Triumph Tiger Sport 660 Recall 23V583: Obstructed Air Hose Can Cause Sudden Engine Stall

NHTSA campaign 23V583, reported August 16, 2023, 7,541 vehicles potentially affected.

What this recall means for you

Certain 2022-2024 Triumph Trident 660 and Tiger Sport 660 motorcycles may have an obstruction in the manifold absolute pressure (MAP) hose. This can cause the MAP sensor to give incorrect air pressure readings, leading the engine control unit to adjust the air/fuel mixture based on inaccurate data.

The result can be an engine stall while riding, which increases the risk of a crash. If you own an affected model, stop riding it until the repair is done if you notice any unusual running or stalling, and contact an authorized Triumph dealer.

The replacement of the MAP hose is free of charge at an authorized dealer. Owner notification letters are expected to be mailed August 31, 2023. You can also contact Triumph customer service at 1-678-854-2010 (recall SRAN 609), and check your VIN for open recalls.
