Questions regarding storage in Costa/Rica and Panama from a "newbie"

[kuebeldoktor]

Hello experts,

I will drive with a friend on two BMW 650 the Panamericana. We drive in different sections because we only have about 2-3 weeks per tour. Now I'm planning the tour from Mexico City to Costa Rica or Panama and need fresh information regarding the local storage possibilities.
I have already read in the forum but still have some questions:

Costa Rica: We are allowed to park the motorcycles in Costa Rica for 12 months, right (and..is that TRUE ?.... if I put on a day the bikes are confiscated, right?) Cost about $ 3-5 a day?

Panama: assuming cheaper than in Costa Rica, right? (storage possible in David and also Panama City ..panama city would fit better to us?)
And now the main question: may I leave in Panama my motorcycle also 12 months or is only on a shorter period possible ? do you have adresses in Panama City for us ? (but this is only an option to us if 12 month are legal)

Thanks
Frank from Germany
