The vin # is stamped on the frame at the steering colum. It is this way with all bikes as far as I know. There is no way to rig that one, and it matches the title, and the title is no salvage. It was bought at a local dealer, and there used to be a lean on the bike from the second owner that he had paid off. I have seen the documents to this.
Being that said. I think that the 1st owner did not want it there for some reason.
As a side note, the 2000 ZR7 I had, had a sticker, and that was it. It came partially off because gas got on it.
