The BMW GS
series of dual purpose off-road/on-road BMW motorcycles
have been produced from 1980, when the R80G/S
was launched, to the present day. The GS refers to either Gelände/Straße
(German: off-road/road) or Gelände Sport
. GS motorcycles
can be distinguished from other BMW models by their longer travel suspension
, an upright riding position, and larger front wheels – typically 19 to 21 inch.
