so all the companies or businesses that straighten bent forks and straighten or realign motorcycle frames are actually lucky that none of their repairs have broken apart in use then,
when I'm talking of bending bars I'm not turning a pair of ape hangers into a straight drag bar, they are just being tweaked, in the case of my standard bars the ends have gone forward by about two and a half inches and by the method I use with the vice, the bend is more of a twist in the curved section, given the length of the switch gear section the amount of movement at the actual point of bend is very small, barely any more or even less than how much a bar can bend just by a bike falling over,
for them to break in use I'd suggest that the bending would have to be rather extreme or repeated many times or the metal was badly corroded or damaged in some other way,
to break even something like fencing wire by bending an area of only half an inch can take hundreds of repeated bends to get it to break, but close the bend area down to so small that it kinks the wire then it will break much sooner, I do not do repeated bends and I do not put any kind of kink in the bars,
I know there are many types of metals with differing molecular structures which is why I mentioned the fork and frame businesses,
also don't forget that even standard manufactured frames have cracked in bent and unbent areas due to stresses, I have bent, formed and created many handlebars over the years with none ever breaking, I will be making my own handlebars for my VMAX out of stainless tube because I can not buy any that suit my wrists needs, I have also made many backrests and modified some frames also which none have ever failed to stay together
