This, along with an already sterling reputation as being a THE CORNER ROCKET and an aggressive seating position, means the KTM 390 DUKE sets the standard when it comes to energetic NAKED machinery.ALL-IN AGILITYFrameThe design features a 2-piece construction composed of a steel trellis main frame with a pressure die-cast aluminum subframe. The rear shock absorber is mounted off-center to allow for the large airbox which allows for the lower seat height and, at the same time, adding to the DUKE's aggressive stance. Not only designed for looks, the primary objective of the frame design is to enhance vehicle dynamics by augmenting torsional rigidity, nimble agility, and enhanced feedback from the chassis.
