Hi guys, we just started a project precisely one month ago. The results look good, so I thought maybe it is helpful for the community to see it. Usually we are building racing cars and customs, not bikes. Best regards and I hope to have time to keep you posted.

Another Turbo :clap:
Tight quarters on the tranny for it, will you be adding an air to air cooler?
Any plans for fuel management?

My intention is to run a low pressure, like 0.4-0.6 max. The debitmetre of the bike should do the job of sending more fuel. If not, we can write a new chart on the ECU.
Regarding the intercooler : it is not a must, but yes, would be helpful. But to do not forget the fact that earlier turbo engines didn't have an intercooler at all. Maybe I could install an air /water intercooler, using the engine refrigerant. We will see :)
The idea of the turbo setup is not about the extra power, but about the specific noise of the BOV :) So, that's why I don't want more turbo pressure.

Low boost, you might refer to it as "Normalizing". Not much heat compressed into the air charge at those levels so yes, a cooler not important - in fact might hinder performance.
However, if it's the thrills and chills of a noisy, squawking BOV, then depending on valve chosen and turbo flow, you may not have enough blow off to make the noise. I find the sounds are cool but you can only roll on and off hard so many times when your bike is a daily rider. For "Show" - guess that's another matter.

You guys do good work Gabi. :clap:

The fuel cap. It is not an "aviation type", it is actually a Boeing 707 fuel cap. We are using some aircraft parts on this bike. For example, the uniballs used for the gear box' lever its also Boeing 707 parts.

The coolant reservoir. We modified an oil catch tank, as it was laying around :). We will fabricate some aluminum parts in order to fix it. Work in progress for designing it.

The fuel cap. It is not an "aviation type", it is actually a Boeing 707 fuel cap.
BMW has many of us convinced that water infiltrating the fuel tank from around the cap was probable, so a drain pipe was installed in the tank with a pipe inside the tank that has an inlet along the left perimeter of the cap flange and an outlet beneath the tank. I don't see that inlet accommodation being made on your cap assembly. It's a work of industrial art though. :2thumbup:
(http://www.motobrick.com/gallery/0/1601-071117075318.jpeg)
Do you think fuel cap drainage is just another example of BMW's unnecessary overbuilding, or have you designed something I haven't noticed?

Many thanks for the info. Actually yes, I designed an O-ring between the bmw fuel cell and the adaptor plate. The chances are zero for the water to get inside the tank. I also left some space between the fuel cap (inside of it) and the adaptor for the ventilating and anti vacuum purposes. I really didn't want any screws visible, that's why I designed it this way. And it's finished, btw :) (https://uploads.tapatalk-cdn.com/20171107/5727b3e7eed3b942b448bd939d336d00.jpg)(https://uploads.tapatalk-cdn.com/20171107/48e30dbb550ba821ec179ddddbaa5062.jpg)(https://uploads.tapatalk-cdn.com/20171107/432d185fb088ebe1eee838e69a5ca4f3.jpg)

Starting working on the custom triple clamps. Keeping the bmw trail and rack, including the bearings (of course we will replace it with new ones), but wider, in order to use the 6 pistons calipers and 320 mm disc brakes. Using Suzuki gsx-r shocks. (https://uploads.tapatalk-cdn.com/20171114/72319686b0bf067d425251ef8690d399.jpg)

And the million parts that form the headlight assembly. It is a tricky one :) It rotate around two bearings, kept in place by two uniball arms on each side. That way we will have 2 bikes in one : normal position, headlight. Second position, when the entire assembly is rotating 180 degrees, you have a racing plate number facing the road. With a switch that shut down the headlight, of course. I think that this approach is a first - at least I don't know any custom or standard bike to incorporate that feature :) (https://uploads.tapatalk-cdn.com/20171118/7e29901cfd9613a0301cf959d40d36f5.jpg)(https://uploads.tapatalk-cdn.com/20171118/0d6634fa360e01f00a7ede05d6b790d5.jpg)(https://uploads.tapatalk-cdn.com/20171118/627ef137f89ac5eaff452815400ebad9.jpg)(https://uploads.tapatalk-cdn.com/20171118/f2cf8c11520bb6649667569ca0ad1529.jpg)(https://uploads.tapatalk-cdn.com/20171118/8e1751c16970248bdea4b2b8c5364471.jpg)(https://uploads.tapatalk-cdn.com/20171118/171e955e39359cda8b902f1d9e7faf7c.jpg)(https://uploads.tapatalk-cdn.com/20171118/c556c30a741be2b451c52fd956e72705.jpg)(https://uploads.tapatalk-cdn.com/20171118/3bae3e03a62273515e589b672742be03.jpg)(https://uploads.tapatalk-cdn.com/20171118/19f850fff440f25c40e20a4e781da56f.jpg)

Hi Mechanik:
I have been following your posts with much interest, not that I want to change my bike, but to see what is out there. Great CAD and fabrication techniques.
I saw all those 2D parts cut from sheet/plate. I initially thought that they were cut with a laser. Then I saw the 1/4" aluminum plate.... Are those cut with a water jet?
Just curious.

