[QUOTE="jmics19067, post: 706231, member: 27963"] ;) 1 thing to consider is that steel bars has the cross bar welded straight across the middle section and aluminum bars have a pivot point on the ends of the crossbar slightly higher than where they are fixed to the handlebars. This would allow some flex. Of course the big handlebars with no cross bar have more flex yet. All materials will fail with repeated stress cycles it is only a question of when,with overloading,crash damage, wear and the useful life of the rest of the bike being exceeded being more common. If never crashed aluminum bars would probably fatigue faster than steel but since the steel bars are easier to bend and more likely to be bent back into shape they will fail faster than the aluminum. I say probably only because aluminum tends to have weaker fatigue properties than steel but it would take a good engineer with the proper numbers of cycle loading ,wide sprectrum cumulative fatigue and the physical properties of the different handlebars to truthfully answer that.
