z400 and kfx400 have the same motor but they have frame problems (i think)

400ex lasts along time, but i havent had mine for too long, i havent had a major problem yet

DVX is also the same.

I have had my 400EX for almost 7 years now, and it still runs super-strong, and hasn't had any problems up until my build ( Occuring now). Only good things to say.:D

I've had my 400ex for 6 years now- put it through some serious punishment, other than routine service ie; changeing bearings, oil , valve adjustment and 1 overbore size, which is common practice- I've had no problems from it.
