Title: 93 K75 "Fist of Fury"
Post by: duckytran on September 12, 2016, 04:03:38 PM
Hello fellow flying brickers,

I'm fresh to this forum and wish I had known about it a couple of years ago. Better late than never I suppose. I've been checking out all of these resto, resto-mod, and full cafe conversion projects on the Project K-Bikes section and I can't get enough of it. The level of details on the work and knowledge of K-Bikes are unparalleled. This global community is so friendly, open, and eager to help. I also love all of the witty comments.

I purchased this very clean 93 K75 (22k miles) on a whim from a co-worker who had too many bikes in his garage. This is after not riding for 20+ yrs (4 knee surgeries, marriage, 3 kids..blah, blah, blah). At first, the bike really didn't appeal to me given that I was a former crotch rocket rider (Ninja/CBR). So I googled images of k-bikes and saw a few cafe style conversions and I was sold on it. I took the bike home (without consulting with the wife first, figuring I'd beg for forgiveness later). I told her I was going to covert it and sell it for a profit. Well, 2 yrs and thousand of dollars later and the bike is still in my garage and I'm being reminded of my deceit ever so often. I love this bike to death as it has been part of me for the past 2 yrs. I've made so many changes to it that my wife said I have ADD design. I named it after my fav Bruce Lee movie. I figured every bike needs a badass name.

I was a little apprehensive on posting this at first since there's so many good and professional level builds on this forum. I'm not a builder or a mechanic. Just a trial and error kind of guy that take the plunge into things. My bike is a little rough around the edges and is not as totally clean as some of these other projects. My only goal in posting this is to solicit feedback/critique (good and bad) from this respected community. I have thick skin, so no worries!

Thank you for your time in reading this (perhaps too wordy) and for your comments.

Thank you all for your kind words. When I first started this project, no one was selling aftermarket parts for K-Bikes. Seems like they're getting chopped up left and right now. A few shops, mainly in EU, are now selling nice parts. BSK Speedworks, Unit Garage, and Cafe4Racers to name a few. I got my gas cap from Z17 Customs out of Moscow. I saw it on Instagram and contacted them. They don't sell parts online, but will sell you one directly.

Laitch,
I had you in mind when I wrote that part about loving all the witty comments :yes :2thumbup:

One of the nicer conversions :bmwsmile.  I like it...the only part that made me wince was the 22k odo.  The thing that is important is that you care for the bike.  PS, wife says similar things here :hehehe, oh, and the occasional midlife crisis comment!

You're too kind Mr. TrueAce. I'll try to add more color to this thread.

Thanks Mr. Mighty Gryphon. Luckily, I have a cousin who is a professional tailor. This is the first bag he ever made and it came out nicely. The material I actually used is convertible top vinyl fabric. It's durable and weather proof. I prefer not wear a big back pack when riding, so I needed a place to hold insurance paper, a few tools, and nick knacks.

I avoid riding at night, so I re-purpose these fork reflector pieces to add a little custom touch to the bike. One set is with leather and the other with aluminum. Both were laser engraved. I'm on the fence as to which one better match the bike aesthetic. Let me know what you think.
Title: Re: 93 K75 "Fist of Fury"
Post by: jakgieger on September 16, 2016, 09:06:00 AM
Both cool :bmwsmile.  Aluminum is definitely "louder".  It appears to me that the rest of the bike is "under-stated" modification.  Thus, I would choose the reflector.  I doubt BMW would approve the aluminum :hehehe

Some places where I've lived, a tag like that would attract vandals like an abandoned building. I can hear the "Oh yeah?" followed by the bike's hitting the pavement.

Are these prototype tags or the final versions? Their current appearance doesn't rise to the level of your other work on the bike. If you pursue this idea, consider taking the leather tag to a leatherworker and having the name carved into the leather tag, having a metal tag etched or a plastic tag manufactured by a 3-D printer.

Better yet might be to have your initials carved or worked onto a tag with a border of interlocking nunchaku.

Thanks for your insight guys. I don't think the folks in Austin are that maligned, but hell people are people. These were not meant as prototypes. I'm certainly not the first to do this, so I'll need to research other examples. The aluminum version is a little understated. Perhaps a brushed nickle finish would look better.

