It sounds like, under the circumstances, the NC700X is performing as expected. About all you could do for improvement is remove the Madstad, put a stock screen on it, and ride in a tuck. You could possibly fine tune the gearing a bit to maximize top speed potential. If you really need to go faster than 95 mph, perhaps trade for a different motorcycle.
No one on the forum in the past 6 years has expressed much concern over top speed, so we don't have experience to draw upon. I've never had need to go over 75 mph, so I have no idea what my NC's top speed might be.
