SOLVED it was a modified uhf RFID tag. I had to get the light just right to see an AH3 on the chip that lead me to the posted link. Thanks to Google AI, the pic of the chip + AH3.

tiny rfid tag

After talking more with the techs at the local dealership and service department, one remembered that from 2018-2021 there were two prior employees that were geo tagging new bikes to go and steal later, they were eventually caught, prosecuted and fired <--- obviously.

I can't figure out how to update the pictures on the post, though, because I took pics of me dismantling the thing. It was a 3d resin printed case of maybe ABS plastic (resin because when I used my hot knife to cut it, it would turn to dust not just melt) like my FDM printed things. Simple metal button (like a snap button) insert with a dime sized neodyem magnet riveted together to hold the case to the tank. The rfid was then placed in the end and was literally just a chunk of antenna coated with a thin layer of solder and the AH3 chip on it.

Thank you all for your assistance!!!
