A four stroke will not develop as much torque as a same displacement two stroke.


You are correct that it burns the charge more effeciently. A four stroke will achieve a higher cylinder pressure, due to the fact that it's cylinder is more completely filled with combustible gas during induction. However it's actual mean torque is halved compared to the engine's brake mean effective pressure because of the alternate firing.

That is my last word on the subject.
