It's a 2019 PCX150.
The radiator cap appears to be plastic or has a plastic guard...any information concerning removal would be greatly appreciated. Tried rotating it by hand with no joy...
Thanks,
Jeff

Seems to be fairly straightforward once you have removed the plastic guard.

As Oldie says it pretty straight forward after you get hands on it.
You need to push down on the radiator cap and turn at the same time.
The cap has a recessed area that prevents it from coming off without intentionally pressing down.

FWIW, the radiator cap on the 2019 PCX is retained by a 10mm hex bolt in the center of the cap. The bolt is captive; use a 10mm socket to remove and install
