amazing machine. sprocketed my to about 85 mph and it still holds its power. looks great when you get into graphics and pipes.

takes a few after market goodies to make ita"good"ride----I mean competive

i'm 14 with lots of muscle i beat peaple 20 and up with their race quads nothing is better! flys threw mud, and can be handled by anyone. looks awsome can withstand lots of rollling..

Great atv, good power, built well and looks great. Good over all atv. But the 2003 - 2004 had weak frames but they fixed it now.

i love my z 400 ilove it so much im move from bathurst NB canada to swan hills AB a i was only up here for like 3 week so i seen it up cost me 1000 $ but the z 400 have no price on me i love this bike . any one out there thinking of geting a new bike i say go with the z 400 trus me i drove mine bike but the little 400 will kick a$$

118 is pretty fast for a 4-wheeler that tops out at 68mph. I love mine i raced my buddies 04 400 ex and stomped him, I dont even want to trade it in for the 06 450 i am a carberated man. Its funny when dumb ass people try to tell me that their kfx 400 is any diffrent then my z (read your fu**in frame) It is the same damn thing

I bring a Polaris 400, Yamaha Raptor and a Z400 to the dunes. Always ride the Z400 as it's the best handling on the dunes for an agressive rider, hands down. The kids ride the Yamaha and Polaris. Alba exhaust, jetting and intake kit makes this run with any Raptor.

100% pure suzuki junk

I have a Z400 and it is bad ass! Ive raced a 400ex, 300ex, and a kawasaki ninja and beat them all pretty bad. Great all around machine!

I got my Z400 about 3 mounths ago. I have put stage 1 hot cams in it and a moose bub pipe on it. so far i raced a 400ex 2005 and a 2004. Both times they havnt had a chance. I went to the local drag races, an one the whole thing a 4ft tall trophy.

I herd this quad is pretty damn good. I have a raptor 350 and i was just wondering if it was as good as i hear it is

best 400 on the market **** 05 hydrlic shoks ARE TIGHT

the Z400 out beats anything its the best quad out there i topped mine out at 118

this machine has excellent handling, it can out handle the RAPTOR! Rides like a cadillac in the trails!
