Lets just wait to find out what happened before making unfounded comments about what caused this person to die. While witnesses said he took off at a high rate of speed, sport bikes naturally accelerate much faster than do cars. Speed wobble? He may have hit something slick on the roadway or even hit a rock or something else that caused the bike to wobble. I have been riding for almost 52 years and have seen wobbles from all kinds of  situations. I knew a guy in 1979 who was just going into his driveway after doing a test ride. He was only doing about 5 mph when the bike went over. He was not wearing a helmet and his skull got crushed when his head hit the curb. We do not know what was the key factor in this mans death. My heart felt condolences to the mans family and friends.
