stock 110cc pocket bikes can go anywhere from 55mph to 70+mph depending on the model. with performance parts, they can go much faster.
One way to make a 49cc pocketbike faster is to get a performance airfilter, or a new muffler, or a new carbureator. You can find all kinds of parts for pocketbikes and gas scooters at www.partsforscooters.com they have performance parts of all kinds of scooters and poketbikes and dirtbikes and they also have stock original parts that came with the vehicle you purchased
take parts off that u dont need to make the pocket bike go faster LOOSE SOME WEIGHT OR BUY PERFORMANCE PARTS remove the muffler, remove plastic pieces that are not needed, bore out the cylinders and get bigger pistons, swap sprockets or get a smaller rear sprocket. (this will make it slower off the line but significantly increase top speed. just like a mountain bike in low gear)
X1 is taller and little bigger but x7 is faster.

What you can do is on most of the pocket bike carburetors there is a little screw that you can a dust that will increase the speed
X2 is cause it has CVT Transmission which means runs on belt and it goes around 40-45mph.
2 srokes have powerband (response) and they rev higher = more power
sit on it and turn the srew . when it feels like its about to go faster or pull hardest that's it
It really depends on what kind of bike you are getting, but normally, a pocket bike is bigger.
