Almost a year ago when I started to build my ducati 160, I scrounged up parts around the shop to make a bike to go with the motor. I never planned on this being it's final form, but since people seemed to like it so much I haven't changed it. Well, that's about to change.
A couple of days ago I pulled the engine for some more aggressive top end work, especially since I have resources available to me I didn't have previously to really get it right. While it's out, I started playing with the build a whole new frame idea again. My goal was to come up with a simple design that I could build without a frame jig, using only a tube roller and hand cutting all my notches. After a little playing around, I've done just that. My plan is to make everything other than the swing arm a single tube, so I can draw it out with the correct angle/radius, and just lay the parts on the drawing to confirm its correct. I've seen some builders to it this way with success.
Best I can tell with 2" .125 wall tubing, using the frame as a stressed member, I'll be good to go. I think the end result will be a bit lighter, but more importantly it will look awesome. I just ordered the tubing, plan is to screw around this weekend. In the mean time I'm open to suggestions, especially on the rear monoshock, front end, and wheels. I'm really trying to keep this lightweight, and I'm digging the idea of a supermotoish style.
Here's a very crude sketch of what my initial idea is.
