The BMW GS enduro bike has been a symbol of freedom and adventure for three decades. The secret of the motorcycle's popularity is that it perfectly blends sturdiness and off-road maneuverability with long-haul comfort. One of the GS' biggest fans is rally driver Jutta Kleinschmidt.She started her career by winning the women's race at the Dakar Rally on a GS. A visit to this year's GS meet at Garmisch-Partenkirchen is a good way to find out just how well-loved the classic motorbike is.
