Buying a used motorbike

Hello all!
I'm planning to buy a used motorbike from a local in PP.
The motorbike has already licence plate and tax paid for the current year.

Do I need any particular paperwork to transfer the registration to our name? Is the licence and ID copy enough?
How does that work?
Someone has experience with this process?
Thank you.

No personal experience, but from what I heard, you don't need to transfer the registration. The original registration card is your proof of ownership, but you should only carry a copy with you.
