I have no clue what caused it. That is the aluminum monoshock swingarm off my '83 GS750ED. It is cracked at the pivot point where it attaches to the frame. The opposite pivot point also has a hairline crack, but not as bad as the one pictured.
Don't know how long it has been that way either as it was hidden under the rubber chain buffer and could only be seen after removing the buffer and being degreased. That swingarm is pretty lightweight, I am now wondering if it is up to the task of handling sticky radials and 100+ hp.
I am having it welded/braced and will see how it comes out. Also, mocked up the '92 GSXR750 arm last night. It will fit in the frame pivot area without much fuss but is much wider, the footpeg attachments must be cut off the frame and rerigged further outward to clear the arm.
I am gonna wait and see what the '83 arm looks like after being repaired before doing any surgery on the GS frame.
