Seems like every KTM I've owned with electric start does not want to start if you initially press and hold start button; especially if cold and been sitting more than a day or two. But, if you turn on the ignition, allow the fuel pump to build psi, then just bump the starter for a mere second or less...than pause a second...than press the start button it will crank right up. Just seems to be one of those quirks with a KTMs. If you have a lithium battery, when parked at home, best to have a lithium specific battery maintainer attached 24/7/365. I have a Shoai Lit battery and maintainer and no issues starting, even when cold. My maintainer died out-of-warranty and Shoai replaced it at no cost. That's customer service!