Hi, thanks for your comments. All the parts are laser cut, except the 1/4" (you have good eyes :), that ones are CNC machined.

Hi, ref the led strip I'm reluctant a little bit. As it was already done by a lot of builders. Not that it's something wrong with it, but I feel we can do it differently, more like "outside the box" thinking. We will keep you posted :)

You're going all out on this project Gabi. Starting to look like one of the more extensive custom K-bike build that I've seen. :2thumbup:

I couldn't hold myself and to not put together the headlight assembly with the anodized parts. It is ready to be mounted on the custom cnc triple clamps, which will be done hopefully next week.

This is a huge amount of custom fabrications! What other fabrication processes are you using besides CNC Machining? (Water Jet, Lathes, etc.)

Hi, we are using laser cutting, mainly, as well as lathes and various types of cnc machines. But the most important resource is the Autocad. Not to understand that the cad programs are doing anything without the human input :) But you can save a huge amount of time designing the parts.

Two things bother me about an otherwise spectacular build. The top triple clamp looks scary. You are replacing a forged steel part with an aluminum part that has been pretty well carved away. If that thing fails at speed, the resulting crash will be instantaneous and awful.
Second, what looks to me to be a mount for the rear shock is again machined aluminum, and not robust enough to make me feel comfortable about it's life expectancy. As with the triple clamp, failure at speed will be painful.
Have you done any stress analysis on these parts to confirm that the designs are up to the task?

Thanks for your comments. I really appreciate the fact you are concerned about the bikers good health and I mention the following : the OEM bmw triple clamp is not forged steel, but 1980' technology aluminum. What we are using for the triple clamps is aircraft specs 7075 aluminum. A much better material quality. Yes, we did the math (actually not us, but the CAD we are using) and apparently the new clamps are about 80% more fatigue resistant than the original ones.
Second : the rear suspension is bolted on the chasis, at one end (through steel plates, reinforced), and to the transmission at the other end, using also steel plating and roller bearings. (if you are talking about the aluminum traction arm, this one is genuine Suzuki, using roller bearings at both ends. Hard to believe it will brake - and if so, the rear wheel will still be supported by the fully compressed shock and will not gona touch anything)
I don't know if I mentioned here : our business is not custom bikes but building racing cars (rally raid and off road). I'm not sure if the bike design is ok, but I'm pretty sure that what we are building /fabricating is not gona fall apart... As with the Dakar cars we built: I'm driving the bike (or the cars)! So I wanna be sure that ar least what we do is well done :)
But thank you for your concerns.

Glad to hear you have done your homework. A lot of custom builders are 95% artist, and 5% engineer. Looks like you have reversed that equation. Anyone who can build a successful Dakar rally car certainly knows what they are doing.

7075 aluminium. Good stuff, but please do not weld anything to it. The high alloy content makes it very susceptible to stress corrosion cracking once taken out of the T7xx temper at which it is supplied. I would not even bake the paint, but use catalyzed paint !

Thanks for the concerns. Actually there is nothing to be welded on the triple clamps, just pure cnc machining. The finishing will be anodizing, as the rest of the aluminum parts.
To have more info about what we are doing you are welcome to visit www.taifunoffroad.ro, our business website.
Here you have the triple clamps 7075 material :) (https://uploads.tapatalk-cdn.com/20171217/586b3ecb2d7c750ae157b83bbd32a19a.jpg)(https://uploads.tapatalk-cdn.com/20171217/0c64ed58a196e14fcedbb4c01f63a659.jpg)(https://uploads.tapatalk-cdn.com/20171217/07eac1c8f61d8ce667b1dcab0434bd75.jpg)

My friend, thanks for the nice words. But : it is not like that at all. None of us was born with the wrenches in the hand. None, for sure. It is just a matter of time, experience, will to learn (and the necessary time) and passion. It is not even a matter of money. Because if you are creative (and knowledgeable), you can come up with the right solutions for the proper amount of money. Just my 2 cents :)

Congratulations on getting the line from the bottom of the tank thru the seat/rear subframe correct! Few Cafe K's get that right (or even seem to try).
Still trying to comprehend the geometry on the rear suspension.
Also, is the exhaust not where the coils need to be?

