I am thinking of upgrading to an atv that could be a race quad. I pretty much have decided on the Honda 400ex or Suzuki z400. Which one would be best for the track. Thanks

 

z400 no doubt. Especially if you go for an '05. Much quicker, much better suspension. Price-wise they are the same so it makes sense to go for the z400.

 

their both good quads .just the z is a little more updated than the ex.in my opinion if your looking at a race quad you might want to look at the yfz or the 450r.its going to cost a lot more $$$ to make the ex or z race ready.

 

i agree^^^

 

The Z by far! A 450 would be even better.
