KTM 390 series
The KTM 390 Series are a range of single-cylinder engine motorcycles assembled by Bajaj Auto, and KTM Asia Motorcycle Manufacturing, Inc. for the Austrian manufacturer KTM. There are currently six bike models which 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 six models in the line up are the road worthy 390 Duke, RC 390 and 390 SMC R and the dual purpose 390 Enduro R, 390 Adventure R and the 390 Adventure X.
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 tarnavo meet Euro IV emissions standards, and to incorporate new technologies such as ride-by-wire.
In 2024 KTM started the transition from the original motor to the new LC4c motors. The new 390 SMC R, Enduro and Adventure models began introduction into the 2025 line-up.
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.
