I have used a GSXR 1100 swing arm on my bandit, It is about 3/8 inch wider at the front, I was able to cut an equal amount from each side and used the bandit bearings and spacer. If you can find a gsxr 750 swingarm that is braced, it may work. I have the 89 GSXR 1100 and a 89 gsxr 750
swingarms, but neither are braced.
