What would the causes be for the rear rotor on a 2011 GSA 1200 with 30K kms to become warped?

I'm just not sure what I should be doing to remedy the situation? It seems to me that having an issue like this with only 30K kms is premature to say the least. The rear wheel is not spinning freely - in addition to replacing the rotor, what other precautions should I consider taking to prevent recurrence?
It's normal, but enough drag to warp the rotor indicates binding.
My bike's previous owner warped the rear rotor in the first 2 years. He was a Harley rider and I suspect that he stopped mostly with the foot brake. I effected a 90% repair with a large blunt object.

As Paul suggested (and yes - it's a floating caliper, not a design I particularly like) - the pins the caliper slides on are likely binding. Yours sounds like an extreme case, but LOTS of hexheads have a rear brake drag that's enough to really heat the rear rotor up, hot enough to burn you - even with no braking.
Cure is - remove the caliper - slide it back and forth on the pins. It loosens up. If it doesn't loosen up, you'll have to get under the little accordion boots to grease the pins with some high temperature grease. Whoever is supposed to be greasing these at the factory must go on break a lot..
