New BMW R1200GS Showcase Presentation [Video]
It's all down to the liquid cooling and the new riding modes, of course. If you thought that the 2013 R1200GS was all about liquid-cooling, you were wrong: the video explains how the engineers used the new cooling solution only for some of the most temperature-stressed areas, leaving the cooling fins to do their job just like they did until now.
While we tend to trust BMW's testing, we cannot help a dash of skepticism preventing us from hailing the new GS until the real-life, harsh and unforgiving testing is done by the riders themselves in the wild. We expect good results, anyway, but for the sake of objectivity we can't say a bike is great before it returns in one piece from the "long trip".
As for the easier cycling through the riding modes and traction control, a simpler, more rider-friendly operation is truly great, and we're happy BMW has finally understood that “complex” must not necessarily be “complicated”.
