Many thanks Euro - I've been to your site before to have a look - and in the future I may be interested in the Mikunis.

Its interesting to hear what other people have done with their bikes!!!

Hi Nick,

just a quick peice of information: K-Bike forks are 41.4 mm, whereas the Showa fork used in the R 100R is 41 mm, which means that the R 100R fork yokes will fit into the R 65 steering head without any problems and they will accept the SV 650 fork legs.

greetings

Alfons

From model year '92 onward, the K fork tube was the same part as the R100R: 41mm. Early K had Sach (I think) forks, 4V K had Marzocchi, and late K75 had 41mm Showa (like the R). Only matters if you're mixing and matching, though.

Hi Anton & Nick,

it's established now: 2 V K 100 and K 75: Sachs forks (made in Germany) with 41.4 mm
late K 75 (from 1992 on) Showa forks (made in Japan) with 41 mm

4V K 100/K 1100 Marzochi (made in Italy) with 41.7 mm

here is a pic of my monolever airhead with a K 100 front end:



Greetings from Germany

Alfons

Thank you so much for clarifying this info for us Alfons and thanks again for the picture - I won't show it to my wife who is adamant I go for spoked wheels, not polished cast!!!

(I quietened her concerns by saying the NEXT project will have spoked wheels. I have a nice black eye now!!!)

1992 on K75 triple tree hey? no worries.

also, a 3 or 3.5in wide K75/K1100 rear wheel.

The bike should be here tomorrow, then pics to come. Its in a sorry state, so this will take some work!

Alfons, I'm interested in your adaptation of the dual exhaust: stock monolever slightly upswept? What kind of monolever is it anyways: street R80 or G/S? Got a website with more pics?

Sorry for the hijack.

Stephen

Hi Stephen,


it is a monolever which has undergone serious modification: I purchased it two years ago in a very sorry state: It had been sitting in a shed near the seaside, and the alloy parts looked awful. So I gave the old lady a thorough cleaning, and while doing so I noticed that the bike had been composed from various airhead types. The frame is the monolever type with the brackets for footpegs and exhausts on both sides, but the swingarm is the R 80 ST type, so that the German Fallert company (who transformed this bike), had to weld the R 80ST damper bracket onto the mono frame.
The exhaust system combines two different BMW systems: the downpipes are 38 mm with two crossover pipes (1981 to 1984 R 100) which carry the standard monolever silencers - nice throaty sound without the collector box. To make the silencer fit the pipes adapters were made.
Wheels are 2.5 x 17 (front wheel) and 3.5 x 18. The fairing is a Fallert-made type whose shape was taken from the K-bikes, and the engine is a 980 cc with high-compression pistons, 324 cam and 38mm Dellorto carbs. The previous owner gave me a dyna chart claiming about 78 hp.
It is a nice ride for an ageing gentleman like me!

greetings

Alfons

Well I came home from work tonight, and my new R65 had been delivered!!

No pics - too dark - I now have three BMW's sitting in the backyard, wife is kindanottoopissedoffbutwonderingwheniwillgetridofo ne!!!!

If you know what I mean!!

First glance, its not too bad - single disk front end with cast alloy rims. Front end has no notchiness - moves ok...Triple clamp looks a little worse for wear, luckily I have a spare if i decide to keep the front end.

Wife is pushing me to go with spokes and alloy rims....I'm in two minds at the moment.

Need to finish my other project - K1100R naked bike - and then I'm into this, with parts arriving via eBay...

AND my weekend is blown, have to work on a project at work all weekend long...sheesh.

Oh well - the pay rise next monday makes up for it!!

Pics soon!

On the subject of wheels, I got mine back from being straightened today.

Next week they are off to get blast cleaned and powder coated.





Cheers

John

Is that a 19" front wheel.

If it was the 18" it was fine. see link below

They were the recalled snowflake wheels.

They should have extra webbing

Looks good John, I have the same wheels, and I think the front end is fitted for two front disks, but only one fitted??

I'll take some pics on the weekend and post up.

Then the dismantling, scratching head and going "oh shit what have i gotten myself into!" will begin.

but only for about 20 mins because i have to work this weekend.

Thanks for the head's up Pezz, I didn't have a clue that there might have been an issue with the wheels, other than the fundamental lack of "roundness".

The bike is definitely an R65 and does not, to my untrained eye, appear to be a frankenbeemer, so I'm pretty sure it is the original 18" rim.

However I'll check the wheel when I get home this evening

Nick ... I'm well ahead of you in the "oh shit what have i gotten myself into!" department, but admit it. You love it really ...

Have a good 'un

John

You're right John!
