I agree with you-1 isolated event doesnt prove the tanks are safe, I was responding to the comment of the tank leaking on a rollover, I agree with you that putting the tank up on the cage does effect the center of gravity slightly but it isnt that much weight and most of the time the ody's flip on turns or going backwards down hills, etc.I have flipped mine many times in such a manner and cannot say that the gravity feed tank was the reason for the flips, I would blame it on my poor riding skills-hehehe.I also will agree the tank is mounted on the frame for a reason from Honda, but without the tank there it allows easy access to the side cases, etc and working on the motor, etc is greatly inhanced,just my 2 cents.
