2017: “Earlier today I was riding my 2017 Triumph trophy se motorcycle on a city street when the bike suddenly shut off completely in the middle of a left turn. I was able to get to the side of the road and discovered that the engine and all electrical systems would shut of whenever the handle bars were turned to the left. It acts exactly as though I had turned the ignition key to the off position. This is obviously a major safety issue. If a car had been behind me when this happened, it could have resulted in a serious accident. …”
