With the 400EX, Z400 and DVX 400, there comes a point when it would be cheaper and easier just to upgrade to a 450cc machine instead of sinking more money into a 400's dated engine and suspension. For example, if you have grandiose ideas of saving a few thousand by buying a used 400EX, then putting the money you saved into modifications and expecting to whip up on your buddy's TRX450R, think again. Remember the engine builder's motto: "There is no replacement for displacement."
If you are sport-performance-oriented, I'd really recommend shying away from the Raptor 350. Although it's a great little quad the way it is for a cruiser, it does not respond well to mods and is still going to be heavy no matter what you do, so one of the other models would suit you better if you're an aggressive trail rider.
The Honda 300EX is still after all these years just a gem of a quad. It could be the best choice for some riders-again, as long as you are not too performance-oriented. It does everything well, has good balance and is relatively agile.
The Kymco is out of my realm; it's not a model I have done any R&D on. I don't think there's a lot of aftermarket support for many of these import models yet.-Allen Knowles, Owner, CT Racing, www.ctracing.com
