Apparently (confirmed with Kawasaki CS) this version of the kit (matched to the 2022 color scheme) is no longer available and will no longer be produced. I haven't been able to find it on any online parts house, either. So, if anyone bought one and is no longer using it let me know.

The official name and p/n:

KIT,TAIL GRIP,M.D.BLACK

item: 99994-0341-17K

Cheers.
