Hi all,

There are many references on the forum to RealOEM for identifying a bike for parts purposes, which is very useful. It gives month and year of production.

The one I found recently, http://bimmer.work, Not only gives model and month/year of production, but goes to very specific detail about actual date of production, colour, options included at build etc.

For my red bike that some will know, it comes up with:


1985 K100RT Red.  VIN 0028991K100RT  
 

Vehicle Identification Number	0028991

I've massaged the appearance in Word for clarity and deleted a second column in options which gives the German equivalent of the column shown, though some things aren't done into English.


Polizeiweiss = Police White

Nicht Gemeldet = Not Reported

Planglasspiegel = Plane glass mirror (presumably flat not convex)

Steckdose Fuer Zubehoer = Outlet for accessories



I had no idea mine was originally a Police bike, but the speedo isn't the usual Police bike type. I've been trying to figure out what BMW colour it is, but it doesn't seem to be any one that I could identify. Knowing it was originally white, now I know it could be anything.
My white one (or my white 0.9 of a bike) from RT was originally Baja Red, which is what I originally thought the bike detailed above was. 
Its all very confusing, however it is interesting to have the full detail.


Bill

You will see very fast if it's a police/administration bike!

Check the rear transmission number, 37/11 is for a normal non police bike. You will have 68PS power because of the U-Kat exhaust system.
The new bike have that mostly to.
I have changed my exhaust to a normal non U-Kat exhaust to get 75PS.

Check The number, if you chance The transmission, you will have more top Speed


Cheers

Hi espresso,
Mine has the 32/11 according to the final drive stamping. That seems to be what the book says it should be for an RT.

I've not seen any reference to 37/11, but perhaps the police specification in Germany was different to Australia. 

I've also never heard of a U-Kat exhaust. Can you tell me more about it?

Bill

I think 37/11 FD were made for K75 only. Correct me if I'm wrong.
Such a drive would not give you more "top speed" but lower top speed with greater power transmission to the rear wheel. Its a shorter gearing.

Hey Bill!
Ill try to explain, even so I'm missing some words in English but other colleges will help for sure.

There are basically three tips of exhaust.

1.) exhaust just a pipe without Kat (catalytic converter) 75hp
2.) exhaust with U-Kat ( catalytic converter) 68hp
3.) exhaust with U-Kat and Lamda probe! the K75 and K100 don't have that, all new bikes must have it.

I'm sure Kaptain Holister knows or can explain better.
I hope I wrote correct :-)

Cheers

Ah, catalytic converter I understand. 
I don't think any K100s in Oz had a catalytic converter. I don't know if the K1100 had it at any stage. 
The lambda sensor is essentially a sensor for residual oxygen in the exhaust, indicating the completeness of combustion and therefore correct fuel air mixture or not. The K100 fuel computer wasn't able to connect to a lambda sensor, nor make fuel adjustments based on sensor data. 
I know more about car take up rate of this technology than bikes, except that it was used on cars earlier than bikes. 
In Australia, cars were not required to run on unleaded fuel until 1986, and different manufacturers applied newer technology at different rates. I presume the same happened with bikes.  

Your writing isn't perfect English, but no problem to understand. It is a lot better than my German. I couldn't contribute to a German language forum, so We'll Done. Great to have you with us.

Bill

Well done Bill!
Thanks, my lack of technical term will have to improve.

Now I'm going to drink a nice whisky (Ardbeg Uigeadail) :-) to improve my English!

Cheers

I think that would improve your Scottish more than your English. 

Prost. 

Bill

Thanks Bill definitely one for my favourites.

Ah Espresso,

It appears we have another single malt connoisseur on the forum.  One of the little known secrets (not any more) of this forum is that Bert (CF) and I both have a love of Glenmorangie single malts.  If bad habits be known I have spent more on whisky recently than on my K75s. 

Recently I picked up a bottle of Ardbeg Corryvreckan at a very reasonable price with all the discounting that goes on at Christmas.  I went in with all intentions of adding a bottle of the Ooogie you speak of but the shelf was empty.  So settled on the Corryvreckan instead.  A great buy and one to stash away, as I believe they are limited to 5,000 bottles worldwide. 

