Overview

Introducing the 2017 KTM 390 Duke, a bold entry in the naked bike category that perfectly marries performance with style. Known for its aggressive design and lightweight construction, the 390 Duke stands out in the competitive entry-level market, making it an ideal choice for new riders and seasoned enthusiasts alike. With KTM's racing heritage embedded in its DNA, this motorcycle is built not just for commuting, but also for spirited weekend rides on twisty backroads, ensuring that every journey is nothing short of exhilarating. At the heart of the 390 Duke is a potent 373.2cc single-cylinder, four-stroke engine that delivers an impressive 44 horsepower. This spirited powerplant is paired with a six-speed gearbox that provides seamless shifting, allowing riders to harness the bike's full potential. The liquid-cooled engine features a Bosch EMS ignition system and a sophisticated fuel injection setup, ensuring smooth throttle response and efficiency. With a lightweight chassis tipping the scales at just 149 kg (328.5 pounds), the 390 Duke boasts a remarkable power-to-weight ratio of 0.2953 HP/kg, making it nimble and responsive in urban environments while still feeling stable at higher speeds. The 390 Duke is not just about raw power; it’s also equipped with cutting-edge features that enhance the riding experience. The steel trellis frame provides excellent rigidity and maneuverability, while the WP suspension—featuring a 43 mm upside-down fork at the front and a monoshock setup at the rear—offers 150 mm of travel for both ends, ensuring comfort and stability over various road conditions. The braking system is equally impressive, with a double disc setup at the front and a single disc at the rear, both equipped with ABS to enhance safety and control. Additionally, the striking color options of black, orange, and white make the Duke visually captivating, ensuring it turns heads wherever it rides. **

Pros

  • Lightweight & Nimble: At just 149 kg, the 390 Duke is exceptionally agile, making it easy to handle in tight spaces and during urban commutes.
  • Powerful Engine: The 373.2cc engine delivers robust performance, providing an exhilarating ride and impressive acceleration, ideal for both new and experienced riders.
  • Advanced Features: Equipped with ABS, high-quality suspension, and a sporty trellis frame, the Duke offers a perfect blend of safety and handling prowess.

Cons

  • Limited Passenger Comfort: The seat height of 830 mm may not suit all riders, and the limited rear seat space can be uncomfortable for longer rides with a passenger.
  • Small Fuel Tank: With a capacity of only 13.4 liters (3.54 gallons), fuel range may be a concern for long-distance travel enthusiasts.
  • Wind Protection: As a naked bike, the 390 Duke offers minimal wind protection, which can lead to fatigue on longer rides at highway speeds.
