CRF450 dirtbike how fast r they???

[Paulie B]

For a couple weeks I've been hearing my neighbor riding an insanely loud dirtbike around his woods. I got to see it today riding down the street. Apparently no one told him that everything I can see and hear from my house is 400 Blaster territory!!!
How quick are these things? From the looks of his street take offs it's bark is worse then it's bite.
Do I have a chance?
Yeah yeah I hear you "Jes race and find out"
No one wants to be embarrassed foot steps from their house
