NHTSA Complaint #11653225 — 2024 TRIUMPH SPEED 400

The motorcycle cuts out when slowing down—engine just dies, but all the electrical stays on. This is a brand-new bike with only 500 miles on it. It happened while I was riding, and I suddenly had no power. Luckily, I was on the right side of the road and managed to coast to the shoulder safely, but it could’ve gone a lot worse. There were no prior warning lights. I scheduled an inspection, but the earliest appointment isn’t until later this month. In the meantime, I did some digging—this doesn’t seem like an isolated issue. A quick search shows a lot of riders are having the same problem. It’s not just a software bug—forums, independent sites, even YouTube videos are all showing the same failure.
