The reason for that is that a 6o 2-stroke is comparable to a 90 4-stroke. If you look at an airplanes specs, it will usually say something like:
Engine size:
60 - 90 (2-stroke)
90 - 120 (4-stroke)
No doubt about it, 2-strokes are smaller with more power-to-weight ratio than 4's.
4's are just so sweet. But for a beginner, I'd stick with a 2.
