A Gelände/Straße Adventure fansite by Edgar Stokka
Facts
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. On 27 July 2007, the BMW R1200GS and R1200GS Adventure reached a production record of 100,000 units since its launch in 2004, making it the most popular BMW motorcycle. In May 2009, the 500,000th GS was produced, a R1200GS model.
