Crank
A crank listed in the oil pump and control pedals figure, likely part of the kickstart mechanism.
57-1680 is a crank listed in the oil pump and control pedals figure, which points to it being a kickstart-related crank rather than anything to do with the engine's mainshaft. Our records show it under the older T1680 number as well, so if your parts book still uses that letter-prefix style, that's the same physical piece.

The catalog appearances we have on file run from 1963 to 1964, but that's just the span our records happen to cover, not a guarantee of exact model fitment. Given the control pedals figure it's associated with, this is likely tied to the kickstart mechanism, but we'd rather you confirm against your own parts book or give us a call before ordering.
We don't have much more detail on this one beyond what's here. If you're not sure this is the right crank for your bike, reach out and we'll sort it out with you.
