if u r referring it to the S1000RRi think it will be about the same price as your CBR1000 lah.. they are pricing it to tapau the market segment around the world though it does not reflect the true value of the S1000 which they said should have been around Ducati 1198's price..
Six - the magic figure in motorcycle construction. BMW Motorrad presents the study Concept 6 at the EICMA.
6-cylinder engines have always been rather special in motorcycle construction. They are fascinating because of their supremacy and incomparable drivetrain comfort and offer not just maximum running smoothness but also performance figures which speak for themselves. The rider enjoys the characteristic, almost turbine-like sound of an in-line 6-cylinder: it is truly unsurpassed. In the automobile field, BMW has tradition of 6-cylinder engines going back more than seven decades.
Nonetheless: an engine like this in a motorcycle presents quite a challenge. Size, centre-of-gravity location and weight are all critical factors which can affect efficiency. But the study BMW Concept 6 shows impressively that this engine concept can be realised not only as a prestige bike but also with dynamic style thanks to state-of-the-art engineering and production methods. The K series is to be developed further within the foreseeable future with the new BMW 6-cylinder engine. The first serial production model will be a BMW touring model which is both innovative and luxurious: top of the line.
The basis for this highly dynamic realisation of a 6-cylinder engine in the form of BMW Motorrad's study Concept 6 is the extremely compact nature of the engine. It is around 100 mm narrower than all previous in-line 6-cylinder power units and only a little wider than a current large-volume 4-cylinder in-line engine. This narrow width was achieved in particular by means of a very lightly oversquare bore/stroke ratio with a relatively long stroke and very small distances between the cylinders. In order to realise the reduced width, the electrical auxiliary units and their drive gear are positioned behind the crankshaft in the free space above the gearbox. The relatively low weight of the engine unit is achieved by means of selective lightweight construction in all areas: for example with hollow-bore camshafts and very light connecting rods. A 6-cylinder engine does not require a balancing shaft, so this saves further weight.
In terms of layout the 6-cylinder - with its bucket tappets for low maintenance -is based on the familiar in-line 4-cylinder engine of the K 1300 series. Like the latter it has a cylinder bank which is tilted 55 degrees forward: a low centre of gravity and balanced weight distribution result from this - absolutely imperative for a precise ride feel and transparent feedback from the front section. The tilt of the engine also creates space for an aerodynamically optimised intake system directly above the engine, as well as enabling an ideal design of the frame profiles in line with the distribution of forces. A dry sump lubrication system provides not just increased operating reliability even under extreme conditions due to the lack of an oil sump but also enables a flatter construction of the crankcase and thus lower installation position of the engine with a concentration of masses close to the centre of gravity. The oil reservoir provides an integrated oil tank in the rear section of the engine housing. This means there is no need for a separate tank, which again has an advantageous effect on compactness and weight.
This engine definitely opens up a whole new dimension of motorcycling in terms of supremacy, power delivery and running smoothness. The output of the new 6-cylinder will be within the range of the BMW Motorrad 1.3 in-line 4-cylinder engines. However, its torque level will be in the very top class of large-volume motorcycle engines. It draws its power from a capacity of 1.6 litres, among other things. The performance characteristics are therefore highly impressive: even at low engine speeds from 2000 rpm torque of 130 Nm is available, and the highest engine speed of some 9000 rpm reveals a level of dynamic potential which is barely matched within the touring bike segment in particular. This configuration essentially qualifies the Concept 6 engine for a wide range of potential motorcycle concepts.
The 6-cylinder engine of Concept 6 also shows supremacy from an ecological and an economical point of view. Fitted with closed-loop catalytic converter technology, the fuel consumption of the 6-cylinder is below that of any comparable engine concept, assuming a touring-appropriate riding style. The use of E-Gas (ride by wire) provides various selectable ride modes for greater potential in terms of fuel consumption and riding dynamics.
With a thrilling design, the creators of Concept 6 wanted to convey the supremacy and dynamic performance of the machine in a very distinctive manner. Once again, this BMW Motorrad study reflects the attempt to develop more than just a motorcycle which has never existed in this form before.
The BMW Motorrad designers focused again not just on technological functions and quality but on the emotional component linking man and motorcycle. The motto here was: a motorcycle doesn't jut have to obey the laws of functionality but also has to arouse emotions in all sorts of ways. In short: people have to love it.
The design of Concept 6 focused on the powerful 6-cylinder in-line engine. Conceived as a mixture of classic and modern stylistic elements of motorcycle construction, Concept 6 takes up the formal style of the legendary café racers with a long front section and short rear. In powerful, muscular style, the body elements enclose the platinum-finished engine, displaying it with relish from all angles
There are particularly soft lines which organically integrate the engine on the one hand but also contrast powerfully with the sharply contoured front and rear section, generating tension and dynamism.
As a familiar design element in current BMW Motorrad models, the so-called 'split face' runs from the trim nose through the top of the fuel tank, which is made of carbon fibre and underscores Concept 6's high technological aspirations - thus creating an exciting contrast with the outer shell in aluminium and the white layers. The visual trisection created by the split face is reinforced by the LED headlamp which is integrated lengthwise at the front in pole form as well as a narrow LED rear light which runs up high into the seat.
The six-flow exhaust system with side pipes and the powerful presence of the platinum-coloured intake ports emphasise the powerful and supreme character of Concept 6. On the other hand, aerodynamic components such as the twin-tipped engine spoiler and air deflector elements borrowed from the new supersports bike S 1000 RR create a link between functionally conceived, visible technology and more gently shaped sections.
In terms of wheel control, Concept 6 has a light alloy bridge frame and Duolever and lightweight construction Paralever at front and rear respectively. The 17-inch HP forged wheels and the large brake system with 6-piston fixed caliper brakes at the rear contribute to the bike's sporty appearance and high technological aspirations.
Other details of Concept 6 include the minimalistically shaped but complete instrument panel. While there is a digital display which provides information on road speed as usual, no tachometer is included due to the large amount of power available. Instead there is an LED display which shows how much usable torque reserve is currently available to the rider.
