What would be a good dirt bike for me?

I am 14 and used to have a pit bike when i was like 10 so i kind of know how to ride but it was a pit bike so not that well. I am 6ft tall and 170 pounds i think a four stroke would be better for me because i am not that experienced i was thinking of the honda crf 230 but is that good and if i did choose to get a two stroke what would be good for me?
