I had the same problem two weeks ago, brought to Ubi TP Station ownership record of my ex bike, letter from the driving school stating that I was tested with a 650cc bike and they didn't accept it. I was given 2B only.
They want a record of my practice exam from my home country's authority stating the type of motorcycle (and its cc) I was tested with. I am Italian and after checking with endless and expensive phone calls with the authorities, basically i have been told that this records or documents do not exist in Italy. I am now in touch with a lawyer to try to sort this thing out.
Is anybody here who is Italian and got the Class 2? I can pay well just to know how you did it
