TECHNICAL MOTOBRICK WRENCHING In Remembrance of Inge K. => Project Custom Motobricks => Topic started by: cdrp on February 26, 2016, 06:25:00 PM

Hi, everybody, almost a year ago, I bought a K1, 1989, the bike was abandoned around 15 years ago, it was in a poor fairy good condition, so I decided to restore it, during the restoration process, I started to wonder, what if I turn it into a K1 Cafe Racer, never seen one before, could I keep the the bike's K1 ADN? I knew what the bike was and what it meant to BMW history, like someone said, will the German goods take revenge for mi acts if I do so? well, it is a rare bike, and I don't see my self riding in a red leather suit if you know what I mean,.. so, I tried to keep as much as possible the original K1 parts, like the foot pegs, original, but CNC re-machined, the color, " Schwartz und Gelb" (Black and yellow) which was also standard for the K1, original rear shock, but with the piggyback reservoir exposed, original handlebar and controls, the instrument cluster, which will be replaced soon, it is too big, the exhaust system, which a clean surgery was applied to open, all the guts removed, and replaced for a straight perforated inside pipe, and shortened for better looks and sound, a new aluminum + leather seat, perfectly matched to the bike's style, Piaa 550 led lamps, and still, under construction is a very small bikini fairing...
Well here is the history if this adventure, I wish I was able to keep the K1 ADN and Soul, I hope you enjoy it as much as me, and the German goods don't come for me!

Sorry for the spelling, I meant Gods, not Goods... not native to english...
-
Well, congratulations on your beautiful build. But let me be the first to say you have committed a sacrilege, turning a rare historical K1 into an everyday cafe racer. Duh, why? Your build is excellent in the details, but it's still an ordinary, but expensive, cafe bike. What are you planning to do with the K-1 bits?
-
You have made a beautiful machine, pity about the choice of donor but at the end of the day regardless of who you upset ( and I'm sure there will be many) I's you'r bike to do with as you see fit. Say hi to all the fitter's of NGK leads when you get to hell, the god's are pissed. lol :grimreaper:
-
Sorry for the sacrilege, I couldn't help it, I needed to make it mine, something I like riding it, rather than keeping it on the garage.. "come look what a strange bike I got" most people don't know what a K1 is or what it represent, I knew what I was doing and I don't regret it, I really enjoyed working on the bike, all was home made, no external shop was involved, so it was not an expensive project, ... it is a rare but still a K1,... may be the only K1 cafe racer, never seen one before, and the most important ting, it is not the money or how much is worth, it is what expresses of your self, for me, I like to transform things, it is a way to communicate with others about who I am, I hope you forgive me, promise I will... do it again!
Regarding the parts, the top faring had an small accident on the left side, it is repaired but not vey well, can be fixed easily, most of the parts are in very good condition, paint is not original, if someone is interested, I like to sell them as a package, the complete fairing + ABS, (brain, sensors, pumps and wiring) one of the rear door pocket is re-made, not original, I can share individual photos of all parts if you like, when I bought the bike it had no front brake so ABS was not working, but I guess is OK
-
Not a big fan of cafe s but I do like this one :2thumbup: The donor choice is unfortunate but if the pieces removed are kept for a restoration later that might appease the gods somewhat :dunno2: I wonder if the visual accents could have been done on an 'ordinary K ?
-
Thanks for your comments, in the beginning, I was looking for a R series, but lucky, (...only for me I guess) I step into this one, I thought a lot about converting to a cafe racer, specially the value of the bike, but passion won over business, so it is a true K1, you can tell it is a true K1 by the foot pegs, more high and back than standards, the lift handle on the frame for the stand, the original yellow color on the transmission and wheels, so it is a K1 transformation, I called it the K1 Spyder ( spyder for BMW, spider for Ferrary) which for cars, it is meant for a roof-less or convertible, for a K1... naked ("K1 Spyder", it is on the expansion tank) .... and not everything is lost (for some) there are some damaged K1's that will benefit from original parts, which are scarce! ...or if I really repent, I can make it come bak, some welding and reassembly...mmm... may be not, I really like it this way!!!

Congrats on your build! Your attention to detail is really impressive - enjoy the bike:)

I have to admit that as much as I don't get excited about cafe jobs, I sort of find this one very attractive. The yellow and black color scheme highlights the mechanicals nicely, and the black helps to hide that unfortunate upswept line in the bottom rear of the fuel tank.
The seat looks like it might actually not be painful to sit on for longer than it takes to start the engine, and the way the back end of the seat cushion follows the line of the frame shows a good eye on the part of the builder as does the way the line of the top of the tank flows into the tail cowling. And somehow, even the stock instrument cluster looks like it belongs there.
The workmanship in all the fabricated parts is flawless as is their design.
All in all, even considering it was done to a K1, let me give a hearty "Well Done!" on this bike.
-
Congratulations. You took the one K bike that has actual value as a collectible (maybe not to you -- but it's true) and turned it into a bundle of cliches that no one but you will ever want to own. So, enjoy. And please make an effort to find a good home for the K1 tupperware.

