Run trough the OC-hall of wisdom and read the service manual in your free time. The mechanical side ain't that complicated at all. And IF it fails it's easy to fix aswell.
Just check all the small imperfection's on the bike and the thing wil be bulletproof. This is my 5th KTM and i can say you won't be dealing with 'Italian quirks'.
None of my KTM's have left me stranded yet. It aint a Japanese bike but it aint as boring to ride as a Jap bike either.
But be warned, the thing wil become an obsession!
