I've been told that they have been clocked at close to the 20 mph mark, with a stock setup. You need to keep in mind though that that is with fresh batteries, and most likely with the highest speed pinion added to it. I do not know if that is with the stock motor or the X-Speed unit, but from what I have seen between the stock and X-speed motors, I highly doubt that there is more than a 1 mph top end difference.. Hope this helps answer your question.
