BMW Motorrad considering a 6 in their next Sport bike

BMW Motorrad Concept 6. Six-cylinder power units offer not only smoothness and refinement, but also superior power and performance. When considering Motorcycles, depending on the way the engine was fitted, six cylinders in-line inevitably made the engine either very long or very wide, creating disadvantages in terms of the running gear, weight distribution, and the center of gravity. A further drawback was much higher engine weight usually setting off the benefits of extra engine power.
