Front brake disc surfacing?

[montmil]

Is it possible and/or practical to surface (turn) the front brake rotor on the R65?

The minimum thickness of the rotors is .180 in.

Best guess is that the bottoms of the grooves would put it in the minimum thickness area after turning them down.

The rotors are stainless steel, I'm not sure how difficult it would be to machine them.

OEM replacement rotors are around $240 each, and aftermarket rotors like EBC steel are a bit less costly if you look around for them.

Groovy!  That's my front disc, not my lifestyle. Break out the calipers looking for over 0.180 inch. There's a machine shop in town where the owner keeps his motor coach and big, enclosed  scooter trailer parked. Think they're MXers but he might stoop to help a beemer owner.  Measure first...  Thanks.

This is what my rotor looked like.  I didn't even consider having it resurfaced.  
Common knowledge/theory is that these OEM rotors are not "turnable", like cars.
I replaced it with a EBC rotor.

Hum... Thought you'd found a photo of my bike's front disc.

Stainless Steel is a PITA to machine and that's what those rotors are made of. I'm doubtful that your local brake shop would be equipped to cut them. If you do find a machinist that will turn them I'd love to know!!
