In all the SAD hype from the so called new Honda ,I've been thinking of hacking and chopping again!! Has anyone tried to put an XR600R motor in an 400EX frame , or checked to see if it's possible??? I think it would be pretty bad if it was done. Finding donor bikes would be the only problem or mabey money. But any way I was just asking ? Don't never know till you ask!!! strong mind weak wallet ha ha ha ha. LATER .....

 

It can be done.

In fact, Laeger's even has a frame available already setup with the XR600 engine mounts.
