Is this a rare speedo drive?

been doing some research online, I don't seem to see any xs650s with this kind of speedo, is is possibly from another bike all together?

of course, I find it right after I post. I didnt think to search honda. it appears to perfectly match a honda cb500 front wheel, the disk, axle, speedo all look exactly like an early 70s.
Oh well... will sell them off I guess. I have front and rear complete.

It doesn't look like any I've seen on an XS650. But it may be. I have seen many of the early years.
It does look like an XS650 wheel.
I am looking up the early parts on boats.net. It takes awhile, I have dial up.
