In the global culture of the motorcycle, BMW occupies a unique place. As a brand, it is the envy of even Harley-Davidson. It stands for a subtle balance of high quality, utmost reliability, supreme comfort, the best of German engineering, exquisite taste, and a breadth and depth of being hip from Rodeo Drive to Manchuria. Moreover, it's Europe's largest and most successful motorcycle by a measure.For the past few years it's best selling models, by far, are those from the GS series - the subject of this book. GS is the abbreviation for Gelandsport - off-road. Strictly speaking most GS models are capable on-road and off-road and are more frequently, today, being described as 'adventure motorcycles'. What is certain is that the vast majority of the best selling GS model, the current 1200 boxer twin, are used on-road! This is a catalogue of all GS models - a translation of the best-selling "German, Faszination BMW GS" and now in its fifth edition.
