I own a 2016 model SD-GT purchased new in the USA in 2017. My dealer told me there is a two year warranty on the bike but I was never able to find this written for a 2016 bike on the KTM web site or in any of their literature. I've seen that warranty offered on 2017 bikes but not my 2016.
After leaving a couple of messages with KTM USA Customer Service phone number in Murrieta, California (951-600-8007) I got a call today from them telling me that my bike has 24 months or 24k miles warranty on it. I got the person who called me to cross check this with my Vehicle Identification Number to be sure, and that appears to be correct.
