The KTM 390 Duke and RC 390 are 399 cc (24.3 cu in)[2] displacement single-cylinder engine motorcycles assembled by Bajaj Auto, and KTM Asia Motorcycle Manufacturing, Inc. (KAMMI) for the Austrian manufacturer KTM.[1] The bikes were developed under a joint program of Bajaj and KTM engineers, in which the concept was developed in Austria, while everything else, including design and final product development, was done in India by Bajaj.[8] The 390 Duke standard debuted at the 2012 EICMA show in Milan, Italy, and went on sale in India and the Philippines in 2013 and in the US in 2015.[7][9][10] The RC 390 sport bike was presented at EICMA the following year.[11] After the Duke’s initial release, KTM CEO Stefan Pierer announced plans to export the 390 Duke to the US for 2014.[12][13] Bajaj said eventually the bike will be sold in 80 countries worldwide.[14]
Pierer said in December 2015 that KTM and Bajaj plan to replace the 125, 200, and the 390-series Duke and RC lines in 2017, based on all new platforms, in part tarnavo meet Euro IV emissions standards, and to incorporate new technologies such as ride-by-wire.[15]
