhere from 50-60 miles on a tank of gas (1/2 gallon)
Of course your size and the weight of your bike, and terrain and also if you ride wide open full throttle all the time that will also kill your mileage.
I do not know of anybody who gets 150mpg...mine jumps between 100-120mpg. Depend on where I ride and how hard I push my motor.
