Many Thanks Andy...
The main problem is that Authorities here in Spain do not accept data from a website source. Only from "official" ones, like Honda itself and vehicle registration offices ....
By searching and searching I found a website from Japan Inspection Authorities, Which are able to issue a year of manufacture certificate IF the bike was already driven and registered (which is my case) in Japan.
I think it could be useful if other subscribers are looking for this. It is a PAID service, but anyway worth it.
This is the website address: https://japaninspection.org/vehicle-manufacturing-year-verification/
Hope will be useful.
Many thanks and have a good day !!!
