crappy, pointless form of 2-wheeled transport.
modern scooters are usually between 50 and 250cc, feature a "step through" frame and small wheels (8-13 inches in diameter, usually around 10).
50cc ones are most common among teenagers. most are 2-stroke, and make a noise akin to that of a hedge-trimmer. 4-stroke ones are available, although incredibly sluggish.
scooters tend to be much slower and lacking in power than
motorcycles, and usually have "
twist and go" transmission.
they can be made to go quite fast. but most of the really fast ones are in such a high state of tune that they don't last very long, and constantly suffer from
mechanical problems. and besides, who wants speed on a machine that doesn't have gears, weighs about as much as its rider and has such small wheels? no matter how much you dress up a turd, it's still a turd.
