“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. …”
NHTSA complaint #11266466, filed 2019-10, 16,700 miles“I was backing up my motorcycle (while it was running) and as I turned the handlebars to the right, all electrical shut off (the engine included). This continued to happen every time I turned the handlebars to the right, and got progressively worse, from only happening when turning full right to barely to the right of center, but I was able to make the ride home, about 100 miles, as long as I didn't make a right turn! Fortunately, on a motorcycle, most turns can be made by leaning the bike. Anyway, the problem turns out to be the wiring coming out of the ignition switch. …”
