I saw in some youtube video’s they told that duke is some more aggressive in acceleration & in a video I saw head to head straight road racing duke 390 was the winner.
KTM RC 390 is faster in acceleration than KTM 390 Duke. Transmission is very smooth in RC 390 which helps this bike to reach 0-100 km/hr in just 5.70 seconds. While, Duke 390 covers this distance in 7 seconds. While engine used in this bike is a water cooled, 1-cylinder, 4-stroke 373.2cc. Both the bikes are mated to claw-shifted 6-speed manual transmission.
