i have a sporttrax250 and want to get a 400 which is better for mx bc i do a lot of it?, which as better top speed and acceleration?

 

I would say z400.....They both do a well job,but i think the z does a little better(IMO)

 

I dont know between which would be faster for 06' cause honda made the trx400 quite abit better. As for suspension on the 400 level machines I believe its hard to beat the stock suspension and handling of the honda 400...its amazing.

 

Haven't u heard bout the new z400's suspension???[img]i/expressions/face-icon-small-confused.gif[/img]

 

The rear shock on the z is decent but even with the updated fronts, overall takin into account just ergonomics, suspension, handling, etc its hard to beat the honda 400. I think the z is really close.

 

so r u saying the trx400 would be a better buy?

 

the 400ex is a great quad but i'd take the z400 anyday over the honda

 

Both are great machines. I personally own both a 400ex and a Z400. Me and my wife race XC and as nice a bike as the 400 is after boring the motor out for racing heat dissapation is such a problem I don't know how much of a problem with heat you MX guys have but you die by it in XC with all the mud. I added a oversized oil tank to the ex (which is bored to 428 by the way) and we still couldn't keep the motor as cool as I would like. That is why we switched to the Z400 for this year. Liquid cooled is so much better than air cooled. That is why you don't see YFZ450's that are air cooled. If you plan on rec riding then I would go with a 400ex. Very reliable and great handling. Plus it has reverse now which is always nice. If you plan to race I would go with the Z400. Liquid cooled and its got a ton and a half aftermarked parts all lined up. Pick what you want and hit the track.

 

Didn't you post this same thing in the honda forum.

 

ditto that
