I would like to know if Duke 250 sprockets can be used in 2017 RC 390

In short, yes. I addressed this in more detail in your other thread at: https://www.rc390-forum.com/forum/track-days-racing/2678-sprockets.html

Also just for future reference for you as I see you're new here... forum etiquette is to try and keep your questions posted to only one location.
