Hey does anyone know if the final drive and shaft assemblies from other newer models will fit the K11, if you take into account the re-engineering of the suspension?

That's kind of an odd question. If you need to re-engineer the suspension then it didn't fit.
I think you'd need to have the parts in hand in order to answer that question.
And by the time you've got it figured out and done you'd probably be better off monetarily just buying a newer model. K1200RS prices, at least in the US, have come way down lately.
And why mess with perfection in the first place?

Well, if I were to build my own frame it wouldn't matter about re-engineering the suspension, I'd just build my frame to suit the suspension design available. I suppose my question is rather could I take the rear end of a newer bike and bolt it into my k11 gear box, or won't it fit?
As misguided as I am, if it was perfect I wouldn't have a buring desire to change it.

Actually I don't think there is anything wrong with BMW's design, their engineers know way more about what their doing than I. I just like to interfere is all.

Nope....won't work....at least not with out major fabrication and as already pointed out the cost would out weight the cost of a newer bike. So unless you've got unlimited funds to throw away......WHY

Hi Splund...
ReL ""their engineers know way more about what their doing than I""
... wow, I would never make that assumption, and neither would anyone who owns or has ever owned an "airhead" ( pre '85 Boxers ).. I have never known a design firm ( ie; BMW) that has had, an still does have, so much trouble coming up with a reliable, trouble-free, positive action Side Stand ! BMW design of side-stands over the last 60 years is, and remains, woeful ! Dont give them more credit than they deserve. (( ie: if something as simple as the side stand design sucks, what about the rest of the machine ?? )
Best regards...........// Ernie in NH ( a very happy K1100 rider )

Ernie has his doubts;

Ok Ok, while it may be true that perfection is a hard mistress to satisfy, we don't need to throw the baby out with the bathwater.
My first big bike was a R69s, sidestand, no problem, the bike never let me down except where I had, as a teen, done wonky repairs or adjustments.
Now I have an R65LS and the sidestand, works fine, is small and elegant and I could not ask for a better part, in fact the whole bike is 'sweet'.
On our K11OG forum, we just about all have BMWs of mainly one variety, I too am here as a way of easing myself into a K bike. 
Why?
Because we are all silly egotists? Nope..... but because of relative quality.
Fact is, there are so many vintage and newer BMWs around because of relatively, good design, quality metallurgy, good access to spares, and overall relative 'sweetness' etc.
Oddly, I noticed on my mate's K1200R, that it had the identical, small, elegant sidestand design of my 84 R65LS. He never noticed a problem.
Quality does endure and as things endure, they will get older and relatively more side issues will appear as a result of aging, mileage, long usage, damage etc
The other thing is, technology and many other things, are often a compromise and cannot conform to the usage parameters of individual requirements.
Maybe nothing is perfect except for the notion of perfection
Anyways, when I land my K, I will be looking to attending to known issues, good thorough maintenance and proactive services and enjoying greatly, the careful thought and relative genius which I have come to appreciate in the bikes.
So take it easy and thanks so much for the education and diversity you all of the K11OG site have afforded me.... |

Hi Merlin....
I've submitted your "R bike Side Stand" comment to the Guiness Book of Records under the heading of "Rare-est Occurances".
Best regards..... // Ernie in NH [/b][/i]

Thanks mate, and when I get my K, I will fix the sidestand so that it conforms to the relative perfection that I demand
All the very best and thank you.  |

Well, more than a year has passed since I posted my question and its amazing how varied the answers are. In any case I thought it listen to the sage some gurus and not mess with perfection. Well, not materially significant.
Thanks for the advice.

