You may be confusing flight limit and ultimate load. I happen to have a C150M manual on my desk at the moment. For the normal category the flight (not ultimate) load factors are +4.4, -1.76 while for the Aerobat they are +6, -3. For the P2002JF they are +3.8, -1.9 (all with no flap).
I would not be surprised at the Golf ultimate loading, since presumably Tecnam do satisfy EASA during the certification process of the 2002JF, a similar aircraft. I think there's also the obligatory feel-good wing loading picture somewhere.
