I picked up a rough ST90 a couple years ago. The guy said it was solid and the frame was in good shape. I didn't get any great pictures but it was cheap. I drove just over an hour to go pick it up and when I got there I noticed rust holes in the frame. I knew I could make money on ebay with what parts were good so I bought it anyway. Now you know the story... Is the rust in the frame fixable ? or just junk? I don't want a show bike, just a rider.
