KTM 690 Duke

10,450

Two decades ago, the original Duke was nothing short of revolutionary. KTM’s first single-cylinder street bike grew into a cult classic, adding extreme fun to a raw and radical concept. Today’s 690 DUKE stays faithful to its ancestor’s ways, but adds future-proof refinements: impressive smoothness, sophisticated electronics, improved ergonomics and tons of grunt. This firmly cements the world’s strongest single-cylinder production motorcycle at the cutting edge of engineering. Long live the Duke!
