Default Re: 2 vs. 4 Stroke...

4 strokes generally cost more, last longer, are quieter, use less gas, pollute less, don't require oil mixed in the gas, make slightly less power per displacement, Have a broader torque curve, and foul plugs less.

I'd generally say that a 4 stroke is better in most ways. The exception is in maximum power, where a 2 stroke usually is a little bit better, weight, and cost.
