    Well that figures...

    So I usually put the bike up on the center stand when parked and yesterday noticed that it was extremely difficult to lift the rear up.

    Then I discovered this.

    What do you all think? Fixable? Would a weld hold up?
    I guess I could always source a used replacement but I rather not if this can be repaired.

    Kinda looks like it was welded before, the welds on the cracked side don't appear the same as the other side... that said, I'd imagine a good weld would work fine. Can't say I've ever seen that happen though

    That absolutely could be repaired by welding it. An easy fix once all the oil and paint is removed

    yes it can be welded, and i would suggest also adding a gusset on the inside of the elbow to future proof.

    That's exactly what I was planning to do. Going to put in a small triangle there.

    When my buddy returns from his camping trip next week I'll have this welded up.
    Thanks all for the comments.

    looks like the break started on the edge of the "Heat Affected Zone", the border of where the metal turned cherry during the weld. the rounded crack parallel to the bead shows it.

    this is the area most prone to cracking at some point since it's properties have been changed by the heat of welding.

    When I bought my 450 had the foot lever was off. I didn't have the original so I got a replacement from ebay.

    Yeah I know I can get a replacement center stand on ebay easily enough. But given the failure, there's no guarantee that it won't happen again on the replacement stand as well since from what I can tell they are all welded the same.

    I rather repair this one with additional reinforcement gusset to make it a lot stronger.
