If the riders were at equal levels, would a 2000 Honda 400EX with an aftermarket pipe and K&N Filter keep up or beat out a 2006 Suzuki 400Z?

 

Welcome to the forum Emmitt, I would say no.

 

I own both. The Z is quite a bit faster than the EX. My EX has a full aftermarket exhaust, vented airbox lid, etc. I was riding with a stock Z once, down a long desert wash. The Z just slowly walked away from me, no matter what I did.

 

Dirt Wheels had a shootout with those two. and the Z beat the ex all the way around. I myself like the Z best.

 

i agree with everyone else, the Z should win easily. the 400 might be fast for what it is, but its very old technology compaired to the Z400

 

Thanks for the info...I may do the mods anyway for me...just wanted to know everyone's opinions.

 

I have a custom EX, no motor work aside from LTE exhaust, filter and CDI. Installed a 14t front sprocket and hillshooting against a piped Z-400 I was able to win by 1/2 quad length at most. The difference was that the sprocket in the sand helped me hold 3rd gear longer, and my suspension system gave me the needed edge through the whoops, so I could carry a higher speed at the bottom of the hill.

That said, if I was to buy today, I'd get the Z. It is a real nice quad.

If you have an EX, do the basics, have fun and remember that while you can go faster on other quads, your EX motor will probably last longer between rebuilds than the new crop of 4 strokes.
