Both stock,depending on race strip,let's say quarter mile on: the 400 ex.anything less then a quarter mile the yz
the blaster
i raced my friend on my 07 400ex and i smoked his 06 300ex and he had his HMF slipe on pipe to.
the yz85 is faster because it has so much top end and no power valves and the kx does. in a race a yz would win but it is 10% bike / 90% rider
The yz would always win because its a 2 stroke race bike. Even the yz85 would beat the crf150r or the crf150f.
The 250R is going to win
Yes it would all the models are almost the exact same.
Yz 85 all the way 2 stroke 85 =170 4 stroke
how to time a 2002 400ex
Obviously yz125 is more faster than yz85.
400ex does 60 tops.
Yes someone who is 56 will fit on it no dout?
the stock 400ex has 29.3 at 6900 rpm
