Topic: which rotor is which...

[alacrity]

Sorry if I missed it, but a search didn't turn up a nice single list of all the front rotors on our various CB bikes.  I picked up a rotor at a swap meet a while back and it's a "smidge" bigger than a cb550 rotor.
I am gonna put it up for sale and wanted to check a reference or two to be sure which bike(s) it fits before hand.

ANyone got a link?

thanks

What's a "smidge"?

[754]

750 rotor is about 1.6 smidges bigger than 500 rotors..

I believe the 550 rotors have a 270mm or 275mm diameter (can't remember which) while the 750 rotors have a 295mm diameter.

Hmm, then 1 smidge equals 12.5 mm, or .492"??! I always thought a smidge was much less, but thankfully I haven't had to deal with the Smidge system since selling the '53 BSA.

A smidge falls between a tad and a bit, as described in the rare 7side bolt head wankworth system
