999 Bip Steel Subframe Fail?

Discussion in '749 / 999' started by 900streetfighter, May 5, 2017.

  1. i know the alloy mono subframes fall apart on a regular basis but has anyone had or know of a steel bip subframe failing. Im planning big 2up trip and a post on another forum has said they can but I would like to confirm before employing a welder.
     
  2. Not heard of any...
     
  3. ..frame x-ray'd for possible signs of fatigue?
     
  4. Mine failed but on the middle exhaust supporting part, the thin metal plate that the exhaust bolts too, was told by welder it just was a bad weld and unlucky it cracked on the weld edge. It was nothing to do with weight i.e. Passenger or not and was still rideable even with a passenger. Don't worry enjoy your trip
