I thought this was an interesting topic and since it seems inaccessible in it's current location I thought I would try and resurrect it here.
I think just about any scooter over 300cc's can do go over 80MPH although I certainly wouldn't want to keep riding for any time at that speed on a 300cc scoot, it would have to be at least a 400 to do that. The best scoot to do this on of course would be the Aprilia SRV850 since it generates 76HP i'm sure it could cruise comfortably all day at 80MPH.
