Registering a Scooter

I have a series 3 LI 125 which will be a 175 cc after restoration. I bought it in boxes and am currently just commencing the rebuild.
Sorry if it has been asked before but I have the Nova paperwork and the authentication from LCGB but have heard you need an mot cert in order to register it .
How can I get it to an mot station with no number plate if this is the case ? Do I have to throw it in the back of a van?
