What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Luckily no fire, was stranded 2 hours away from home where I waited for fuel to fully empty on the floor before towing home. -KTM owners on online forums have experienced same leak on this model bike, KTM dealerships should have documentation on multiple reports of faulty gas tanks.
Seems as if the gas tank has expanded and caused the rear fender plastics to pop out of the clips and can see fender body gaps larger than before.
The contact stated that the failure was caused by the ethanol fuel used to operate the motorcycle and was concerned that the fuel tank might eventually develop cracks, causing a fuel leak. The vehicle was not yet repaired. The local dealer was notified of the failure. The manufacturer was not contacted.
