KTM 390 series

The KTM 390 Duke and RC 390 are displacement single-cylinder engine motorcycles assembled by Bajaj Auto, and KTM Asia Motorcycle Manufacturing, Inc. (KAMMI) for the Austrian manufacturer KTM. 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. 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. The RC 390 sport bike was presented at EICMA the following year. After the Duke's initial release, KTM CEO Stefan Pierer announced plans to export the 390 Duke to the US for 2014. Bajaj said eventually the bike will be sold in 80 countries worldwide.
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 to meet Euro IV emissions standards, and to incorporate new technologies such as ride-by-wire.
390 Duke.
In its home market, the 390 Duke's engine size and weight place it in the mid-range category, and it sells for more than three times the average price of a motorcycle in India. As one Indian reviewer put it "The 390 Duke may well be a simple little A2 license commuter for the European rider, but in the environs of Mumbai traffic, it's a proper rocket-powered scalpel." In the US market, the same motorcycle is considered small-displacement, lightweight, and relatively inexpensive. Similarly, the UK "Sunday Times" said, "Given that the 390 Duke weighs less than 150kg when it's full of fuel, you have to sit on it to stop it blowing away. It's as agile in traffic as a push-bike and whippet-thin," saying the bike was ideal for young riders with the A2 license, limited to , who would find it easy to ride and confidence-inspiring, while feeling "fast and sporty". Such a bike in the UK would also appeal to experienced riders looking for a practical and efficient commuter bike and runabout. The 390 Duke won the 2013–14 Jury's Choice Bike of the Year in The Bloomberg TV India Autocar India Awards.

2018 updates.
In 2018, KTM updated its Duke 390 with some minor changes, where it added a deflector plate on the left side of the chassis, to avoid exhaust heat near the riders leg. The Duke 390 in India gained new features and updates. The Duke 390 comes with a daytime running light, and is on Euro IV emission standards. 
RC 390.
A sport bike version of the 390 Duke, the KTM RC 390 was presented at the 2013 EICMA motorcycle show in Italy, though most details had been leaked a few weeks earlier. The 2014 model year road racing style bike has the same 373 cc engine making a claimed @ 9,500 rpm with a claimed weight without fuel of . With a fuel capacity , the wet weight would be . The frame of the RC is a different single piece trellis frame than the Duke, which KTM says is stiffer than the 390 Duke. The tires are Metzeler 110/70ZR17 front and 150/60ZR17 rear. Where the Duke has a steering head angle of 65° (or 25° rake), the RC's fork has a steeper 66.5° head angle (or 23.5° rake). The wheelbase is shorter than the Duke. The same ByBre disc brakes with ABS, and WP 43 mm front fork and rear shock are used on the RC 390.
KTM added a racing version of the RC 390, the RC 390 Cup for use by motorcycle racers ages 13 to 21 in the ADAC Junior Cup, a MotoGP event. The RC 390 Cup has no lights or mirrors, and no ABS to reduce weight, and an upgraded WP suspension, fully adjustable front and rear. The engine is detuned to a with a block-off plate, and has an Akrapovič exhaust.
