throttle of the line

[possopo]

a person is talking about top fuel bikes:

"you need enough balls to be able to know the throttle off the line."

i guess he 's saying that hitting the accelerator requires balls.

am i right?

It's an American English and (I'm guessing) a British English expression that is considered rather Earthy. (That is, it is not used in polite company.) A dictionary would probably call it a vulgarity. The "balls" being referred to are testicles. What is means is that it takes a lot of guts, or nerve, to do the thing under discussion.

i know what balls are, my question was more about the second part of the sentence "to know the throttle of the line":)

Oh. Sorry. I was hoping it was a question I could answer.
