I have a 2002 ACE 750 and going to Dallas other weekend, I hit strong headwinds (front blowing in) and with the throttle wide open, I was topping out at 80 mph. I could hit 90 going downhill. I do have a large windshield so the air blasting that was a slowdown, too, but what's the average top end speed one can expect out of a 750. Surely it can do more than that???????
