Spent some time looking into this the other day, found this spec sheet
https://www.ktmshop.se/documents/F9603R5_EN.pdf
Page 32 lists
64111021000 IMMOBILIZER
It will be the stock standard factory immobiliser, like LC8 says for the advanced features like twin circuit etc you'll need the alarm system.
When it comes to security the less information available about it on the internet the better as there's less for criminals to use.
If for insurance purposes, just specify factory fitted immobiliser.
