       THE MOTORCYCLE HAS EVOLVED from a motorized cycle—a basic

       chassis (see pp. 364-365): the new Werner became the basis for the
       modern motorcycle. Motorcycles are used for many purposes—for
       commuting, delivering messages, touring, and racing—and different
       machines have been developed according to the demands of
       different types of rider. The Vespa scooter, for instance, which is
       small-wheeled, economical, and easy-to-ride, was designed to meet
       the needs of the commuter. Sidecars provided transportation for the       Alloy
       family until the arrival of cheap cars caused their popularity to      crankcase

       appeared in 1969. Despite advances in motorcycle technology, many
       riders are attracted to the traditional looks of motorcycles like the
       twin-cylinder Harley-Davidson. The Harley-Davidson Glides
       exploit the style of the classic American V-twin engine, where the                      Passenger
