How could you get that brilliant piece of information (2 stroke engines are better than 4 stroke? )
If I am not wrong a 4 stroke 100 cc scooter (that my wife has) has the power of may be 150CC 2 stroke motorcycle (not sure since all the vehicles with me are 4S)
The question is very basic and need not be asked/answered in this forum. Refer your basic text book.

Two stroke engines are still in common use; see lawn mower, leaf blower, off-road recreation vehicles, etc.
But two stroke engines are loud and were quite nasty polluters, so EPA regulations started the trend to the four-stroke engine for on-road use in the USA. Later developments both lightened the engine and improved the responsiveness of the fourstroke so that penetration of the off-road market was practicle. And many areas of off-road use have noise rules.
And once the massive consumer base of the US starts going in a direction, many manufacturers follow.

The EPA was established under the Nixon Administration in the late 1960s or the early 1970s. Essentially all automobile engines in the USA were four-stroke well before that. You will have to look elsewhere for reasons.
One place to look is power curve vs. engine RPMs. Four stroke engines have a much broader curve; two cycles need to run at near constant RPMs.
Sorry my engineering books could not be traced (must have gone to dust)
