Whaich is a faster more agressive quad? I would take the quadracer but do you guys think the z-400 is high performance enough to stay with the quadracer?

 

I can't speak for the Z400 but the Quadracer is plenty fast and has pretty good suspension. The biggest differences will be that the Quadracer weighs less, the front suspension uses less advanced geometry, its a 2 stroke and doesn't have reverse. The Z400 is a more versatle quad since you could do any type of riding on it while the Quadracer is better for duning and wide open areas. If you found a really good deal on a Quadracer I wouldn't pass it up.
