Motorcycles are gas pigs? I get 50mpg minimum at an average of 75 mph. There is a reason third world countrys are filled with bikes they are cheap, easy to maintain, and get great gas mileage. Unless you are reffering to a boss hoss( v8 powered bike) or some of the ludicrous bikes produced in the last decade with motors over 2000cc (110ci). My bike is more efficient than those god awful prius' and you don't have all the toxic materials from making the batteries,wiring, and plastic bodywork
