Triumph Motorcycles America

On August 16, 2023, Triumph Motorcycles America submitted a safety recall report to the US National Highway Traffic Safety Administration (NHTSA) concerning all 2022 through 2024 Triumph Trident 660s and 2022 through 2024 Triumph Tiger Sport 660 motorcycles.

The reason for the recall is a potential problem with the engine stalling due to an obstruction in the hose and incorrect sensor information being sent to the engine control unit (ECU). This issue could lead to unexpected engine stalls, heightening the risk of crashes.


Safety Recall

Triumph Motorcycles America’s records indicate that approximately 7,541 motorcycles could be affected, covering 100 %of the models in question. Owners of 2022 through 2024 Trident 660 or Tiger Sport 660 motorcycles are advised to arrange for service at their earliest convenience due to this recall.

The problem arises from the possible blockage of the manifold absolute pressure (MAP) hose. Consequently, the MAP sensor might record inaccurate data, which is then relayed to the ECU. As the ECU uses this data to adjust the fuel/air mixture, inaccurate information could lead to unstable engine idling and potential stalling.
