I dont know which one is more stabile all I know is that mine handled a tight turn relatively fast and stood straight up I would have never tried it on purpose. even though i watch the motogp races I think those guys are a little off to get that close to the ground at those speeds now they got helmet cams and that view is wicked.

I have no faith in human perfectability. I think that human exertion will have no appreciable effect upon humanity. Man is now only more active - not more happy - nor more wise, than he was 6000 years ago. Edgar Allan Poe
