I've been searching for a long time for an aftermarket stand. No one will take the time to produce one since this bike is considered uncommon. Even though they've been around since '08 and KTM sells every one they import, they are too few and far between. You'll have to fabricate one yourself or mod the stock part. I shortened mine 1" and added a post to help me kick-up the stand, I have a short inseam.
If I'm not mistaken, CJ Designs will modify your stock kick stand and make it an adjustable-length kick stand for $125. So far thats all I've been able to find.
