The little Ducati Featherweight
« on: Dec 14, 2016, 09:01:54 »
So a little ducati motor just fell into my lap. That's my story and I'm sticking to it! I have very little idea what direction this is going in, other than the 2 words I have come to mind are cafe, and lightweight. Since this is a little guy (160 from a monza Jr) I'm kind if thinking why not try to make it an ultra lightweight bike, and see how "bare bones" I can get it and still have a safe functional machine. Perhaps build a frame from scratch,  which designed properly would allow for a nice sturdy structure but be a featherweight at the same time. Hey I like that, Ducati Featherweight, that's what I'll name this project. I needed another project like a hold in the head, oops!

I'm completely open to input here, especially in building the frame, so please by all means everyone throw up some ideas!

I have a shit ton of parts laying around, so once I have a frame this should go fast.

I'm on board, I have no help for you on the frame except if you want to title depending on where you are you'll want a donor frame for a vin #, get one that you can fit a good set of forks and a good wheel brake setup.

I'm working on a Monza Jr. right now as well. I have a later engine but the first series bodywork. Just pulled the engine to do the top end. Let me know if you need any frame measurements or a PDF of the service manual.

Thanks BarnBurner! I have the service manual, but I may take you up on measurements and maybe a few photos once I get going.

As far as building a frame goes this one would be reasonably easy to be honest!  If you don't want to build your own completely maybe an mx frame (steel) could be modified as they are single cylinder also.  Sounds like a fun project.

I think a CB160 frame would be awesome and this little engine would be perfect polished up and out front. Plus you could get a title for it easy

Lol i have a titled 175 frame i was eyeing as a plan B. I'd  want a usd front end for it, length would be an issue.

Just looked, I have everything for a 175 roller, including some fork lowers I put a stupid amount of time into. In theory, I could flip the rear wheel around, remount the tire, then its just a matter of motor mounts and alignment. As far as the weight goal, I think I could manage to get it under 200 dry. Interesting.

Here's the frame I have sitting. I have a different front end on it now but after looking at it, with a little chop chop that may do!
