Many standard 4-stroke motorcycles get 55 miles or better to the gallon. Two-stroke engines, which are more powerful for their size but require more maintenance, can achieve 100+ miles per gallon on a 100lb vehicle like a moped, or up to 170 miles per gallon on a motorized bicycle.

Many standard 4-stroke motorcycles get 55 miles or better to the gallon, but require regular maintenance similar to most automobiles. 2 stroke motorcycles, however produce much more pollution, can achieve great mileages, over even 100-170 mpg. Their rudimentary design achieves twice the power, but are less refined than four strokes.
