Just a few weeks ago, BMW announced the arrival of the newest GS bike, the 2014 R1200GS-Adventure. That motorcycle is arguably the most sophisticated adventure bike the world has ever known. That doesn’t necessarily score big points with all riders. Those with a penchant for simplicity eschew all of the fancy electronics as unnecessary, even a liability. It doesn’t get much more austere and simplistic than the R100GS. These legendary machines, most pushing into their third decade, are still chewing up miles. This 1993 GS has but just 36,000 miles. That’s nothing for a bike like this. That’s not even a lap around the globe. For $5,700, less than the price of a KLR, you could be rolling on your own shaft-driven boxer twin.
