Not all of these bicycle motors have bearings, (ball or roller) in the wristpin location....some (most) have a bushing there.

Also, piston skirt clearance.

I was being a little sarcastic about the break in thing.....most of the ring seating is done within the first several minutes of running, (30-60).
