I have only half the miles on my 2013,but my rear sprocket looks like new.My guess from looking at the picture is that you have been running belt too tight and off center to sprocket.One good thing is that it is easier to replace sprocket than a belt.

Yup have a sprocket hanging on my wall that looks very similar. Had a new tire installed at the dealership right before I came home from overseas, as I had a big ride planned. They installed the belt way to tight, and the rear wheel was 1/16 out of alignment, which is technically ok, but I normally do my own and do it perfectly. The tight belt causes that wear, and the off alignment can cause the belt to wander back and forth, which it looks like yours did. Never mind the additional tire wear...

Belt deflection as measured by the window in the belt guard has always been right in the center. Is that too tight?

Any chance you ride on salty roads in the colder months? Mine looks a little like that and that's what I chalk it up to.
*edit* never mind I was looking at the pic on my phone and when I looked closer I see it's mainly on the one side. Mine looks bad evenly across.

There is a very useful deflection tool for checking belt tension, the one H-D tool worth having! It's the best way to check tension IMHO, which it does by pressing upwards on the belt by a measured amount. You check how much it moves by looking through that window. Well worth checking tension and setting it right, if necessary.

But I'm still puzzled as to what causes what I'm seeing on the rotor. Would a too-tight belt cause it? The tech wasnt sure, he speculated "hard riding". I doubt its that.

Mine has looked like that for several years now with apparently no adverse affects. It looks like chrome peeling off mine. They say to change belt and both sprockets as a set. I will go with the bigger rear sprocket when I do mine.
