Linkgage- design and send out for CNC

[Lotus54]

I have a couple modern OSSA Explorers- these are trials bikes with a seat and additional fuel. Same as the trials versions, with all the same features/drawbacks (depending on use of course).
I bought one of these new in 2014, ride the heck out of it. I managed to break the rear suspension linkage twice- then I bought a Titanium one a Czech guy was making. Well, those are no longer made.
So I designed a setup in Fusion (3d CAD), 3D printed to verify I got it right, then sent files to an outfit that CNC the part from Titanium. I changed the middle pivot to needle bearings instead of original teflon coated bushings- there was not room to change the others without some major work. I also added lubrication passages/ports so no need to dismantle to lube. Since the teflon bushings have no seals, just pushing a bunch of grease through can also push out most of the water/mud etc.

This was a pretty fun project, I learned a bunch made some goofups and have something that should work darn well.

Looks like a piece of jewelry. Are you sure that belongs on a dirt bike?

The Autozam Scrum (Japanese mini-truck) I’m rebuilding had a broken alternator mount. Only one place I found had replacements (used) and I won’t deal with that company again. Perhaps others had them, but I found I could have one much stouter made for less.
I desinged one, 3D printed to make sure I had it right and had the same outfit that did the OSSA linkage make it.

Came out great and $52.
