Is a 125cc 2 stroke dirt bike the same as a 250cc 4 stroke dirt bike?

im not sure about that but i can say that a 2 stroke 125cc is faster than a 125cc 4 stroke and probably 200cc too. a 125cc 2 stroke would throw you off the back if you cant handle it properly, where as the 4 stroke wouldn't scare the living daylights out of you