Hey nice work - especially the machined items!
I found myself studying the rear suspension linkages with a concern for survivability and robustness ( due to the minimal, elegant strokes) but looks right up to the task.
Where's the turbo?
Going to revisit that at the next juncture?
Following with great interest.

Thanks my friend :) Regarding the turbo, I decided not to install one on this bike, but on the next one.
Regarding the suspension geometry, it is working flawlessly. And it is highly tunable. Depending on the proportions of the pivoting link, you can obtain a stiffer suspension without touching the spring preload. Also, you can have a different riding high, depending on the length of the pulling link (the one which is located below the shock absorber. Actually, this is a Formula 1 suspension geometry reinterpretation,it is not such a big deal :)

Sorry for not answering so far, I was really busy doing other custom stuff. The exact amount of money I spent so far, cash out of the pocket is 7281 eur. Plus 325 labor hours. I'm almost finishing the bike, but I still need about 4 working days - which I don't have...

I have to admit that I’m curious about the rear shock absorber specifications.
I have zero experience calculating spring pressures and such. Did you use a shock that is a ready-built part for a different machine? Or is it a custom unit?

Amazing build! one question though :)
Why did you choose to put the rigid part in the front, and the moving (triangle) in the back? It would seem to me the connection point in the front is a better fit given the rigid frame.
I've been planning something similar for my own BMW K75. Using most of the Yamaha Yzf R1 linkage, and a custom made frame mount. main difference i've been planning is (as mentioned above) to keep the moving parts close to the frame.

Hi,
There are rotating points at the both sides, there is no fix part on this system... Or maybe I didn't got the idea you want to say?

I mean placing the brackets like this:
(https://i.imgur.com/JUhSSjV.jpg)
In my opinion, most of the force would meet in the front, closest to the frame. my idea of the setup would give you room to weld a bigger/stronger bracket to the frame instead of having to resort to re-use the treads on the back wheel.
On the back the setup would be a bit simpler than your setup allowing for a simpler bracket that would distribute the force more evenly.
But since you've build your setup, i would love to hear your thoughts :)

PS: sorry for the small image.
Feel free to post another, larger image, Joel. It will be more helpful than your current submission and should be much less effort than designing and building successful a suspension system :2thumbup: .
-
@Laitch, i know i should have created a larger version :) i just did it quickly to show Gabi how i think the linkage system could also work. (simply switching it around).
When i get cracking on my own project (hopefully starting next month) i'll do my own work-log. just wanted to hear Gabi's thoughts on my idea since he has some experience before i do my own CAD drawings instead of a crappy photoshop mockup :)
-
(https://i.imgur.com/l2MsywC.jpg)
I upscaled my crappy mockup and highlighted the 4 key parts. in red the bracket that mounts to the rear wheel, and the linkage that mounts to the frame
In yellow the dogbone and suspension. i hope this makes it a bit better to see.
PS: Editing posts is disabled in this forum?
-
It will not gonna work, for sure I would say... :))) Check the forces : when the wheel will go up, the fixed part on the diff will push against the shock. Fine. But the push/pull rod will follow the movement, so will rotate the triangles, which in turn will try to extend the shock. Which means you will have a shock that will move forward and backward, without being compressed or depressed.

Regarding editing, you need to reach a certain post count but I don't know what that is. What I did was Preview my posts to correct them before submissions, but we all agree that accidents will happen.

@Gabi, Thanks for you reply. I did a simple test in 3D and almost directly saw your point :) i changed it a bit;

Please take into the consideration the fact that the fixed part on the diff is not moving up and down straight, but it's rotating, having the center point at the gear box main bolts (where the rear transmission is bolted to the gear box). That will change your drawings a bit.

As well as that. The rocker on the chassis side has to rotate and have bushings for the shock and linkage. The animation does not alow the linkages to rotate in the rocker. It would work your way and has been done before. Since the rocker is at a pivot point higher than the swingarm pivot the center of the wheel will travel in an ark so that it is constantly moving closer the the rocker pivot. The whole point of the rocket is to fix the ratio of movement so the shock actually compresses a distance enough to dampen the movement without having a crazy pressure setup. Hope this helps. :bmwsmile
