Well, if you didn't have a frame at all, there wouldn't be anything to tie the parts together with. And a pile of loose parts on the floor wouldn't be going anywhere, at any speed.
So the question only makes sense if you compare different frames to each other. A lighter frame will make the bike accelerate faster but won't really do anything for top speed. A stiffer frame can make the bike handle better, which might mean that you dare to ride it faster. A stiffer frame can also do a better job of getting the power into the ground, again improving acceleration.
At the extreme end some frames can be more aerodymanic than other, also improving top speed a tiny bit.
how to make a pocket bike faster.
yes the 125 with the 80 frame is goin to go a little bit faster because it is light it probaly feels like it has more torque too because it will pop up wheelies faster but probaly the 125 with the cr 80 frame.
it will make you faster, but only if it is streamlined. other than this it protects your head if you fall off your bike.
Replace the motor.
Twist the grip.
Lose weight.
put a bigger engine in it!

A bore kit does not make a bike faster. It makes the engine more powerful if you want to go faster you must work on gear ratios and or sprocket sizes.
no
A +5 kit from mykwilwin it makes is 5mph faster
You can put more gears in the bicycle.
