Stunning Concept 6!

BMW have revealed an enticing straight six concept that will further expand the K Series.

The BMW Concept 6 proves that a straight-six, benefiting from the most advanced construction and production technology, may offer not only unique prestige, but also a supreme standard of riding dynamics.

The BMW 'six' is approximately 100 mm or 4" slimmer than all former straight-six production engines and only a bit wider than a large capacity straight four with conventional technology.

The reduction in width is achieved in particular by the slightly over square bore/stroke ratio with relatively long stroke and very small gaps between cylinders. To achieve this very compact configuration with minimum width, the electrical ancillaries and their drive components are positioned behind the crankshaft in the open space above the transmission.

In its layout, the straight six featured in the Concept 6 follows the well known straight-four in the K 1300 model series, again coming with cylinders tilted to the front by 55. This ensures not only a low centre of gravity, but also very good weight balance as an element essential above all under sporting conditions for precise feeling and clear feedback from the front.

Output of the new six-cylinder will be in approximately the same range as on BMW's 1.3-litre straight four power units. The engine's power and performance characteristics are impressive, offering 130Nm of torque from just 2,000 rpm and at the same time revving up almost to 9,000 rpm - a dynamic potential quite unparalleled in the tourer segment. This alone qualifies the engine of the Concept 6 as the ideal power unit for a wide range of different motorcycles.
