Here are some pictures of what happened to one of the linkage rods on my 98KX250 when the lower shock mount bolt backed out. What's interesting is I never noticed it while riding. Thank goodness I happened to spot it before it was too late. This makes a good case for the use of loctite. :eek:
I had the exact same thing happen on my CR 125. Except my piece was snapped in two. Luckily I found a guy on line who cracked his frame and he is parting out his bike.
