to be honest, it must be visibly twisted for you to say that or maybe you can hear it passing through brake caliper, so i`d say get new one (s) perhaps ( runout measurements dont even come into it )

Don't know what year your bike is, but disks are your life.

They may always work, but on gentle breaking you'll get pulsing through your hand. And, it'll probably need a heavier grip to pull up in an emergency.
Who knows, not sure of the material, but all sorts could happen to the disk in an emergency.
Replace it.

I had warped disks on an old ZZR a while back and it wasn't very nice the pulsing through your hand when feathering the brake.

take your disk lock off next time

Despite a long history of doing exactly the same thing, I rode off with my disc lock, yet again, last year and majorly twisted the disc on my Ural.

This was a Brembo floating disc, ie a steel disc mounted onto an aluminium carrier. the result was that it was the aluminium that bent, and I was able to have it pressed back by a bike shop.

If its a carrier-mounted disc and if it's that carrier that got bent, you may be able to fix it...

OK, you may have thought of this idea too.
I don't know how warped your disk is, or how thick it is, ie how much meat there is to play with. However, it may be possible that a machine shop ( with a large enough lathe) could skim it and get the two surfaces parallel again. Obviously, there is a minimum thickness required, That will depend on how much damage is done. Also, this will shorten the life of the disk. In the long term it may not be worth it. In the short term, it would get you on the road for less.

Also, you mentioned in another thread that you (may) have a front wheel.

Titch.

A wheel that bolts straight on would be perfect. How much are you selling it for?
Is there any way of finding out if Warthog is interested in the near future? I’m getting a bit jumpy now with days left before the MoT runs out.
