How many links does Honda primary chain 13610-393-004 have?

One 50-link internal primary chain replacing Honda OEM 13610-393-004 is included for the listed CB750 applications.

Does the 50-link primary chain fit every 1969-82 Honda CB750?

No. It fits the 1976-78 CB750A Hondamatic and the listed 1979-83 DOHC CB750 models. It is not the primary chain for the 1969-78 SOHC CB750K or CB750F; the CB750A is the specific pre-1979 exception shown in the fitment.
