Which is faster in these areas:

Drag?
Sand?
Woods?
Track?

 

The Z in all of them.

 

The 400ex is a great machine with uncompromised reliability and handling. That said, the z is no slouch.

drag, - z stock, z when modded
sand, - same as above
woods - close call, speed of z in the straights might push it ahead.
track - close call, speed of z might push it ahead.

 

The Z is a little faster for the most part but it usually comes down to the better rider between these two...............[img]i/expressions/face-icon-small-cool.gif[/img]

 

The EX still has it beat on reliability by a long shot, and from what I hear it has more low end torque, but everywhere else the Z wins. The EX is said to be one of the most stable quads out there and the Z is almost an exact copy of the frame, so they handle very similarly. Z all the way though.
