This really depends upon the manufacturer and model of your scooter, but a 150 cc scooter will generally top out at about 60-65 mph. The cheaper Chinese models will only do about 50-55 mph, while good Hondas will go up to 65 mph. I had an 86 Honda Elite 150 scooter, and it would do about 63 mph with me on it.
Small 50cc scooters (Mopeds) are good for about 30 mph, maybe 35 mph in some states without speed restrictions. They will just about keep up with urban traffic, but you have to ride them WOT (Wide Open Throttle) do do that.
