Advice on '07 690SM Rotor Upgrade

[SteveNC]

I have a 2007 KTM 690SM (I Spy version) and the front rotor is slightly warped. So I was thinking that if I'm going to spend the money to fix it that I may as well check my options of a better rotor and pads. I'm not having any luck though finding a company the has a rotor upgrade for this bike. I know that it was probably cost prohibitive for a brake company to market them due to the low sales volume that bike experienced. Any suggestions? Thanks in advance.
