Owner-reported complaints filed with NHTSA, grouped by component

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

2018 KTM 690 Duke fuel tank shape has warped and the fuel filler neck gasket no longer seals the filler neck to the tank so that fuel spills out the top of the fuel tank. This same issue was addressed for the 2016-2017 model year KTM 690 Duke under NHTSA Campaign Number 17V388000. The result of this fuel leak is a potential fire hazard that could result in injury or death. This problem has not been confirmed by a dealer or independent service center and has not been inspected by the manufacturer, police, insurance representative or others. There were no warning lamps or messages associated with this problem. The main symptom of the problem is a strong fuel smell when near the motorcycle.

The plastic fuel tank has warped at the bottom interface where the fuel pump assembly sits. As a result, fuel leaks between the fuel tank and gasket (which is no longer sealed against a flat surface). The fuel pump assembly sits immediately above the engine. Fuel that leaks will drip onto the engine and may ignite. Fuel ignition presents a significant hazard to the rider. This issue appears to be related to recall campaign number 17V388000, which affects the 2016 and 2017 models. This recall addressed a warping plastic tank that resulted in the fuel filler neck not sealing. My understanding is that there are very little to no material differences between the 2016-2017 and 2018 models, and therefore the problem of a warping plastic tank would be shared among the model years.
