Ive have had an intermittent knock/ noise since about 5000 miles. I have called KTM "customer service" many times while the bike was under warranty. KTM told me to take it to the crappy KTM dealer near me. They never bothered to diagnosed the noise, and told me it was normal KTM noise. Now at 18k miles and not under it's stupid 1 year warranty its bad and in another shop. Its out if warranty now an KTM says they have no record of my calls and concerns/complaints.. even though i spoke directly to the KTM regional service manager multiple time, who assured me he would put notes it their internal system regarding my concerns about the noise. He also told me the notes he was making who cover me out of warranty if there was a problem with the engine. Now KTM says they won't cover it likely.. only 18k of mostly commuting. The current KTM dealer wgo has my bike says its likely a crank thrust bearing. Repair requires likely an engine overhaul.. thrust bearing failure is normally do to improper assembly and /or tolerances.. not commuting. I feel like i am being totally screwed hard by KTM.
