In its layout, the straight-six featured in the Concept 6 follows the well-known straight-four in the K 1300 model series. This ensures not only a low centre of gravity but a good weight balance as well. Furthermore, the straight-six featured in the BMW Motorrad Concept 6 comes with dry sump lubrication.
The oil reservoir is provided by an oil tank integrated at the rear of the engine block. This avoids the need for a separate tank, again helping to make the entire power unit more compact and reduce weight to a minimum.
Output of the new six-cylinder will be in approximately the same range as on BMW’s 1.3-litre straight-four power units. Torque, on the other hand, is associated to that of the 1.6-liter engines. BMW Concept 6 therefore comes with 130 Nm of torque from just 2,000 rpm and at the same time revving up almost to 9,000 rpm.
Moreover, fuel consumption of this six-cylinder naturally equipped with a fully controlled catalytic converter is said to be lower than on a comparable four-cylinder under normal touring conditions.
As for its design, the Concept 6 follows the lines of a Cafe Racer, with its long and and short rear. Another design characteristic are the Split Face, typical for BMW Motorrad’s latest models, the six-chamber exhaust system complete with sidepipe and the intake ducts finished in a platinum look.
Other details such as the instrument panel intentionally kept in minimalist design completes the model’s look. While a digital display shows the road speed, there is intentionally no rev counter, which is replaced by a LED display shows the rider at all times how much torque is readily available whenever required.
