BMW K1200S Preview
BMW may be regarded as a relatively conservative company, but every ten to twenty years, they embark on a print violate revolutions, while making Max Fritz-The inventor of the BMW “Boxer” engine back in 1923 -, play in the grave. In the year 1983, the K series with the shock troops Boxer inline four “flying brick” mill. Ten years ago, the F650 is the first time a stem is not driving a BMW motorcycle. Of course, it is 2004 and again in the BMW.
K1200S which can be considered as the most revolutionary BMW since the first Boxer in 1923 shook the world at the Paris motor show. Only if you do not see, it’s got an across the frame in-line four engine to keep the radical architecture frame mated to the front of the real alternative en d. Before you accuse BMW of plagiarism (R1 is not difficult to spot as the engine layout), remember that BMW does not know how to do things their own, especially when it comes to four-stroke engine design. 1156 cc mill that is crammed with the F-1 technology and other innovations. BMW how they see this, K1200S is a great tool Supersport and horsepower is a top priority. According to Mark Braunsperg, leader of the project, there is no “flat” configuration engine power can be given a target, because of the limitations of downdraft angle possible. Cannot progress that the entire frame in the four supply the necessary flow of air intake performance, while providing a very low center of gravity, a sacred cow in the BMW since day one. To achieve the desired low CG, the engine canted 55 ° from the vertical, something that also allows the tube twin-spar frame to hover above the engine. A twin-frame the debate in the BMW? Yes, and now as per Honda CBR approach that slight spars depends on the machine to finish the set and in the “cage”.
On the front of the frame spars, a new front suspension system. This is based on the early 80’s invention patents by Norman Hossack. Being a Formula 1 engineers at the time of this light the United Kingdom have a swell idea turned twin A-arm suspension seat a racecar around 90 degrees, with the weapons, such as what the upright rear swingarm. Automotive Bearings allow the two types of front forks to move up and down, twist, and also for steering. The unique geometry of the “Duolever” suspension allows the frame will be much lower (down CG) and reduce the stress of food to spars. Handlebars that are mounted on a separate axis, with the steering inputs to the food through the fork scissors type linkage. Separate, from the wheel bearing play can be made much steeper than the fork’s rake. In theory, this should provide a kind of “power steering” effect. One WP bump shock absorption to handle the tasks and the front and rear shocks are fully electronically controlled. ESA system that allows switching between the three basic set-up, early and damping settings can be changed also. Rear suspension / swingarm is pretty much a mirror image of the new unit found in the hollow axis R1200GS.
Configuring a new machine may look familiar but have a closer view the details of the engine and you will see that the BMW started with blank pages. Bah the dry mix and a special chain & gear drive cam allows engineers to make very narrow bottom end. When coupled with a dry sump, this allows the engine to sit low enough problems without the permission of the land. Dry sump also reduce the internal power loss. By using the short rockers to activate valve, cylinder head dimensions have been reduced and are more visible, such as 600, the head of 1200cc. If you need proof of how far BMW engineers were willing to go with the vibrant design parameters and advanced technology, you only need to see including the 21 ° angle between the valves. With the compression ratio of 13:1 in the large, 79 mm bore only possible by using smart, bursting-sensing engine management system. Then there is a 1.33:1 bore / stroke ratio. And to think that the K series undersquare actually …
At the end of the day, it is not difficult to see where the next five years (!) Building went. BMW is not afraid to tread new ground while defining their view of the “Supersport” tool for the new millennium. You can only imagine how much work must have been developed into the back of the cage developed mass Hossack front end solution to be produced. The same for the dry sump engine. Yes, the BMW may have a staid image and patient but when they do decide to re-invent themselves, they do so wholeheartedly. May I take my hat off?
Road tests to write this new Beemer is one hell of homework. I have a lot of good things to say about this, where should I start? From a truly alternative front suspension that works so well? Or, maybe I’ll start with the engine that makes a beautiful German merchantable, while atomically strong belief in the 8000 RPM? On the other hand, may be fined from ergos that left me fresh after a 300 mile day sports golf? How’s laser tracking as 130mph on the autobahn sweepers? A hard task indeed. The most revolutionary BMW since 1923 is not perfect, but it flies in the ointment is smaller, the problem of pre-production.
My initial impressions are not good however. When we emerged from the new born in Bavaria meat, I do not wind we first find the near future. Classy launch event was held in a glass on the floor high tower in downtown Munich. Some of the naked K1200S ’stood there to be examined, all their secret is exposed. Yeah, it’s crammed full of innovative technology. However, the visual-technical impact does not come even close to the shock I felt when putting the pieces in the far-R1 in the Milan show. The new Beemer has no wild and vibrant component of the compression R1, a bike which shouted performance and left me groggy, all at the same time. Please see the look on the bottom of the naked K1200S, and you will see.
The K1200S is, visually speaking, a very long and low platform, almost lazy looking. Consider its sporty pretensions, the proportion of wrong view, although never intended to be the CBR-RR / GSXR / R1 / zx-10R beating race rep. The K1200S front end / headlight area awkwardly wide and the entire gift is a kind of sealed matters. The back half of the bike although Airy and light, very technical looking while the design language of the seat / rear light is almost organic. The result is plain syntax strange, ‘kinda too long in the middle. During dinner, my side Saturday David Robb, BMW chief of the American motorcycle design department and pestered him about the S ‘looks, but even he was educated explanation of the design direction can not change opinions. All the interesting tech bits hidden from the eye, while there is something familiar about the end result. I heard someone say Super Blackbird? That said, BMW designers who deserve pat on the back for some amazing details. The entire rear drive / swingarm deliver muscle-technical feel. Way back footpeg supports cross path with the sub-frame tubes is mighty interesting, while the right side of the rear wheel is in the top right of the MV Agusta design league. Mr Robb claims that the chosen design direction is defined as “high-tech athletic” only if you need to control everything.
I hope to get a better impression on the day after, in a more normal environment such as the BMW garage, without the dramatic lighting effects, but no. In Gray / Yellow color scheme the design somehow works, but the White / Blue scheme looks 1980’s insanity. Yes, BMW have a weird thing about making the device look sometimes, just to see tails of 7-series cars, or S-Carver 650. According to Mr. Robb, it’s a deliberate choice to differentiate them from the rest of the pack. Healthy sales mean they are not wrong. Cutting corners on quality wise some of the details does not help K1200S ‘case either. A Beemer’s rear brake fluid reservoir is tied with the right foot by two pop rivets? Black paint on the frame does not appear to shimmer and cheap, rather than high technology. General screw and bolt plating looks dull. I wonder how other MO-ridians akan rate this design.
To put me in the right mood, a deep purr emanates from the silencer, sexy and raw as the voice of the seasoned German porno star. There is no relation to the traditional sound of the BMW off we all know. A little blip of the throttle and the revs jump in a jiffy, hinting at the large German healthy horsies hiding down there. This is somewhat confusing, this is truly a Beemer? Blame sixty years old bath by Bavarian engine forward a bit ….
A buttery snick slides first gear in, yes, there is no large engine speed flywheel on this one, a few loops in the parking lot and if I was blindfolded, I’d swear there is a normal telescopic suspension in the workplace. Behavior is linear and surefooted; not have the odd Telelever slow speed of the present behavior. After a few more miles, I can certainly affirm that the K1200S requires zero adaptation time for the original front end. It’s very user friendly and mental switch quickly flips to “love”. It looks like I will have a very good day on this K. Design-induced skepticism loosens its grip and I can start enjoying function rather than form.
