Owner report 11622006 · 2024-10-25 (October 25, 2024)
Coming to a stop the engine just quit, as if I turned the ignition switch off. The dash was also blank. I turned the switch to the off position and then back to the on position, and it started as normal. I have read about this same sort of thing happening to numerous other riders of this bike. Triumph needs to have a recall to fix the glitch in the ecu.

Owner report 11653225 · 2025-04-07 (April 7, 2025)
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 show…

Owner report 11660245 · 2025-05-11 (May 11, 2025)
I had been riding on a road for about 15 minutes at speeds ranging from 40-50 mph. As I came to a stop sign, I downshifted and used engine braking to assist the brakes in slowing down. After I downshifted from 3rd to 2nd gear, the engine quit and all dash lights illuminated. I pulled the clutch, pressed the starter button as I coasted, and the engine re-started. The engine ran fine before and after the incident. This happened at approximately 1,600 miles. This is the second time this happens under similar conditions: downshifting from 3r…

Owner report 11684669 · 2025-09-03 (September 3, 2025)

Owner report 11742822 · 2026-06-08 (June 8, 2026)
Riding on a highway at about 70 mph, the bike sputtered so I got into the right lane, pulled in the clutch and the bike lost power so I coasted onto the shoulder. The bike has not started up since--I was towed home. I saw no warning lights in advance. The bike was serviced after 600 miles and now has 5200 miles. Had I been in the far left lane, I may not have been able to safely get off the road in heavy fast-moving traffic. Cause of problem: UNKNOWN. I'm assuming I'll have to have the bike towed to the dealer for repair.
