13 year old's bike

i am a 13 year old with a low budget and no experience on a dirtbike, and i was thinking of getting a 1984 yz 80. Is this bike to powerful for me? If so what do you recomend?

I think 80's are great bikes to learn on, once you learn to balance and distribute your weight properly you can have alot of fun with the smaller dirtbikes.

yz 80s have plenty of power even for guys around 150 to just go out and play on
