TRIUMPH Complaints

When I slow down my bike and hold in the clutch, the engine will cut off. This can happen as I'm coming to a stoplight or it has also happened during turns which is extremely dangerous on a motorcycle. I have taken my bike to the dealer and they supposedly fixed the problem, but fast forward 7 months later to this month and the problem has resurfaced even more severe than before. It happens every day I ride the bike and I am a daily rider.

My motorcycle began stalling when I pulled in the clutch and braked when approaching stops or when moving through slow speed turns. As time went on, it became more and more frequent. At least, once per ride. In December 2022, I took my Trident in for its annual service and mentioned the stalling to the technician. He said they would take a look at it and see what's up. When I picked up my bike, they said that they did not experience any stalling during their test ride after the service. Because they were not able to replicate the issue, no work was done. But they said to bring it back if the problem continues. The problem continued. In January 2023 and it was happening several times in a single ride. On a bad day, it would stall at every light or stop sign I'd hit, making the bike feel unsafe and un-rideable. It would die mid-turn causing me to almost fall over with traffic behind me. Then I started experiencing some trouble starting my bike when the engine was cold. I'd pull in the clutch, hit the ignition switch, and the engine would turn over before promptly dying. So I took it back to the dealer and this time they reflashed the ECU, thinking there might be some kind of bug there. I rode the bike home and it continued to stall. I returned to the dealer again. As it turns out, the MAP sensor and the MAP sensor hose was mucked up with oil and that there was also oil inside the airbox. These parts were replaced. Since then, the stalling issue has been resolved. But there are various forums online with riders providing anecdotal information about the stalling issue returning later on. https://www.trident660.com/index.php/topic,255.0.html

I was operating the motorcycle in a typical fashion and the engine died several times. I had to try to find a safe spot to pull over and restart the motorcycle. After restarting it twice it just died again as soon as the clutch was pulled in. The motorcycle is practically new, less than 1000 miles on it. I did some research online and found that many many other people ran into the same issue and Triumph is aware. There is a defect with the MAP sensor and restrictor in a hose that will cause this in all of the 660 cc engines. However, there are no recalls and this could get someone killed.

Over the course of 16 months of ownership, I have now scheduled a second appointment to have my rear brake lines flushed and refilled under warranty. This can be inspected if necessary. The reason for scheduling this maintenance is the brakes will "fade" over the course of several weeks to months due to an admitted manufacturing/ assembly defect where there are air bubbles inadvertently allowed into the rear ABS system. This defect makes emergency braking nearly impossible as only the front brakes work to their potential. The dealership I have been conducting business with has been very forthcoming with this being a known issue for this year and model. There are no warning lamps/ messages when the problem occurs. The only indication is a brake pedal that feels progressively softer when applying pressure to stop.

Triumph has issued a recall for rear brakes failing that does NOT fix the issue. Myself and many other owners are experiencing multiple rear brake failures after several recall attempts. I have had my rear brakes fixed by recall 3 times, including an ABS modulator replacement and my brakes are going bad again. This is an extreme safety issue and someone is going to get seriously injured.

The contact owns a 2017 Triumph Bonneville. The contact stated that while riding at an undisclosed speed, the motorcycle lost motive power while making turns. The motorcycle was taken to the dealer, where it was diagnosed that the wiring harness was faulty and needed to be replaced. The motorcycle was then taken to an independent mechanic, who connected a split wire from the wiring harness; however, the failure recurred. The motorcycle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 3,500.

My Triumph Rocket 3 loses pressure to the rear brake and stops working. Triumph currently has a recall and a service bulletin for Rocket motorcycles, however it does not work. Approximately every 4-6 months i must bring my motorcycle to the dealership to have the rear brake bleed. it will work for a short while then stop again after a couple months

The wire harness has torn under ignition. The traction control stops working, needles bounce, and at times will not start. The wire pulls when the handlebars are turned to the right. I brought it to Moto primo to have it fixed. There was a recall for this issue and they want to charge me over $700 for an issue that they are obviously aware of. I had the bike in AZ over last winter and brought it in on a different recall. Moto primo said that the dealer looked at the issue in Phoenix but did not replace the part. They told me that I have to deal with the dealer in Phoenix which is 1800 miles away. This is a very dangerous thing. The needles initially started bouncing when I was driving from Phoenix to Minneapolis. It was doing it again when I was in MN. I went to blogs and read that there were issues where the wires stretch and tear when the bars are turned to the right. I looked at the wiring and it was torn and stretches when the bars were turned.

The the front brakes are soft and slow to engage when pulling the brake lever. However, when pulling the lever immediately afterwards, the brakes engage quickly and firmly. After a short period of time without engaging the front brakes, pulling the lever again results in soft and slow engagement. Slow and soft engagement of the front brake is a clear safety issue and may result in an accident. The problem was confirmed by an independent mechanic, Cycles of Silver Spring in Silver Spring, Maryland. The vehicle has been repeatedly inspected, and brake fluids have been replaced three times. The issue is resolved for a short period but then returns.

My bike has the same issue as many other Triumph Thruxton 1200Rs with a soft initial brake application. The first time that the brakes are applied, there is extra travel and a softer lever feel. After the first application, a subsequent application has a shorter travel. I reported this to a dealer early on, and they stated that they did not find anything out of spec. This is not a normal thing as none of my other motorcycles have ever had this issue. The brake system is supposed to be consistent from first to subsequent brake applications.
