I've seen images of completed ones of these bikes around the web. As cool as I think they look- very out there, a great new school design (originality is awesome!)... They look horribly uncomfortable. Like, couldn't ride the thing for a half mile, even as a 'bar hopper'

Ok. progress has been a little slow due to finances. I sold my drift trike now and have ordered more parts. I have managed to get the new axle, axle adjusters and tail lights installed though

J wright how did you reinforce your backbone to mate up with the new rear? I'm planning something similar on a kz440, but I don't want it coming apart on the highway.

Thanks!

Thanks!

I welded 1/8x 1 1/2 angle to the inside where the new upper attaches, Didnt do anything to reinforce the bottom as it is already stout enough

Ok...

So its been awhile since any progress pics have been posted. this is due to me working alot of hours out of town. Now Im back in town and have more time to get this thing going. I have replaced the shift linkage with something I like a little better, got my pegs all figured out, got the seat and fox shock mounted up, rear fender and fork brace is mounted. Now working on headlight mount.

Still need to figure out...
Sprocket spacer
Rear axle spacers
Brakes
Wiring

Parts I drew and cnc plasma cut
