Example complaints

“The fuel tank on my 2016 Ktm 690 DUKE does not seal around the fuel door. Gas can spill out of the top of the tank, especially with a full tank. The fuel tank is also open to the atmosphere causing vapor to enter an enclosed parking garage. The tank appears to be warped at the area where the fuel door is mounted to the tank. The gas smell has always been present since purchasing the bike but I did not find the problem until 6 months later. The dealer was notified and they said to immediately bring the bike in. …”
NHTSA complaint #10957132, filed 2017-02, 3,300 miles“Fuel tank (plastic) is warped and leaks fuel and fuel vapor near the upper flange seal. Tank was replaced once by Ktm under warranty with the same plastic tank as the original, the problem is less but persists, fuel smell is still coming from the tank, fuel vapor is still escaping. I know of two other 2016 Ktm 690 DUKE motorcycles with this same exact problem and I believe this fuel tank failure is due to poor fuel tank design. This is both a safety issue and an environmental issue. A recall on this fuel tank should be considered.”
NHTSA complaint #10969018, filed 2017-03, 1,400 miles“There is a deformity where the fuel tank connects with the fuel lid/cap. It appears wavy which doesn't allow for a proper seal between the tank and lid. When the tank is full and the motorcycle is tilted side to side it sloshes the fuel and fuel leaks out of the tank. Fuel leaks when turning on the roadway.”
NHTSA complaint #10966146, filed 2017-03, 700 miles“Vehicle's fuel tank has warped around the filler neck. This causes gas to leak out of the top when full. Vehicle needs to be in motion of this to happen as fuel will slosh around. Fuel tank is made of plastic and will need replacement to fix the issue. This is a safety hazzard.”
NHTSA complaint #10966292, filed 2017-03, 1,600 miles“2016 Ktm 690 DUKE plastic gas tank is swelling and deforming. This is causing a gapping issue with the plastics on the bike as well as around the fuel door area which allows fuel and fuel vapor to leak when the bike is rocked during operation or when the bike is stationary.”
