True enough, I have a solo seat on my 750 Aero and I only weight about 162. Just the other day, I decided to wring her out in 4th gear. She was pulling 85 and had more throttle to go. I believe my 750 will hit 100, just need to find the road to do it, ie. no traffic. My 750 seems to have just a little bit juice than my 1200XL 2000 Sportster had. Plenty enough power and plenty of enough speed for me.
