Here is a 1980 Suzuki RM100 I am rebuilding. The bike has an RM125 swingarm which may not work?? The shock mounts are slightly more rear mounted which may sag the rear. I will see after the bike is finished. I have the stock RM100 swingarm so I can switch if needed. I was under the assumption that the frame size matched the RM125 model but it appears to be a smaller framed bike? Is this the case???
