People replace the bars for a variety of reasons: change of riding position, conversion to fatbars, more rigidity/control, more leverage, etc. I think when the day is done, most would admit they just wanted to personalize their bikes some and make them a little more stylish.
I wanted flatter and higher bars, both for street and occasional dirt roads. I've always liked the look of Pro-Taper type bars and they give a smidge more rigidity and a slightly better sense of control. For me, it moved the bike, both in looks and function, closer to the KTM and away from the SV. The stock bars, while completely functional, are cheezy.
But if you're happy with the stock bars, there is no compeling reason to change.
One caution: When the day was done, I had over $500 invested in bar, clamps, throttle lock, hand guards, heated grips, etc. I love it, but if you do the full-meal deal, it all adds up.
