Motorcycle fuel economy benefits from the relatively small mass of the vehicle, compared to its passengers and to other motor vehicles, and subsequent small engine displacement. However, poor aerodynamics of exposed passengers and engines designed for goals other than fuel economy can work to reduce these benefits. Riding style has a large effect on fuel economy: some riders report being able to double fuel economy by using low accelerations and lower speeds than usual, although this is the extreme case.
Fuel economy varies greatly with engine displacement and riding style ranging from a low of 29 mpg (U.S.) (8.1 L/100 km) reported by a Honda VTR1000F rider, to 107 mpg (U.S.) (2.2 L/100 km) reported for the Verucci Nitro 50 cc Scooter. A specially designed Matzu Matsuzawa Honda XL125 achieved 470 mpg (U.S.) (0.5 L/100 km) "on real highways - in real conditions."
