Thanks Rasmus! I have done a whole bunch of modeling, and I'm happy to share some of my 3d models with fellow motobrickers. Some of the parts I just used as a visual aid for design and are not super accurate, like the section of frame that I modeled. On that one I just took measurements with a tape measure and eyeballed some of the bend radii and angles.
On other parts, like the motronic unit, r1200gs led headlight, and lower triple clamp, I used a leica laser scanner to generate a point cloud and then used some fancy $30k/seat software(geologic design x) to make solid models, so they are pretty accurate. Here's a list of models that I have made, and brief description of each:
*Disclaimer*
My project is a 1996 k1100rs, I don't know how much stuff will carry over to other years and models. Most of the critical features(mounting holes and stuff) are accurate, but some aesthetic features may not be. These models have worked for my purposes, and I hope they work for your purposes, but please verify any critical dimensions on your particular project.
*Disclaimer*
Lower triple clamp-Laser scanned but I didn't finish modeling the steering stops because I am planning on doing adjustable eccentric stops on my custom clamps. The steering stem is an interference fit, and I haven't pressed out the steering stem yet to measure the actual bore diameter.
12 cell antigravity battery-It's pretty good, but the cases aren't manufactured to super tight tolerances so I would recommend verifying your individual battery measurements if your trying to fit it in a super tight space.
Motogadget M-unit v2-Mounting features and overall dimensions should be good, but I just eyeballed fillets and radii and such.
Motronic unit-Laser scanned, but the unit is just in a sheet metal chassis(not precisely manufactured), and I didn't bother to model the actual electrical connector.
R1200GS LED headlight-This thing is crazy! Everything is drafted, there aren't really any flat planes, and none of the features are symmetrical. I laser scanned it, but there are a few lofted and swept cut features that I didn't bother to model(strictly aesthetic). The vibration isolators are not part of the stock assembly, and I didn't bother modeling the lofted feature that they mount to. I could keep going on with more particulars, but won't unless someone really wants to know.
50 cal ammo box-I downloaded this assembly from grabcad, it seems pretty good though.
TC Bros enduro bars-These are modeled based on the dimensions on their website, though I took some measurements myself too.
Welded seat assembly/tragkorb rack-I designed this specifically for my project and tragkorb application. The vibration isolators are available from Mcmaster Carr, but I designed the rest of the mounting hardware as well as the cable gland. Each case should have a weight capacity of 60lbs. Functionally the tragkorbs are better lower, but I prefer them higher aesthetically so I built in some vertical adjustment into the mounting plates so that I can fine tune the height after I get the seat assembly welded up.
Bar risers-I designed these so that I could position the bars for better ergonomics while standing on the footpegs(for all of that theoretical post apocalyptic adventure riding I'm going to be doing), but they actually make the riding position very comfortable combined with the stock foot position(for all of that actual street riding that I will be doing). You will have to get longer cables though(LT cables might be long enough), and the rubber mounted bar clamps in the stock triple clamp feel too squishy with the additional leverage, so if using the stock triple clamps I would recommend removing those rubber bushings and coming up with a hard mounted modification.
Foot controls-I have literally spent hundreds of hours designing different versions, programing, and prototyping these. I made 4 individual work holding fixtures to machine them so far, and will have to design some more workholding for the brake pedal as well, which I have not machined yet. I am considering possibly doing a run of these for sale. BSK makes some really awesome rearsets for K-bikes, which are great for cafe racers, but there isn't really anything available for scrambler applications. The only issue is that that they would be expensive to make, both in material cost and machining time, and so even more expensive to buy. I don't know if it is a viable option yet, but in the meantime I would rather not share these particular models. I am happy to share information like the mounting hole locations and dimensions that I used though, so people can design their own if they feel so inclined.
I don't know they best way to share these files. I will probably save them as step files, drop them in a folder on google drive, and post a link to that folder in this thread. I'll plan on doing that sometime this weekend.
Hi
Thank you for the very elaborate reply :)
I was actually planning on modelling a "complete" K100 model in 3D CAD, both for the benefit of the community and builders in here, and also for my self to use in the making of my own custom '83 K100. I have been trawling the internet to find 3D models of the K bike, and so far I have only come up with a poor STL scan, see picture below. I was planning on using that as a reference to start out with, and then slowly build it up, part by part. Realistically i se this more as a collaborative task, since the brick (and motorcycles in general) consists of a lot of parts, and hence I will never be able to produce it all in my lifetime :)... In order not to hijack your thread, I should probably create a separate one for this purpose..
Your models should be a huge help to get this thing started! I see and understand your disclaimer :) I will use the dimensions with caution.. Mind I ask, what software are you using? I am modeling in SolidWorks 2017, kindly (unknowingly) provided by my company... My boss will think I am working late :clap:
I also completely respect your business plan for the footrests, go for it! :2thumbup:
I am looking forward to receive the link for your files..
Rasmus
