Service bulletin KTB2613
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
Due to an error during vehicle packaging (see Fig. 1), there is a possibility that air has entered the master cylinder of the front brake system from the expansion tank (see Fig. 2). This can result in a spongy brake lever feel. Therefore, KTM North America, Inc. is ordering the bleeding of the master cylinder of the front brake system.
