How can i get my parents to buy me a dirt bike?

masee Asked: How can i get my parents to buy me a dirt bike?

For the past four or more years i have wanted to get a dirt bike but no mater what i can not seem to get through to my parents that i can handle the responsibility of owning one. in the pass i have saved up half the cost of buying one but my mom kept saying that i am not aloud to have one even though she said it would be nice for me to have one. how can i convince them to let me get one.
