    I was about to change out the swingarm bearing and noticed this:

    The crack is ~50% of the circumference already and it goes completely through the material as I was washing the crud out of it and water drains out of the crack.

    As the crack is right at the oem weld I suppose that it should be possible to make a 'V' groove and TIG weld it back. I'll contact 'my' welder so he gives my an opinion.

    Good that I found it in time, could have been an ugly crash if the back tyre goes amok.

    BTW. It's my WR300 2010 with +600hrs on it.

    Cheers !

    Wow good catch on your part. Just went out and looked at mine no crack but no where near the hours. Might be able to find a reasonable one in ebay

    I have an appointment tomorrow with the welder, hope it's going well.

    I think the aluminum used for these swing-arms is to rigid/brittle, I already broke the chain-guard a few years ago and the tab was re-welded, good since. I did also found another post in this same forum with a swing-arm problem on the very same bike model but on a different location:

    http://www.cafehusky.com/threads/2009-wr300-cracked-swingarm-what-should-i-do.45094/

    Tomorrow will be a busy garage day, install new bearings to welded swingarm, linkage and mount everything back, want to go for a ride on Saturday ! :D

    Cheers.

    That's not breaking anytime soon!
    My son's Yamaha did the same thing. Luck of the draw.
