2024 Triumph Speed 400 Engine Problems

“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.”

“I was making a right turn at an intersection while in 3rd gear with the clutch engaged, and the motorcycle stalled. I was able to restart the motorcycle while executing the turn and completed the turn without incident. Failure to do so would have put myself at risk from oncoming vehicles through the intersection. When this has happened the low oil pressure indicator illuminates. The oil sight glass shows oil level to be at max. I use ExxonMobil 93 fuel. …”

“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.”

“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 3rd to 2nd, and using engine braking. …”

“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. …”
