i was looking for more of a mph answer i was thinkin 80-85 would that be around right

With stock gearing and tires it'll most likely hit the rev. limiter before 80mph.

No, a stock YFZ tops out at 75 + or - depending on rider weight, etc... with stock gearing and tires, where the f do you get your info.? And as far as it being "impossible" for a yfz to reach above 75...mine does upper 90's with 22in. tires and 15t front sprocket and I know of bikes doing 100+. Dumb ***.

what better does the 15t do to your quad
