Thread: BMW is blowing my mind!

    Thumbs up BMW is blowing my mind!

    From a long period of making civilized tourers and adventure bikes BMW has suddenly exploded into the most exciting and innovative maker of motorcycles on the planet! The HP2 has been shown here, and the new 1000RR discussed too, but check out what they introduced today at the big European bike show. Skip to the pictures below before trying to read the PR blurb - this thing rocks!

    Munich. Six-cylinder power units have always had particular appeal, offering not only supreme smoothness and refinement, but also superior power and performance as well as a truly emotional driving ? or, in this case, riding ? experience. A further point is that the typical sound of a straight-six almost like a turbine is absolutely incomparable, with straight-six power units at BMW having stood for fascinating engine technology in BMW cars for more than seven decades.
    Looking at motorcycles, inventive engineers have also tried time and again to offer the enthusiast the thrilling concept of a straight-six power unit. But while a few engines in straight-six configuration have indeed been fitted in motor?cycles both lengthwise and crosswise, the straight-six has never really made a genuine breakthrough neither on production models nor in motorcycle racing.

    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 centre of gravity. A further drawback was much higher engine weight usually setting off the benefits of extra engine power.

    The BMW Concept 6 now 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 new BMW straight-six will further expand the K-Series in the foreseeable future. The first model to be introduced will be an innovative and luxurious BMW touring machine. Reflecting the tradition of the BMW K-Series, this will of course be a genuine top-of-the-line product.

    Highly compact and dynamic six-cylinder.

    The starting point for this dynamic introduction of the straight-six in the new Concept 6 from BMW Motorrad is of course the extremely compact form and configuration of the engine. The power unit 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.

    High-tech lightweight construction in all areas serves to make the power unit relatively light from the outset, important components in this context being the two hollow-drilled camshafts and the very light connecting rods. The perfect compensation of masses ensured by the configuration and layout of the engine avoids the need for a balance shaft and its drive elements on the new straight-six, which again means lower weight and enhanced running smoothness.

    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 55o. 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. A further advantage is that the tilted engine provides extra space for the aerodynamically positioned intake manifold directly above the engine and allows ideal configuration of the frame profiles following the flow of power.

    The straight-six featured in the BMW Motorrad Concept 6 comes with dry sump lubrication. Apart from greater reliability even under extreme conditions, dry sump technology serves to keep the crankcase particularly low and flat, with the engine being fitted lower down and masses concentrated around the centre of gravity. Doing without an oil sump, the engine may be positioned far lower than on a conventional layout.

    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.

    Maximum supremacy in running refinement and performance.
    Designed and laid out as a straight-six, the engine also opens up new dimensions in motorcycling in terms of supremacy, power reserves, performance and running refinement.

    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, will be right at the top of the range, even in comparison with the largest motorcycle engines, such superior power and muscle coming inter alia from engine capacity of no less than 1.6 litres.

    The engine?s power and performance characteristics are equally impressive, offering 130 Nm or 96 lb-ft 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.

    Yeah, I caught it in my morning RSS scan, and meant to send it to you. I came home to find the email still up.

    Pretty crazy.

    I just realized, that the concept 6 shows heavy influence from the car side of the house. Several of the modern bikes have sported double kidneys, but this thing has the aero bits from the Vision ED concept - not to mention colors.

    Any update on that bober-esque concept (the successor to the 1200C)? I really liked it's style.

    Good call Rifle. And a beautiful design vocabulary. I'd like to see a new Z8 in this style. Would that be called "Future-retro"?

    I keep asking everyone I know in BMW world about it, and so far everyone just shrugs their shoulders. I do know that it got raved about by everyone in every market, and the idea was a massive hit. The flip side is it is more than a little complicated to make and deliver custom bikes, and isn't really something that BMW is set up to handle, so while the idea was a hit the logistical reality in this economy might well kill it stone dead.

    Also BMW are working hard to expand beyond the boxer, so there is a fair chance that it will simply get left behind as the new 4's & 6's like the one above come on line. I'm a boxer twin fan because I grew up on them, and my dad rode them too, but I wonder if the new generation of Jap & Italian bike fans have the same emotional connection to the boxer as we do. I'm feeling that the big twin could be nearing the end of its natural development, and that BMW don't want to be the prisoner of their past, but we could have said that about Porsche and the 911 when they launched the 928 and 944, and Harley when they introduced water cooled V-Rod motors. Heritage won both those battles against the odds, so maybe the boxer has a sporting chance!

    I'd settle for what appears to be a top hinged accelerator pedal.
