Is the 400EX a good MX quad?...what chassis mods...motor mods...help appreciated!

 

It is an GREAT flier, just add a better suspension frt & Bck and you have it done, you can play with in the air, feels very light.

For race you have to do first:
1-Suspencion and wider stand.
2-You have to be in a very good physical shape.
3- Nerfbars and handlebars
4- Motor mods
5- Low profile Tires

Unless you are a top notch pro a 400EX will be one of the best choices for MX'ing. The Dales are better, but cost more, and the Z-400 is good too, but when it comes right down to it in the amature classes it's mainly the rider that's going to decide whether or not you'll do good. The EX is down on power, if you demad a lot of power (pro) but the chassis makes up for it.


440 big bore kit
Slip on muffler
Some good sprokes, and chain (the stock one likely will stretch quickly)

That's about it, unless you are a very competitive racer.

 

I was thinking about a 310R also....

 

the 310 would be a good MX'er. The honda's (EX, R) handle the track very well, and chances are if you make it a 310R you'll have more into the chassis too.

BTW nice dune machines on your web site!

 

I dont know what to go with as far as motor modifications...?? on the 400EX

 

By the look's of the quads in your stable, i think you'd need more power from the EX, so a big bore kit, muffler, and mabey a wider stance would do. The power that a dune quad has, isn't needed in a MX quad, handling is more of an asset.

 

Those arent my bikes im just in the riding group NXT-LVL RACING...but Take a look at this site
CT 440 kit Its the first kit for $1225 ive decided on this kit and Lonestar +1 +2 A-arms,Braided F/ lines, works Triple Rates w/ Res, Axcalibur Axle keep in mind I'll be 16 in April...this is what I have chosen for Chassis and Motor mods....there will be lots of other mods

 

hey i ride a mx track all the time on mine.
my buddis have z400 and ex as well . the mods i have done work well , good bottem end power..
but the suspension is in need of an upgrade on both models,,especially the front shocks...
they work very well jumping ,,, we can just bout keep up with the bikes...
good luck
