At approximately 14,700 Miles, the motor on the bike shut off abruptly while riding at 60 mph down the road while negotiating a blind curve. The vehicle was catastrophically disabled with no warning sounds, lights, or codes and left me stranded in an area with limited cell reception and in a blind spot for approaching vehicles with no shoulder to safely park on. The bike had not yet seen its first scheduled maintenance interval (manufacturer recommends 18,000 miles) and had received multiple oil changes well before scheduled intervals. No aftermarket modifications were done to the engine, air, fuel or other pertinent systems. Upon disassembling the motor for inspection, there was substantial catastrophic damage to the cam shafts and cam followers. It was concluded by a BMW certified master mechanic that the failure was due to premature wear of the cam followers and cam lobes. The cam follower broke in the motor causing a jump in timing and ejection of valve shims. The force of the malfunction was severe enough to spin a cam lobe 90 degrees out of position on the shaft, bend valves, and other damage. Upon inspecting the air box and oil jets, these components appear in good form and do not appear to have contributed to this malfunction. Upon contacting KTM, I was denied any assistance and have had to facilitate these repairs on my own out of pocket expense (approximately 2500 dollars so far). KTM also denies accountability for what appears to be a design or parts flaw that has been happening to other motorcycles manufactured between 2020 and 2023.

The contact owns a 2020 KTM 790 Duke. The contact stated while riding approximately 30 MPH, the rear brake light failed to illuminate unless the brake pedal was fully depressed, not while slightly first applying the brake. The contact stated no warning light was illuminated. The contact had taken the motorcycle to a local dealer where it was diagnosed and determined that nothing could be repaired and that depressing the brake pedal with force was the only option to illuminate the rear brake light. The motorcycle was not repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 7,000.

The main rear shock shaft seal has failed on two separate occasions causing shock oil to spill all over the catalytic converter posing a huge risk for fire. On both failure instances the motorcycle was being transported on a motorcycle specific hitch rack on the back of my pickup truck. The first shock seal failure occurred when I was transporting the motorcycle to my local dealer for service and the temperature was 16 degrees Fahrenheit during transport. The second shock seal failure occurred when I was transporting the motorcycle to Moab for a riding trip and the temperature dropped down to -6 degrees Fahrenheit during transport. KTM completed the first repair under warranty, which only lasted about 9 months when the shock seal failed the second time. I had to pay nearly $600 to get the second failure repaired by a KTM dealer using KTM parts. Both shock seal failures caused shock oil to spill all over the catalytic converter posing a huge fire risk. At this point I seriously doubt the durability and safety of the shock and I'm considering replacing the shock with an aftermarket one that won't fail and cause a fire.
