What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The fuel tank swells in size so much that it cannot be reinstalled to the bike using the factory mounting bracket. It had to be modified, and now I might have to drill a hole further back in the frame to fit my tank back on.
The fuel tank has developed a leak. The leak appears to be a manufacturing defect and is coming from a threaded fitting. The tank was not mechanically damaged in any way.
Fuel leaks from tank where low fuel level sensor is fastened to tank. The sealing o-ring on fuel level sensor does not contact the mating surface on the plastic tank due to a dip or low spot in the mating suffice.
Fuel tank deformed and leaked about 2 gallons of gasoline in my closed garage - 2008. Ktm north america instructed bike be taken to dealership for evaluation - ellicott city motorsports visually inspected, called ktm/na who instructed me to "try loctite 518 sealant".
The fuel tank on my 2006 ktm 950sm motorcycle failed, causing a gasoline leak which could have resulted in a fire, crash, and/or possible death or injury. The location of the failure is at the area where the fuel sensor plugs into the side of the tank. The plastic around the sensor disintegrated, causing the leak.
