The stability offered with larger tires at speed is really nice. But who knows, you might feel OK with it, I know a lot of people are.
I had my Vino up past 65 riding about 3 miles downhill, including a couple of sharp curves. It handled like it was on rails. The Stella on the other hand starts to feel a little shaky at 55. Large scooters like the Burgmans have relatively small wheels for their size. I think the problem with the Stella is that it does not have enough rake in the front end, but it could be something else.
I would not likely be riding any faster that 65 anyway, even if the speed limit was 75. I would stay in the right lane, put something bright on the back of the scooter to make it visible, and watch my mirrors a lot.