I for one love the look. I thought the colors would clash. I admit I am choosing Gold, Black and Red as my colors (German flag), I hope to do as good of a job as you.
I think a well done cafe build is worth alot more than a standard OEM bike.
I want to take that idea for the gauges on the side... haha
By the way, how did you get around the Mass Airflow Meter by having induvidual air filters on the intake? I would love to have that look!!!
different ecu... motronic
**Oh and I was also looking at a K1 in my area before I settled on my k100** (being a K1 wouldn't have changed anything)
-
I need an air intake manifold for my K1. It plugs into the bottom of the air filter box.
I need part # 11, 3 and 10

You should post this in the classifieds section, not take over the OPs thread.
-
It is posted in the classified section. It was suggested that I come to this thread for the part.
-
Hi Donmystic, I am trying to sell everything as a package, but Let me think about it, I will contact you later,
-
Ok thank you
Don
-
I will publish all the parts in the "parts section"!!!
-
Amazing build quality, and attention to detail. Gauges and switches/controls are always a difficult bit to minimize or replace on a K. I admit I'm fond of the original 80's futuristic styling, but I appreciate that you went all the way with your vision.
-
Thanks for your comments!!! I hope it inspires you!!! , I am changing the gauges, I like them, but are to big, and installing a vey small fairing, photos coming soon....
-
Lovely build! Though I'm on the fence as I love both K1's and Kafe racers, you have made it yours and to a great build quality, so it looks brilliant.
What did you use for the coolant reservoir? The placement and visuals of it look fantastic.
(http://www.motobrick.com/index.php?action=dlattach;topic=7930.0;attach=13843;image)
If you made it would you mind sharing your wizardry on how you did it, that would be amazing.
-
Hi Bridge, thanks for your comments, regarding expansion thank, I made it from leftovers from my shop, it is a pice of 3" stainless sanitary tubbing, laser cut base, and a clear polycarbonate round lens with a "O" ring, the light comes from a blue LED inside the thank, on top is Tig welded a pice of 1" tubbing with a cover and two pneumatic connectors, in one the hose is troug, so it reaches under the coolant level and the other is a vent, also where the LED wires go, it works perfect and at night it looks radioactive!!!
-
Clever piece of ingenuity cdrp! I'll have to think of a way to try and replicate that as close as possible.
Amazing idea for the LED!
-
Finally after a lot of electronics and wiring, the new instrument cluster for the K1 is working!!!, I used the original speedometer amplifier and the original gear indicator, (this is a good link for the gear indicator, https://www.youtube.com/watch?v=P7bYGA2gnLA, how to convert it to a Led display), and a couple of burnt zener diodes and transistors, it is working, thanks to all of you that posted the required information, it really helped!!! I hope you like it, looks racer!!!
-
Looking good! Thanks for the clear profile photos.
-
Nicely done ! After all the other detail tou had to do it
-
Thanks!!!! [emoji106]

I'm still not quite for chopping up a K1 but your attention to detail is excellent. That gauge cluster is sweet

I'll let the purists attack you for your sacrilege, but have to reiterate what a wonderful job you did with this build -- your creativity and attention to detail is fantastic! There are so many small details and the big one's really stand out. Curious, how long did this project take you?
-
You know, Laitch, just when I think you have slipped from us with that Alzheimer's thingy, you come roaring back........ Lourdes Grobet?? I loved that Acapulco "Royals" song, but I'll bet she's an ugly bitch under that wrestling mask. What's she got to do with K-bike pitchers, anyway?
-
Very nice install of the gauges. :2thumbup:
They are by Speedhut, right? I put a pair of those on one of my Moto Guzzis. I used 80mm O-rings on top of the dash to cushion them a little. For future reference, you can get those buttons on the faces as remote buttons instead - just a simple plug on the back and then you can put the buttons wherever you want instead of having them go through the face of the gauges.
-
Yes, they are from Speedhut, I have not waterproofed them yet, I may try some engine silicon for gaskets, to keep it thin, thanks for your comments!!!

Regarding the project, I am making a very small fairing for the gauges and headlights, but I haven't got the rift measures.... Still in progress... May thanks for your encouraging comments!!!

CDRP, you have produced a beautifully detailed bike, and you deserve respect for your achievement.........The creativity and attention to detail is outstanding. No disrespect to your bike or you............but to sacrifice a fine specimen of a K1 which deserved restoration is a lost opportunity, financially and creatively. Any K100 garage bike could have received the benificence of your talent. You surely must be a professional to have accomplished such an excellent build,no?
-
Well, TrueAce, about your comment, I agree and not agree, a standard K100 will be that, standard, or a wannabe, a K1... well it is a K1, (very controversial K1), and yes, sometimes I question myself about what if?.... But past is past, .... I am not a professional builder, It's more passion than anything, and the bike came to me by accident, I tough a lot about restoring it, but again, the urge of creation and modifying won overall, I appreciate all your comments, in favor or against!!!

