I saw your friends grande at stinko and and flock yeah, and wasnt that impressed by its performance, which is what lead me to my post. I figured maybe that motor hits 65 at best. You would be surpised how little gearing makes a difference over 60. Its all wind resistance. Its like people hitting 60 with stock gearing on their gila who think they are going to easily do 75 once they gear it out. Doesnt happen. They get 5 mph on the top end. 80 wont happen. Skeptical that you could break much more than 70 with gearing with any kind of gearing that would be practical to actually ride.
