The VIN makes it within the range of "possibly" being an SS.
The PR is probably just some one tampering with the plate. The longer these bike have been out in the public the more butchering has been done to these bikes.
The NOC with the factory records is the ONLY way I would accept it has any connection with a production racer except factory original paperwork.
The bow on the backbone tube is in all commandos. Only the amount varies, I have never seen one without it, since they all happen from shrinkage from welding the crossbar during original manufacture of the frame.
