Cupping or normal wear

This is the rear BT016 on my 250 and was wondering if this was normal wear or cupping from under/over inflated tired? I'm running 31 psi.

31psi sounds low. I run 4-5psi higher than specified for most occasions (36-38 psi).

Under inflation does cause cupping. That seems way low for the street. For the street I always inflate to manufacturer's specs. Check the swingarm placard or your owner's manual.

Low pressure cupping.
For street use I'd recommend 36-38 psi. In the front.

IMO owners manual tire pressure recommendations are for stock tires only. That might get u in the ball park but it's "recommended".

As Patrick stated try 36-38psi...

and Cuong, remember when you add more air in the tires,(especially on the the front tires) if your used to riding it on 31psi and you pump it up to 36-38psi, know that the bike will LEAN into the turn a LOT faster.
Don't be caught off guard by turning into corners like you normally do with the 31psi or air in your tires. Feel the way the bike turns after you pump the tires up to 36-38psi, so you don't dump it going into a turn. IMHO...