TrueAce,
Stage 1 was by far the most challenging since I was pretty much a fish out of water. I could have taken the bike down the street to the renown moto shop Revival Cycles, but that would mean taking out a home equity loan and sleeping on the couch  :nono . So, I just dove in and did what I was capable and solicit others for task such as welding and upholstery.
Front End:
- Got LED headlight and fork brackets. Wiring was straight forward.
- I was perplexed as to why BMW designed such a huge instrument cluster and put all of the electronic components inside. There was no such thing as a plug and play replacement at that time. I called some shops that sell cafe racer products and got "what the hell is a k-bike" response lol. So, I made a bracket that would lay the cluster down flatter and added a tube to hold the front blinkers. Called it good enough.
- It still looked weird to me, as you can see from the 1st pic of stage 1, for the huge cluster to lay on top of the headlight. I searched for something aftermarket to help hide it a bit without having to try and fabricate one from scratch. I found the fly screen from the Ducati Monster to be a good fit. Made a simple bracket that attached to the bottom of the cluster. Painted it black. 
- Relocated the ignition key to the rear. Just a simple metal tube housing to keep it in place.
- Added fork boots since I like that look rather naked forks.
- Got Renthal handlebar, but then switched to a set of Suzuki SV650 strap-ons with a 1.5" riser found on CL.
- The paint on the gas tank and radiator fairings was in great shape, so I left it alone. Added racing stripes by simply using automotive trim paint.
- Removed the paint to the front wheel fenders since it was rather chipped up.
- Got a set of bar end mirrors and the front half was done.

Back End:
- I lost a lot of sleep in trying to figure out what to do about the seat. I look extensively on the interweb for an aftermarket one. The ones that I like were too narrow, which would mean extensive reconfiguration of the rear subframe. I have no experience in metal fabrication or welding. Outsourcing that work would have been rather expensive.
- I took the path of least resistance and shorten the rear seat frame and reusing the original tail loop. Added a piece for the licence plate and tabs to hold the rear blinkers. Had a welder weld it together. To be honest, this section of the bike is not the cleanest for me. The tail loop doesn't really match the line of the seat pan. Perhaps stage 4 work will rectify that.
- I decided to try and design the seat myself as I felt it was one of the most important feature of the bike. If you don't get the seat right, everything else would just look pieced together. I tried to follow the lines and contour of the gas tank. Made a model out of cardboard. Seat pan was made from a piece of aluminum. Took it to an automotive upholsterer and got it made with high grade vinyl fabric. Added a BMW emblem. It's held in place with just 2 simple bolts in the rear.
- Got number plates as side panels.
- Replaced original exhaust with a Staintune one found on CL, which is much lighter.
- Removed the center stand to shed weight
- Bates style LED brake light. Rear wiring was straight forward too.
- Progressive 412 shock was fairly new, so I kept it.
- Both tires were pretty much brand new when I purchase the bike.
- Found a rear wheel hub cover on eBay

That's all she wrote for stage 1  :mm :bmwsmile !

More ADD design rearing its ugly head. I decided to try and cover up the gap between the seat pan and top frame using the same material as the left side panel, battery box, and front panel. If anything, I guess I'm being consistent with the material used. I haven't figured out how to attach it yet, but let me know what you think fellow brickers.

Your iterating in the right direction.Attachment should include anti chafe on the frame rails.ADD design is just normal.We have varying degrees of awareness including aesthetics.Anything else ends up being mediocre.Looking good.

Duckytran, great job on this bike. Unfortunately, for the future inventory of stock K-bikes, these machines really seem to lend themselves to this type of conversion. They have a great boxy industrial look to them. The engine is, clearly, the dominant feature. The only thing I would ask is have you considered removing the radiator cowling? It's a pretty cool look to see the rad simply exposed. It's a wonderful bike either way....but you might want to toy with that idea. Check the other conversions out where this has been done.

Cheers!

PS - tell your loving wife that you were only kidding when you said this was a spec project. Tell her the boys and girls on motobrick would look unfavourably on you reducing these beauties to a simple commodity to be traded! You've put your soul into this bike. How could you part with it? It's time to build the stable!!

Hi Kris,
I couldn't agree more that K-bikes are getting more popular for conversions. From perusing this forum and the K-100 forum, I think there are plenty of purists that will restore and keep K-bikes in their original form. It hasn't proliferated to the level of chopping compared to the R-Bikes that I can tell. I guess time will tell. As for the radiator cowling, I left it on because I felt it looked better than a fully exposed radiator. It also function to protect the radiator from rocks. Most of the conversions that I saw, the radiator cowling was either removed completely or modified. I guess I wanted to be a little different and leave some part of the K-bike in its original form.   

