I once took my 500 up to an indicated 88. I'm told they will run out of steam around 94-95. I believe that as it certainly wasn't done. It cruises very willingly in the 70's, but I'm not young anymore and prefer the middle 60's or our 2 lane roads in the 60 and below range. To really enjoy a scooter, IMO, find a lonely, winding, 2 lane blacktop and run about 45. Pure heaven.
