Topic: CB350F and CB400F frames interchangable??

[thirdman]

I know that the headset/forks/brakes/wheels on a CB400F and CB300F are interchangeable, and that it appears that the engines have the same mounting points, but now I have heard that the frames are actually identical.    I heard from the same source that the swingarm is different, though...

Could this really be true?  Does anyone know for sure?

your guess is as good as mine... ok well, maybe not.  i have both of these bikes but did not experience the resto on the 350   BUT, when i dig into the 400 (see signature links) i will be able to give much info (i hope)
