The Sportster is a line of motorcycles produced
by the Harley-Davidson motorcycle company. The line
was first introduced in 1952 as the Model K Sport
and Sport Solo motorcycles, and has been produced
continuously ever since. Sportster
motorcycles are powered by true 45 degree V-twin
engines, that is, both cylinders share a common
crank pin. The motor and transmission share the
same casing, which until 2004, was also used as
a stressed member of the frame. 2004 and later Sportsters
use a separate frame, and rubber mounts to isolate
engine vibration. The Sportster line of motorcycles
has gone through three general stages, identified
by the engine model used to power the motorcycles.