"You've put your soul into this bike. How could you part with it?" I couldn't have said this any better. The lovely wife and kids are slowly learning to live with this obsession of mine. But once in a while, they give me this  :musicboohoo:

Thanks for the feedback!

So, I picked up a radiator fender/cover off CL for cheap and decided to try hydrographic coating instead of paint or vinyl wrap. I also did the front wheel fenders and gas cap to match. A local shop did the work. An automotive clear coat was applied, so it will be durable and hopefully last pretty long. It came out pretty sweet I think.

Have a spare tank sitting in the garage for a few months and got the itch to do something with it. Actually, another post by Gurujimmy inspired me.


Anyway, it took forever to strip the original paint but I got it down to bare aluminum. Sanded the top and the rear sides to give it a brush aluminum finish. The top will have racing stripes with bare aluminum as will the rear sides. The rest of the tank will be Corvette red. It'll be done by this weekend.

Thanks James. The tank is complete now with 3 clear coats. My only dilemma is which gas cap to use. I also sanded down the original cap and gave it a brushed aluminum finish. The black one give it a little bit of a contrast while the original one blend in.

Personally I prefer the original with the brushed aluminium look...
double that, err ahh quadruple,  or  yea,  the original.........., with the brushed aluminium  finish! :2thumbup: love The  carbon fiber hydrographics on the cap, but the original fits the look better IMHO!

Thanks James. The tank is complete now with 3 clear coats. My only dilemma is which gas cap to use. I also sanded down the original cap and gave it a brushed aluminum finish. The black one give it a little bit of a contrast while the original one blend in.


Chime in Motobrickers!


Hey Bud,


Both filler cap options look great, I do tend to lean towards the brushed original.


Loving you work.

Motobrickers,


I have embarked on a new project. This time, it's an Airhead. I've always wanted one and have been searching for over a year now. I stumbled onto this one thru the same fella that sold me the K75. A neighbor of his is an eclectic Airhead collector. He bought a bunch of old Airheads to add to his motorcycle rental fleet. Come to find out, he couldn't get rental insurance for them. Long story short, he sold me this gem for $1800 (he took a loss of ~$1600). It's an 1981 R65 with ~55k miles. It's a clean and mechanically sound bike. This time around, I'm not going to chop it up. The modifications I'm going to do will be completely reversible. I've convinced the wife and kids to let me keep the K75 as I couldn't imagine to part way with it.


P.S. I have not found an Airhead forum as good as this one. If there's a good one out there, let me know.

When it comes to classic airheads, customizers of them might become desaparecidos unless they're on a generic customizer forum, or so it appears anyway.

Here's where I'm at with the R65 for those interested. The tank isn't completely fitted yet. Waiting on a bracket so I can lift the rear up a little.

Bro, what front fender is that? 


Also I'd redo the aluminum fork "plaques" by using a black base and engrave the lettering in silver.  Idk that leather is a great material choice that close to pavement and puddles.


Liking it so far....I too have the 2 project k75 cafe bike....been a little less add tho😁

The front fender on the K75 is the original fender trimmed down to the shape that I like. I then had it hydrographic dipped in a carbon fiber pattern. It's the poor man carbon fiber-ish fender I suppose.


Thanks for the suggestion on the fork plagues.


Start a build thread on your K75 projects. The community would like to see what you're doing to them.

I finally re-did the rear end, the K75 that is. Much cleaner now and match the lines of the seat pan. Will make a bracket to relocate the license plate to lower shock bolt. Thanks to RBM's help, I was able to sort out the LED conversion issue.

Both bikes look great. But concerning the K75.....what model Fox shock is that and is it compatible with a K100? Thanks, RV

Thanks RV. Below is the link to the shock. I worked with both ATVGalaxy and Fox technical support to make sure the spring rating is compatible with the K75. The length, which is 14" eye-eye should be compatible with both the K75 and K100. You just have to make sure they build it with a spring that can support the weight range of the K100. Let me know if this isn't clear. This is one of the cheapest option that I've found for an adjustable shock with a piggy back reservoir.

Quality work, ducky!  Great attention to details.  Gotta have at least one K to zip around town and country.  Wish I had room for one more.  Being much lighter it must handle nice.  What's good, there's so many of these bikes for sale, well within anyone's budget.

Thank you sir! Yes, it's much lighter and more agile now. However, it's still quite a heavy bike compared to modern ones. The K-bike is becoming a popular platform for conversions. Perhaps because it's still affordable compared to Airheads.
