How long is the lever?
Do you have reason to believe that it's from a motorcycle? It would seem to be short for something similar to the old Harley suicide shifters. And the cam lobe it moves (if I'm seeing it right) makes me think it's a hydraulic controller, which wouldn't be from a motorcycle (as far as I know).
Indian "jockey shifter" by the looks of it. aka "Suicide shifter" or Jockey shift with suicide clutch. I think it was also an after-market for other brands
I got this at an estate sale. The owner said it was for a Harley Knucklehead. I could not find anything that looks like it. All I know is it is a lever with a knob. Maybe that is all we will ever know about this.
handle doesn't look like something that would have been in a factory setting, sort of crudely done
the handle was welded and not finished off
also reheated in a few places to make bends
you can see the heating marks from the weld and heating marks from a torch
IMO
