how much horsepower does a stock '00 400EX have? does any body know how much toque it has at the rear wheels?

 

stock is around 25 I believe but I cant help ya out on the torque.

 

an article i seen said it was 27hp.........

 

[img]i/expressions/face-icon-small-frown.gif[/img] Noooo, it's closer to............18

 

The warrior has 18hp, 400Ex is like they said .. in the range of 25 - 30

 

when it was released in 1999 the mags said 25 , now every year it seems to make more hp stock. hmm...................

 

Keep in mind... tires, elevation, ect, and even each dyno will show different numbers.

 

stock warriors are doing 17.7
stock 400exs are doing 26ish(doesn't state exact hp)
got these off dyno tests

 

a stock 400ex has 24hp cause i just got a white brothers e-series pro-mag pipe for ming and it shows you how much the stock has and then it shows how much the hp increase with the pipe it is 24hp and with the pipe it increase the hp by 6.7hp and the toque i don't know about that.

 

You believe everuthing you read? Exhaust manufacturers always show how much the quad has, before and after, they are almost wrong every time...
