Trying to ID this old Honda wrench. I think its a 45mm shock adjustment wrench for maybe a 450 or 750 but I've never seen one quite like it. Any help is appreciated!

I think you are right in use.  Pin spanners are quite common. I had a bunch. If used carefully they can be used in place of the similar ones  with a wider blade for the nuts on wheels.

Thanks for the reply - I think it was OEM in a tool kit for a late 60's or early 70's Honda CB - I am trying to narrow down which bike / year it goes with.

1968 CL175

Thanks, Kirk

Thanks - Good to hear from you!
