I had a 2014 1190 ADV R that I bought in march of 2021 with low mileage (~7900). The prior owner took immaculate care of the bike. The only problems he had were that the factory airbox design was deficient which required an aftermarket replacement and the fuel level float failed.
I sold the bike 16 months later after adding another 2500 miles on it. The front rim failed and wouldn't hold air without putting a tube in or tossing it for a replacement, then the TPMS screen deleted itself and couldn't be repaired by the dealership. After that upon changing the rear tire, that TPMS sensor snapped off and these were long out of stock at the time. Also during the time I owned the bike, KTM decided not to send out factory chains without master links, so you're supposed to remove the rear swing arm to put a new chain on (or, like the airbox, you go aftermarket).
Lingering in the back of my mind were also what happens if you break a chain (new engine), the frame cracking issues, and a monstrous propensity for clogging fuel filters at inopportune times. Pulling the fuel tank and dealing with oil changes were also unpleasant tasks.
Admittedly when I hopped on the bike for a test ride, I had to have it and was amazed with its performance, but pragmatism gets in the way sometimes.
