For BMW to step into a new realm of performance required extensive research and development. The K 1200 S is the result of a five-year process that first looked at the overall concept of a high-performance road bike and considered several options along the way to building a sophisticated aluminum-frame sporting model with an innovative inline-four-cylinder engine.

Central to the development of the K 1200 S was the realization that the inherent benefits of BMW's customary designs - the opposed-twin Boxer engine and the longitudinally mounted four-cylinder in the K series - could not be ignored in the new model. And a primary advantage of BMW design has been the centralization of motorcycle mass and, particularly, the desire to keep the overall center of gravity low. Such a philosophy ensures that the motorcycle is highly maneuverable and yet remains completely stable and composed even while traversing rough roads. Furthermore, a low center of gravity makes the motorcycle more comfortable for riders with shorter inseams. Take two motorcycles of equal weight, and the one with the lower center of gravity will feel, subjectively, much lighter and confidence inspiring.

With the decision made to develop the K 1200 S with as low a center of mass as possible, BMW engineers set to work creating inspired and uncommon solutions.
