Introducing the 2023 KTM 125 Duke, a stunning entry into the naked bike segment that perfectly blends raw performance with agile handling and futuristic aesthetics. Renowned for its lightweight design and nimble characteristics, the 125 Duke is a prime choice for both novice riders looking to hone their skills and seasoned enthusiasts seeking a reliable urban companion. With a striking black and orange color scheme that pays homage to KTM's racing heritage, this motorcycle demands attention on the road while delivering an exhilarating ride that’s both spirited and engaging. At the heart of the 125 Duke lies a robust 125cc single-cylinder engine that produces a peppy 15 horsepower and 12 Nm of torque. This powerplant, featuring a state-of-the-art electronic fuel injection system, ensures snappy throttle response and impressive fuel efficiency, boasting a remarkable 2.42 liters per 100 kilometers—equivalent to around 97.20 mpg. Paired with a smooth 6-speed gearbox, the Duke offers a thrilling riding experience whether you're weaving through city traffic or enjoying a weekend ride on winding roads. The liquid cooling system maintains optimal engine temperature, allowing riders to push the limits without overheating, while the lightweight steel trellis frame enhances both stability and maneuverability. KTM has equipped the 125 Duke with an array of features that elevate its status in the naked bike category. The WP Apex suspension setup provides exceptional handling, with front travel of 142 mm and rear travel of 150 mm, ensuring a comfortable ride over various terrains. Safety is paramount, and the bike features advanced ABS technology on both the front and rear brakes, providing reliable stopping power with a single disc setup. The electric starter adds convenience, while the seat height of 830 mm caters to a wide range of riders, making it accessible for many. With a fuel capacity of 13.40 liters, the Duke is ready for longer rides without frequent stops, making it a versatile option for commuting or weekend adventures. **

Pros

  • Lightweight & Agile: At just 139 kg, the 125 Duke offers excellent maneuverability, making it ideal for urban settings and tight corners.
  • Impressive Fuel Efficiency: The bike’s fuel consumption of 2.42 liters/100 km means fewer stops at the pump, allowing longer rides between fill-ups.
  • Advanced Suspension & Braking: The WP Apex suspension and ABS-equipped brakes ensure a smooth ride and confident stopping power, enhancing rider safety and comfort.

Cons

  • Limited Power for Highway Riding: While perfect for city commuting, the 15 HP output may feel underwhelming for extended highway trips or steep inclines.
  • Minimal Storage Options: The naked bike design lacks integrated storage solutions, which may require additional accessories for carrying gear.
  • Seat Height: Though accessible for many, the seat height may pose challenges for shorter riders, affecting overall comfort and control.
