Should you get a 90-110cc dirt bike or a 125 bike?

If you are looking into a 4 stroke, I would get a 125cc. A cr 150 would also be a good 4 stroke dirt bike. If you want a two stroke, I would go with a full size 125cc. Any Yz 125, or a 2001 - 2003 kx 125 would be good. Two strokes are jumpy and very fast, so only get one if you are experienced. If ur not very experienced, it might work if you have good throttle control and dont mind a LOT of speed. A 2001 kx 125 is now my first and only bike. I have had it for three weeks, and i love it.
