2015 KTM RC 390, FeaturesFrame - Solid Technology: Visually similar to the lightweight and approved Duke steel trellis frame, the orange painted frame has been modified to better fit the supersport ergonomics and dynamics. The increase of the steering head angle to 66,5 degrees results in a shorter trail, shorter wheelbase and increased ground clearance. All these modifications release the complete racing potential of the RC and guarantee quick, agile and playful handling.Swing Arm: The light alloy swingarm with directly linked WP shock absorber excels by providing extreme torsional stiffness and outstanding tracking stability.
