    bent wheels

    would you trust a wheel that was severly bent then straightend.
    its a front wheel on a tlr that likes to wheelie alot.

    the shop that did the job got it true but they used a press to straighten it
    what concerns me is it induces alot of stress into the wheel. i'm worried that
    it might crack or a chunk might brake off after a landing from a wheelie.

    any input or experience on this subject would be appreciated.

    Aluminum doesn't like being bent multiple times. If you will be putting the wheel under more than average stress, it's one of those situations where it's probably not worth it to find out if you are right or not. I would replace it. I'm reasonably certain that there are wheels that will cross over (GSXR to TLR), so that should make it pretty easy right?

    good luck

    It Is not worth your safety to ride with a wheel that was severly bent...Especialy if you didnt even get it NDT'd....when tempered aluminum is bent then rebent it causes a stress riser in the area bent...it may look ok and might even pass an inspection but metalurgicaly the grain has been altered...what forces that will cause a failure is not coming down from a wheelie it is the centrifical force generated at high speeds....the exact time when you do not want a front wheel to fly apart....

    Can it be heat treated/stress relieved for a decent cost?

    Probably not for less than an ebay wheel, but that is a moot point because once aluminum is bent, then bent back the way it was previously a weakness will always be there. A sheet of normal paper is a good example. If you fold it in half, then bend it back the other way, there will be a permanent, unfixable weakness along the crease line. The only heat treatment that would fix the wheel would be to melt it down and re-cast it.

    Yup. Cast aluminum shouldn't be bent, ever. Replace that wheel.

    For those wondering, NDT is an acronym for "non destructive testing"
