BMW has been producing the GS in one form or another for more than 30 years. Steady evolution has seen an ever growing list of features and capabilities.

While the advantages to reliability and performance are well understood on street bikes, if you ‘re going to ride a big bike like the GS in the offroad manner for which it was intended, keeping things simple has its advantages also. No one wants to deal with a leaky radiator in the middle of the desert. BMW makes the case that it hasn ‘t forgotten the GS ‘s roots in this series of three development videos.
