    The biggest problem with risers is the very long bolts required. When coupled with very strong bars, and a crash, the force transmitted through those strong bars can break a bolt(s) off or worse, trash the upper t-clamp . A good case for cheaper, more bendable handlebars. You can get home with bent bars.... not so great if the bars are no longer attached to the upper T-clamp. You think new bars are expensive, try buying a new upper T-clamp!

    Not all risers work this way.

    Whether you raise the bars using risers or taller bars, if you raise them the same amount, the moment from the end of the bars to the clamp will be increased the same. The only way you're going to break something is if it was too weak to begin with or overtightened. I guess if you have to overtighten bar risers because the clamp is not as effective that could contribute but that's a flaw in the clamp, not an intrinsic result of using a bar riser.

    My point here is that a combination of a very strong bar and risers causes a bigger twist at the point of mounting than the T-clamp was designed for. In most cases the 4 bolts securing the bar are pretty close together. You could even make the case that the increased leverage caused by stronger bars without risers has that same effect. We are talking about twisting leverage in 2 directions when you fall, up and back. A lot of force is transmitted to those 4 small bolts. They bear most of the brunt of that twist as well as what they bolt into.

    It seems like breaking the bolts in a crash would be preferable to breaking anything else, as the bolts are easily replaceable.

    Yup, that's what I did on my DR350. Looks great, functions well and was only $50.
