What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
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.
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.
The contact noticed that gasoline was leaking between the fuel pump and fuel tank at the rear center underside. The gasoline started to form a puddle in the driveway. The contact stated there was no warning light illuminated. The contact had not taken the vehicle to a dealer or independent mechanic.
This presents an extreme fire risk. There is an active recall (NHTSA Campaign Number: 17V388000) for 2016-2017 production of the same model. This recall should be expanded to include the 2018 model year. I removed a few parts and inspected the filler neck to tank connection and found visible warpage.
Tl* the contact owns a 2018 ktm 690 duke. The contact stated while he was walking backwards to turn the motorcycle around with the gearbox in neutral and the clutch lever engaged, the motorcycle was started and the clutch failed causing the motorcycle to accelerate inadvertently.
