Overview

Introducing the 2013 KTM 125 Duke, a striking entry in the naked bike category that perfectly embodies the spirit of street riding. Designed for both novice riders and seasoned enthusiasts alike, the 125 Duke offers a blend of agility, style, and performance that makes it a standout in the urban jungle. With its sharp styling, minimalist aesthetic, and lightweight frame, this motorcycle is tailored for those who crave a nimble ride through city streets, while still retaining the essence of KTM's racing heritage. At the heart of the 125 Duke lies a robust single-cylinder, four-stroke engine with a displacement of 125.00 ccm. Producing 14.75 horsepower, this powerplant is engineered for performance and efficiency, delivering spirited acceleration and smooth power delivery. The combination of a six-speed gearbox and a wet multi-disc hydraulic clutch ensures seamless gear changes, allowing for a dynamic riding experience. The liquid cooling system keeps the engine running optimally, making the bike not only fun to ride but also reliable for daily commutes. With a power-to-weight ratio of 0.1180 HP/kg, the 125 Duke is agile and responsive, encouraging riders to carve through corners with confidence. The 2013 125 Duke is equipped with advanced features that enhance both safety and comfort. The tubular steel frame, powder-coated for durability, provides a solid foundation for the bike, while the WP suspension setup—featuring both front and rear travel of 150 mm—ensures a smooth ride over varied terrain. Stopping power is provided by a 280 mm front disc with two-piston calipers and a 230 mm rear disc with a single-piston caliper, delivering reliable braking performance when you need it most. The electric starter adds convenience, and the stylish color options of black/grey and black/orange allow riders to express their personality. **

Pros

  • Lightweight and Agile: At just 125 kg (275.6 lbs), the 125 Duke is incredibly easy to maneuver, making it ideal for urban riding.
  • Excellent Suspension Setup: The WP suspension provides a comfortable ride while maintaining stability and control, even on rough surfaces.
  • Strong Performance for Its Class: With 14.75 HP, the 125 Duke delivers a lively performance that makes it fun and engaging to ride.

Cons

  • Limited Power Output: While suitable for beginners, more experienced riders may find the power output on the lower side for highway cruising.
  • Minimal Wind Protection: As a naked bike, the 125 Duke lacks wind protection, which might lead to fatigue on longer rides.
  • Small Fuel Tank: With a capacity of only 10.50 liters (2.77 gallons), fuel stops may come more frequently on longer journeys.
