Topic: Question about rear sprocket hub compatibility.

[thirdeyeopen23]

Hi, I was in need of a new rear sprocket hub for my 78 cb750k and i was wondering if any of the other years/models of the cb750 have a sprocket hub/assembly  that can be used on my bike. thanks in advance.

The rear is a 41 tooth, and as near as I can tell, it was only also used on the '77 CB750K. If you replace one sprocket (new), you should really replace both. The front is a 15 tooth, and it has the same compatibility. I just replaced both on my '77 CB750K.
