Has anyone considered calling the US KTM reps?
Yes, they want to sell machines, yet I believe they will give you the skinny on this topic and tell you that you should not rely on the KTM EXC transmissions and motors for long distance trips with out multiple and frequent maintenance intervals..
At least that was told to me by a qualified KTM shop owner and their mechanics (they have more to gain by lying then anyone).
Just an idea.
