- Motorcycle gas tank developed a leak near where it bolts onto the frame while riding. KTM dealership did an inspection while they had bike from Aug 24 2024- April 3 2025. KTM determined itself not at fault and I had to pay $1,990.18 out of pocket for replacement. KTM kept faulty gas tank. -Gas tank leak is very dangerous to the rider as well as others because fuel is VERY flammable. 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. -No warnings before failure, tank leaked on Feb 22,2024
