Nope, the opposite is true. Because handlebars all have the same outside dimesions, a Ti bar will be far stiffer than it's aluminum counterpart-check out ti's elastic modulus compared to that of aluminum. Generally, I think there one major reason why ti bars are not popular. Cost. It is very expensive to produce a ti bar that is comparable to an aluminum bar (bulged center, tapered wall etc.) Dollar for dollar, aluminum will always come out on top. Additionally, even a very advanced ti bar will probably be close in wieght to an aluminum bar. Hard to justify the expense.