I was very impressed with the availability of whisky (and grog) in French Supermarkets and must mention that Jude the Hooligan Pensioner has a taste for Aberlour 16 y.o.  The cost was about 36 Euros and a bottle here will set you back AUD140.

Here in Kweensland we are unable to buy alcohol at the supermarket unlike most of the rest of the civilised world. 

The thought of starting a whisky thread has been on my mind for a while now.  Any takers?

Cheers, Dave.

The only 37/11 rear drive I have come across is on a R100GSPD and from what the owner told me it was a little used option on them.
The K75 Authorities bikes were AFAIK ever only used here in South Australia by Police and St John Ambulance Paramedics, there are a few around but AFAIK ever only had the 32/10 rear drive.
I would hazard a guess and say that those were most likely a special order by German Authorities.

I would also be interested in getting a 37/11 drive if you have or know where I can get one.

My 1977 R75/7, bought new by me, had a 37/11 (3.36) final drive ratio. Good off the line but what a revver at highway speeds!

Up to 7/89, some std and K75C models had a 37/11...

Part number 33 11 1 451 345...I reckon it was for 18" rear wheel drum brake models only. There was an optional 34/11 (3.09) for disc brake rears, however.

Not to piss in anyone's soup here, but if you're not sure how to determine your ratio, and you have the stamping from your FD, simply divide the larger number by the smaller number for the ratio.

Example: 37 -/- 11 equals 3.36:1

              34 -/- 11 equals 3.09:1

              32 -/- 10 equals 3.20:1

The higher the ratio/number, the higher the revs at any given speed.

Ja Dave!
That's a nice drop, smoky good drop.
It makes you look different on the transmission :-) ratio

In Germany all police/administration bikes have a other drive ratio then the privat purchased bikes.
Some people change to a other transmission ratio or if you do a real good job than you change to Paralever from Monolever.

Cheers

quite surprised on first visit that New Zealand...which shares the world of grog in supermarkets ..  and some of our more civilised state and territory  areas ...like Canberra in the ACT (Australian Capitol Territory )  ....about time that the consortium of control freaks in the alcohol industry in the other states took notice that the exclusivity of sales of alcohol only (in licenced premises ) is a far outdated and archaic attempt at monopoly of an industry that should not demand so much attention that it is seeking (and demanding higher prices for the pleasure ) ....  hers a fact ...the aussie beer vb ...(Victoria biter )  is about 1/2 the price as sold at the supermarket in nz  (10 dollars nz = about $8.00 aussie at the time  ) as here in aussie   where its made   ......I say let there be equality for all to enjoy

and a nice drop of single malt at the right price would be great

Thread hijack!!!!

https://www.thewhiskyexchange.com/

I'm currently drinking a bottle of Laphroaig PX Cask (which, to be truthful, I'm not yet too sure about. Seems to need 2:1 whiskey/water ratio to get the flavour out). No, I didn't pay that price for it! - I got one duty-free on my last trip out of the country so it was quite a bit cheaper than that. I usually buy my whiskies from TWE though.

More hijacking

I managed, on my return to Motorcycling, to do a tour of Scotland - on a K of course and got to visit the Laphroig distillery.

In the interest's of safety the bikes were left at the b&b that day.

Maybe Dai's tipple were made in these.



I can highly recommend a visit to the Island but live the bike behind

I am sure I would enjoy those beverages, given the chance.  Whether I could ever pronounce their names is very much in doubt.

Interesting thread this, Jude is still waiting for the bottle that Dave promised her for doing his washing and letting him stay the night here rather than camping. Yes Dave it is cheap here but expensive enough for you to make the quick escape back to Aus without fulfilling your promises. 

using the link provided, I get to bimmer.work w/o http://

and it accepts the vin number's 7 last digits, but nothing happens other than it opens a fresh blank window.

suggestions?

This appears to be an update of the one I originally put up 4 years ago. The original doesn't given as complete information as it previously did, though it still works for part of the information. Trying it today, I found it doesn't work with my '93 K75 VIN. Guessing that it has to do with the later VIN type starting with WB1.

Duck's post gives all the information previously available, as well as working with the later VIN type, at least for my K75.

Thanks, Duck.
