400ex's are capable but as always its not made from the factory that way so its gunna get beat. The 450r is factory built that fast so it will last alot longer than a modifyed 400. But it is possible, my brothers 400 eats stock 450s.

In case anybody wondered, the stock 450R is 42.6 HP and the stock 400EX is 34.2 HP. This info was taken from the CARB (California Air Resource Board)certifications.

Yeah pretty much. Any built fourwheeler isnt gunna last as long as a stock one. I dont care how good of a motor builder anyone is. The factory build has been tested and abused and tested some more. Honda does there homework when building these things.
