What is your top speed going to be on a x-19 CR dominator?

at minipocketrockets.com you can get a x19 and the top speed for it is 70+ miles...you can go to usapocketbikes.com/x19 to get it cheaper at the same speed but you have to mix the oil if you get it from there but when you go to that website put /x19 or you wont find it. hoped i helped
