Just a guess, but newer immobilization systems typically have a permanent RFID "code" for each and every key that makes it unique, which means they usually need to program the vehicle to accept that new "code" as having permission to start it. Despite having great aftermarket software that allows you TONS of coding and adaptation options on VWs for the past 15 years or so, programming keys still requires deep digging (that only most tuners can do) in the ECU file for an "SKC" that is needed to tell the ECU to accept new keys.
If it really bothers you, one workaround (or at least on VWs it has been done, the theory would be the same here) is to remove the RFID "pill" from a functioning key, and permanently mount it within range of the sensor antenna. This would obviously make the bike a whole lot easier to steal.. though most thieves would assume the bike had a working immobilizer function and likely pass it up anyway.
