I believe Honda itself has made that choice for you. They make what sells and technology marches foreward. Honda could have chosen to update the XR more than they have but chose not to as it is basically the same since 97. They are doing the same thing now with their CR250, not putting any changes into it in several years. It is now outdated while the others have moved foreward. For better or worse Honda has replaced your bike with the 450X, it would be nice to have them both available. Parts for your bike will be available for years, keep it if it pleases you.
