NTSB should recall
Based on no more information than given, with the picture of the fork broken part/failure, the NTSB should force BMW to do an immediate investigation and potential recall of all models using that part.
This is the scariest thing I've seen in a long time in so far as new motorcycle part failure.
This will cause death and injury to someone... our first victim was relatively lucky.
Covering this under warranty is not good enough.... any suspect parts need to be found and destroyed.