I respect your decision,and applaud your willingness to respond in a straight-forward manner to all comments, and admire the skill your build reflects. Congratulations on your very professional presentation of the BMW K1.

Fantastic build and individual expression of a clean cafe. I have no problem with using the K1, it was not the last one on earth, your bike, your vision , your rules. Enjoy the hell out of it.

Great improvement over the fugly BMW K1 original.
BMW designers Hans Muth, ex-chief of styling for BMW got it right with the early 1980's Suzuki Katanas, but BMW failed horribly with the K1 body work.
When people use the word " hate " to describe something, it sings loudly.
They should have kept Hans on.....
-
I love the original K1. I am purist.
I also LOVE and respect your K1 cafe. I am envious and want one.
Please contact me when you want to sell it, OR if you would do a similar build for me, SERIOUSLY!
Peter Frechie, easy enough to find near Phila Pa
-
Amazing job sir! Can we get a close up pic of the gas cap? I also love your radiator overflow tank. If you want a replacement for the chunky stock footpeg, Rizoma adapter and footpeg should fit the stock K1 bracket. It looks like the same dimensions as the K75/100. That's what I have on my K75.
-
Reopropf, regarding selling my bike, not now, but I will let you know if the time comes, regarding a build, I am kind of complicated right now but may be next year?
Duckytran, regarding the foot-pegs, the K1 came with the foot-pegs further up and back, different than any the other "K", a more sport approach, so I decided to CNC machine the original foot-pegs, (holes and removing the passenger foot-pegs) so the bike kept the original ADN as much as possible,
Many Thanks for you comments!!!
-
The gas cap is the original, brushed, some screws and a seat post quick release from a bicycle instead of a key,

Your creation is very original indeed. I'm curious as to how it's latch on inside with the bicycle seat post thingy.
-
That exceeds clever! You are not a garage hobby builder! When you first introduced us to your build, I was shocked at using a K-1. Your response then and since has shown that you are a class act, and so is your build. Now tell us how to give you the most sincere flattery........imitation! I have been playing with keyless cap ideas for my K-Badness, now I want to copy! :2thumbup:
-
Thanks for your comments, I really enjoy this stuff, to install the quick release, It is easy, take the key drum, remove the metal slots for the key, drill a hole, tap the hole to the thread size of the quick release, glue it with epoxy, assembly, you are done, you can buy the quick release from eBay from 3 dollars, many colors.... Just get the right pressure so when you open it you can turn the QR to opinion the cap like you do with the key,.... And again thanks for your comments!!!! You make me feel like a pro!!!!

That's brilliant, conceptualizing that would work in the first place. Very clever. I'm gonna try that on my gas cap. Thanks for sharing.

Yes +1
My fix was very amateurish.The bare minimum,even.

I did a cap before with an aluminum knob, eliminates the need for a screwdriver. The key top is cut done and deployed into the knob. What I'd really like is a aluminum quick release gas cap, like old British style, but I have never found on the diameter of a K tank opening. Let's have a "Innovative Gas Cap" review of everybody's innovations. :euro

Naw, it just means he was Fuck'n with cdrp's thread :hehehe

Cdrp, this is my first posting, I've been looking at a lot builds to get ideas for my K project and this has fired my inspiration 10 fold. Attention to detail does it for me. I'll look for a K1 :yow only joking lads, but I would if I found a rough one. Thanks for this inspirational post. Regards Jez.

Hi
I am busy doing the "opposite" you did, I am taking a bike back to red and yellow after if had a full respray to blue done 21 years ago.

Do you have any photo's of the inside of the main fairing, trying to figure out if it should be red or black?
Assume you have none of the parts left of this bike?

Hi, 2beAlive the inside of the faring is black, but I don't know if it was original like that, I almost positive of that, and yes, I have the complete set if you are interested, (http://uploads.tapatalk-cdn.com/20161007/db435941d882af6186e9d61397c723fd.jpg)(http://uploads.tapatalk-cdn.com/20161007/2019a4e44ae6420afdecb9cd095c7c69.jpg)

Hi
Great build
What did you do to strip the filler cap. Did you use paint stripper or hit it with a wire brush or something?

Hi, I use paint stripper and after I use a 3M polishing fiver, not sandpaper, it gives a smother finish,

"K1 Spyder", it is on the expansion tank
Where did you get that expansion tank? I'm looking for something similar for my K75...
-
I made one for my Cafe Racer from a piece of plastic drain pipe. Sprayed it silver and glued in a blue plexiglass window at one end. It looks similar to this project, but is a cheap option of course.[img][img]
