New wheels for ktm 450?

Honestly aside from some ergo stuff (bars, levers, grips, etc.) in my opinion just leave it stock for now. Ride it a lot, and get a baseline for what you think you may want to change then pick up from there. I currently ride a 19' 450 sxf and have been on KTM 450's since my 15 FE. The bikes are incredible in stock form and really dont need much.

I run a Faster USA wheelset and have had great results with them. I definetly would not run that Chinese wheelset over stock.
