I have used 120/70, 130/70, 130/80, even a 120/80 I had on hand.
Some folks are pretty sure the bike - any bike - is unrideable without the stock size and brand of tires on both ends, and they should definitely use those.
I found they all worked OK after a short period of adaptation. Going from a shagged front to a brand new one is a much greater change! The 130 are a little slower handling, but no reason to be freaking out. Opinion only of course.
