Stock 400ex top speed??

[CGriff]

Does anyone know what the top speed of a 400ex is? I'm trying to estimate the top speed difference between running a 16 tooth front sprocket and 15, with 38 in the rear.

about 65 if you tuck in,with the wind:D

Here's a 400EX speed calculator. Just put in the sprocket sizes and tire sizes and click "recalculate".

i want a 0 tooth rear sprocket if it'll really make my top speed infinite!!! :eek: what else can i do to achieve that? a magenta powerband? :confused: :huh

I'm glad I'm not the only one that started plugging in unrealistic numbers to see what would happen :D

the worst part is that i do it every single time that link is posted lol. it never gets old.. i have to say its the first time i've tried a 0 tooth rear sprocket.

give me a 100t front spocket and a 10 tooth rear and ill go 1738 mph!:macho :p

thats pretty cool.
i think its wrong though, becasue i can say that ive done 65 in 4th gear through the big bowls at glamis. (gps)

Take into consideration, your engine also needs enough power to get you to that speed. Even if you gear the quad to run 80mph, if your engine doesnt have the power to propel you to that speed, then your gearing change will be for nought.

Wind speed, direction, your weight, your engines power output, and terrain are all factors that will play into the top speed of your machine. And all I did was scratch the surface of all the variables.:)

I think that calculator isn't too bad. I have a 13 / 41 and it says 55.12mph and my GPS top out at 53.9mph wide open.
