2016 KTM 690 Duke / Duke R
KTM’s engineers punched out the 690 engine ahead of MY2016 and shortened the stroke for more power. They apparently did well enough that the “new” engine is, so far, a direct carryover all the way into MY2019. In spite of its dirtbike origins, the Duke family has abandoned all but the vestigial details in favor of a naked-sportbike build that brings top-shelf performance to the supersport size bracket. A modern electronics suite rounds out the “R” variant. The base 690 Duke comes without most of the suite in its stock configuration, but comes with said electronics as part of its optional “Track Pack” equipment package.