Sounds sane.
If you wanted to improve the ride you could upgrade the rear monoshock as these do get tired and are probably re buildable.
There is lots of discussion on rear suspension and tyres and they do make quite some difference.
The is even a UK mob who are making a special rear suspension for the bike. If you search under Realm shocks I think you will find info.
All the best with it and safe rides |

Hi,
Sorry I discover the post now. I've been thinking of the same thing for a white: a K1200 suspension on a K11.
First you cannot fit a K12RS drive shaft on your K11 because it is longer (the K12LT is even longer I think), so you'd have to change the swing arm too, which means you have to adapt the front part of the swingarm to the K11 gearbox, and attach the suspension to the frame.
One would even want to adapt a K12RS gearbox to have a 6th gear, but it won't fit as is. I know some people even adapted a K12 engine to a K1 or K11, but at that point you may want to buy a K12RS which has a better frame and better front suspension and adapt a K11 fairing to it...

The K12rs has a backbone frame of ali, onto which the David Robb designed fairing fits snugly with determinded good looks and an airflow to match.
Except for the redesigned but essentially the same (K41) motor, the K12rs is altogether a different bike, although there are striking similarities to the K11rs of course. In a sense the K12rs was a transition bike towards the second generation of K bikes.
The K12rs motor is a stroked version of the K11, so it has even more torgue.
The telelever front suspension introduces swing arm monoshock front suspension, the pivot point of the front swing arm being only about a foot apart from the pivot point of the paralever. This introduces quite a diferent ride dynamic, very sensitive to the road and luxurious in the sweepers.
The heat issues are designed away with the frame blocking all hot airflow aft of the motor block and the twin radiators scooping air well off to either side of the bike.
Although there is a forward mounted oil cooler, the bike is only marginally cooled for city traffic and really is only comfortable when moving, but very little heat reaches the rider.
I am putting a water wetter, glycol free coolant in the K12 cooling system, aiding dynamic cooling, as I live in the sub tropics where frost is not an issue.
Gently ridden the K12rs will return a good mpg at 5ltrs per 100km or nearly 50 mpg.
The K12rs is a superlative all rounder and quite tame and manageable on dirt and gravel roads as well as cruising effortlessly two up and well over the ton on the freeway.
The only upgrade was in 2002 I think and the GT version (04-06) is a slightly cosmetically altered K12 RS with cruise control, heated grips n seat, slightly larger windshield, more upright sitting bars and weather lips on the fairing tips.
Wishing you all well from sunny n warm downunder oz

Number Six, the free man asks;
| Quote: | | What is it exactly? |
Zee fatherland is pretty good at engineering but sometimes other things like integration and appearance suffer;
I guess you would have heard of Hans Muth. the factory's first stylist of note in recent decades.
He was first let loose on the nuggety lil gem, the R65 Luxus Sport, which has a certain Darth Varda look, especially if painted black, which was not a factory option.
Hans went on to great success in redesigning virtually the whole range of bkes, but especially noted on R and K model road machines. He integrated components of style and airflow in a way which the market appreciated and which became industry practise worldwide.
Along came David Robb who used to work for Chrysler. Eventually he was given the job of upgrading the designs. He still used the germanic notion of 'form follows function' and not the reverse and insisted that the design statement should underlie functionality. Robb, from Boston, went to the same Pasadena Art Centre College to earn his transportation design degree as Ducati's Miguel Angel Galluzi.
The R1100RT the K1200RS, R1200C, R1100S and the K1200LT are all contributions of Robb's design team.
This team were good at 'arriving at this engaging blend of svelte organic curves and taut creases.' The coefficiency of drag has not been compromised, the numbers in this respect are low and the bikes are 'slippery' through the air, in a way that many bikes are simply not.
Thank you so very much David Robb, may you find a great lil niche somewhere that is good for you.
All the best from sunny downunder Oz |

So the "the David Robb designed fairing" is simply the standard K12RS fairing? You use complicated sentences man

You did say 'exactly' so I gave you the full bottle.
Also I think the final KRS is a wonderful machine that I count myself very very grateful to work on, own and ride.
All the best |

One costly word.
Have to try or even buy a K12RS, but here in France they are limited to 100 hp.
