Yup, we decided to start with the older Ducati Monster Gen 1 trellis frame because:
a) it's widely accessible (used on Ducati bikes made from 1993-2007). Our team is based in SF, which is a distribution point for Ducati, meaning there's a glut of old generations available to tear apart, but they're easily accessible everywhere.
b) the mounting points on the engine mean that you can swap out for multiple types of engines, depending on your preference (620, 800, and you could possibly wedge a 748 in there if you really wanted to...)
c) the frame allows easy customization of the CAD files, based on style preference - you can make it shorter for a Bobber, longer for a Cafe Racer, change the rake and trail angles, etc. to fit your needs.
One of the women on the team who inspired this project is a track racer and finds it difficult to find bikes that work for her shorter stature, so this was a great use case for the customization.
Hey all, Madelynn here, community director at Fictiv and one of the folks on the Open-Source Motorcycle project.
Thanks for sharing this project and giving feedback, looks like the signup flow is causing some confusion, so we're in process of removing the need to enter your email to get access to the files.
I'm passionate about open source, as is our team, so we intended this project to be entirely open source and available to anyone to download, modify, and build upon the project. Documentation is still in the works, and I'm always looking for more folks to help out.
To remove vaporware concerns, you can download the files straight from here: http://bit.ly/2mU6l2y, and email me if you have any questions directly to me at madelynn@fictiv.com
If you want to talk motorcycles in general, I'm all ears there too. :)
Any plans to extend the open source work to electric motorcycles? There's a lot of motorcycle building talent over at https://endless-sphere.com/forums/, but I don't think anyone there is working on anything that's explicitly open source.
Hm, I don't see any issues with that, let me see what I can do. Feel free to email me if you have any other suggestions, on the files or documentation (which is being built out now), always could use another POV.
We originally wanted to keep it 10-15k, current files if produced as a 1-off may run higher, (closer to 20k). With interest, we want to batch produce these which keeps the cost lower. Cost will vary depending on obvious modifications and sources.
The download also has the full BOM, you can download those here: http://bit.ly/2mU6l2y
Thanks for responding. Without knowing much about Ducatis, what are the engine models that are available for this? Didn't see any jump out at first scan of the files.
PS you'll want to change your README.txt to README.md for Github's markdown formatter to read it correctly.
M600, M750, S2R 800. M900, later 748’s, and 916’s with a SSS (single-sided swing arm). Some other engines that require a SSS are also doable, but may need some additional modifications.
Thanks for the note on README, will adjust accordingly!
Some of the more complex parts are better suited for a 5-axis machine, but there are some great machine shops (including ones we work with)that specialize in this kind of work.
The goal of the project was to keep the cost to build at around $10-15k, which is cheaper than most custom jobs. This prototype ran closer to $20k, but with improvements on new versions, and the possibility of producing the parts in batch for interested parties, we can continue to keep the cost down.
Of course, cost can vary greatly depending on any additional modifications you might want to make.
Sorry yial, looks like the current email flow causes friction, it's being fixed now. Here's the files: http://bit.ly/2mU6l2y and feel free to reach out with any questions.
My mistake, I eventually did get an email with a link to the files --- I would rate it more under my own impatience coupled with the redirect to the fictiv main site.
OK. Here's one of those parts, the frame head top.[1] Needs at least 4-axis machining, maybe 5. I wonder how the work is held. All the modeled parts are frame components or brackets. No moving parts. It's a frame replacement. It's a nice piece of work, but the hype exceeds what's been done.
This reminds me of early marketing for the MakerBot Replicator, which was supposed to be able to "replicate itself". Except for the motors, leadscrews, bearings, extruder, and electronics. The few 3D printed parts were frame connectors.
The part you referenced was done on a 3-axis machine by one of our manufacturing partners. Like many expert machinists, he's got some ingenious methods for reducing set ups.
Appreciate that feedback. As someone who painfully remembers the early MakerBot marketing days, I feel the frustration.
Would be great to hear any suggestions on changes you'd make. Definitely want to make sure the copy is representative of the project.
We were inspired after we saw other motorcycle projects that beautiful, but didn't have any files available, or weren't even drivable. So we wanted to make a frame that was easily customizable and could be road-ready as fast as possible.
Can I pick your brain further? Feel free to email me at madelynn@fictiv.com. Happy to talk more about how the work is held, machines needed, etc. as well.
Yup, we followed OSH guidelines when building this project. As open source advocates here at Fictiv, we wanted the CAD to be downloadable and modifiable by anyone.
We realize that the current email signup flow causes some friction to getting the files, it's being remedied ASAP. In the meanwhile, here's the files: http://bit.ly/2mU6l2y
