1390 Super Duke R

The 1390 Super Duke R produces 190 hp from its LC8 V-twin in a 441-lb chassis that achieves a near 1:1 power-to-weight ratio — the most powerful supernaked KTM has produced, with WP Apex semi-active suspension and Brembo Stylema brakes that are genuinely necessary to contain the power. The extreme acceleration demands significant rider skill; this is a machine for experienced motorcyclists who have already mastered the middleweight naked class.
