We all know that the NC700X is not built for speed. Furthermore, nobody on this site condones breaking the law. This is for informational purposes. What is the top speed you have witnessed from a NC700X or NC750X? I will start off with a 0 to 60 mph real quick. around 6 seconds. I have witnessed 90 to 100 mph real slow. please inform the community of any top end speeds on a closed course.
