Overview

Introducing the 2012 KTM 125 Duke, an exhilarating entry in the naked bike category that perfectly embodies the spirit of street riding. With its bold styling and lightweight design, the Duke stands out in a crowded marketplace, appealing to both novice riders eager to embrace their first motorcycle and experienced enthusiasts seeking a nimble, urban companion. This bike combines the thrill of performance with the practicality of daily commuting, making it an ideal choice for those looking to conquer city streets and twisty backroads alike. At the heart of the 125 Duke is a peppy single-cylinder, four-stroke engine that displaces 125 ccm and delivers a spirited 15 horsepower. This powerplant is engineered for fun, offering an engaging ride without overwhelming new riders. The six-speed gearbox allows for smooth gear transitions, enhancing the overall performance, while the liquid cooling system ensures optimal engine temperature even during spirited rides. The lightweight frame, weighing in at just 125 kg (275.6 pounds), combined with a power-to-weight ratio of 0.1200 HP/kg, ensures that the Duke is not only agile but also provides confidence-inspiring stability and responsiveness on the road. The 125 Duke is packed with features that elevate the riding experience. Its tubular space frame is not only robust but also powder-coated to withstand the rigors of everyday use. The WP suspension with 150 mm of travel at both the front and rear delivers a plush ride, absorbing bumps and ensuring stability when navigating urban obstacles. Safety is paramount, and the Duke is equipped with double disc brakes at the front and a single disc at the rear, providing strong stopping power. With an electric starter and a seat height of 810 mm, this bike is designed for ease of use, making it accessible for riders of various heights. **

Pros

  • Lightweight and agile, making it perfect for urban environments.
  • User-friendly power delivery, ideal for new riders while still entertaining for experienced ones.
