Particularly, this one with the 30mm forks.

OOPS! Apologies to pokey.  That came across as rather "Dickish" :-[
I was posting at the same time and had saved the link to the 30mm page,
but it just takes you back to the main list.

Get the hone out.

Honda has 31mm leading axle forks from CR125 (rarer)  to 76-77 XL125 (plentiful).
