Direct bolt in NO. You would have to fab the mounts. Also not sure where you would stick the radiator.

dude check out the hybrid section they will telll you all you need to know and if you fab the mounts i think you could get it to work ive seen may of 400ex's with crf 450 motors it if you do do it post some pics of the build...good luck:devil:
