Brake rotor resurfacing

[Galactica]

Does anyone know of, or can recommend someone who can resurface the rotor from my 1975 CB750?

Thanks,

  My experience with motorcycle rotors generally it is understood that there’s not much material on them to get the opportunity to “clean it up” and still be within minimum thickness.

These things are pretty beefy.  I’m sure there’s lots of meat on it.

I have sandblasted rotors before. It helps on the grip side.

Damn the torpedos.  I did a bit of reading about resurfacing these rotors.  It seems you only get about 20 thou to remove from each side.  And because of the hard stainless material, it’s recommended to grind rather than turn.  So I bit the bullet and ordered a new rotor.  Could have saved some $ by ordering through the US and shipping to a US address.  But considering current border issues, the ship $ saved wouldn’t be worth the hassle.  And I’ll have it in hand from the Ontario supplier early next week.

Rotors on modern bikes are much thinner than older ones, 4.5mm vs 7mm.

Our buddy Murry at Modern Motorcycles used to resurface rotors.  Not sure if that's still the case or not.
