What is the real world top speed of the new GTS and Primavera models.

I have read and heard so many conflicting numbers.

Not looking for results from modded bikes. Strictly 2023 stock models.

I am looking at purchasing either a Primavera or a GTS and I am wondering what the real top ends are?

I have heard everything from 57-58mph to 63-65 mph for the Primavera.

And I have heard everything from 75-78 to 83-85 for the GTS models. Please help me out here!

My suspicions are 60 mph would be a good result on a Primavera, and 80 would be quite good result on a GTS
