"Aerodynamic components such as the twin-tipped engine spoiler and the air guide elements derived from the design of the new S1000 RR Supersports," BMW says, "bridge the gap between functional and clearly visible technology and the smooth design of other body elements.". Carbon fibre fuel tank, hollow camshafts and lightweight connecting rods all underscore the emphasis on shedding weight. This should bode well for the next king of the touring segment.

The inline 6-cylinder, based on the K1300 55-degree 4, has an additional two cylinders, but is still very compact. The displacement is rumored to be in the 1600-1700cc range.

While all the talk is about the sport bike shown, with a single throttle body, this engine is clearly destined to appear in a touring platform. According to sources at BMW "The engine will produce about the same power as BMW's 1.3-litre straight-four but torque will increased. The engine offers 130Nm from 2000rpm but can rev to almost 9000 rpm – unmatched in the touring segment – and fuel consumption will be on par with a four-cylinder given similar running conditions.
