Overview

Introducing the 2020 KTM 390 Duke, a striking contender in the naked bike category that perfectly balances agility, performance, and style. Renowned for its eye-catching design and spirited engineering, the 390 Duke is not just a motorcycle; it’s an experience waiting to be unleashed. This urban warrior is aimed at both new riders looking to make their mark and seasoned enthusiasts seeking a lightweight, nimble ride for daily commutes and spirited weekend jaunts. With its aggressive stance and a blend of modern technology, the 390 Duke has secured its place as a favorite in the competitive lightweight segment. At the heart of the 390 Duke lies a robust 373cc single-cylinder, four-stroke engine that showcases an impressive output of 44 horsepower at 9,000 RPM and a peak torque of 37 Nm at 7,000 RPM. This powerplant, complemented by a 6-speed gearbox, delivers exhilarating acceleration and seamless power delivery, making it a thrill to ride through twisting roads and urban landscapes alike. The advanced Bosch fuel injection system ensures precise fuel management, while the liquid cooling keeps the engine performing optimally, even under demanding conditions. With a lightweight design of just 149 kg (328.5 pounds), the 390 Duke offers an incredible power-to-weight ratio of 0.2953 HP/kg, allowing riders to carve through corners with confidence and ease. The 2020 KTM 390 Duke is packed with features that enhance both functionality and comfort. The steel trellis frame not only contributes to the motorcycle's lightweight nature but also ensures exceptional handling and stability. The WP suspension system, featuring upside-down forks in the front and a monoshock in the rear, provides ample travel (142 mm front and 150 mm rear) for a smooth ride over various terrains. Safety is paramount with dual ABS brakes—320 mm discs in the front and a 230 mm disc in the rear—offering superior stopping power and control. Additional features such as an electric starter and a sleek, modern design in eye-catching color options (black, orange, white) make the 390 Duke not only a practical choice but also a stylish statement on the road. **

Pros

  • Exceptional Power-to-Weight Ratio: With 44 HP in a lightweight chassis, the 390 Duke delivers thrilling performance and agility, perfect for nimble city riding or twisty backroads.
  • Advanced Suspension and Brakes: The WP suspension and dual ABS braking system provide excellent handling, stability, and safety for all types of riding conditions.
  • Modern Design and Features: The aggressive styling, along with modern technology like fuel injection and a digital display, ensures that the 390 Duke stands out in both looks and functionality.

Cons

  • Limited Passenger Comfort: The seat may be less accommodating for longer rides, especially for passengers, making it more suited for solo ventures.
  • Vibration at Higher RPMs: Riders may experience noticeable vibrations at higher RPMs, which can detract from comfort during extended rides.
  • Small Fuel Tank Capacity: While the 13.40-liter fuel capacity is adequate for urban riding, it may necessitate more frequent stops on longer excursions.
