I can't help you find some but I can confirm they are/were available as OEM pieces. I'm running a set on my 17 450.
My home track is Reynard's, same as BB60. When Benny got his new bike I got a truckload of shit from him that didn't fit on the 18.5/19 bike. Lots of plastic, seats, seat covers, hand guards, etc. Also included were two brand new sets of the orange KTM louvers. I guarantee they are OEM KTM as Benny had NO aftermarket or Polisport stuff and FWIW they are a perfect 16 Orange color match. They do exist.
