The KTM 390 Duke is 373.2 cc (22.77 cu in) displacement single-cylinder engine motorcycles made in India by Bajaj Auto, in collaboration with Austrian manufacturer KTM. The 390 Duke standard debuted at the 2012 EICMA show in Milan, Italy, and went on sale in India in June, 2013.T he RC390 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, which would make it the first Indian-made KTM motorcycle sold in the US market. Bajaj said eventually the bike will be sold in 80 countries worldwide.
In its home market, the 390 Duke's engine displacement and weight place it in the midrange size, 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 47 bhp (35 kW), 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 TheBloomberg TV India Autocar India Awards. IndianCarsBikes said that with a top speed of 160 km/h (99 mph) and a 0 to 100 km/h (0 to 62 mph) time of 5.5 seconds, the 390 Duke is the fastest motorcycle made in India as of January 2014.
