Overview

Introducing the 2012 KTM SX 125: a thrilling entry into the world of supermotards that perfectly blends lightweight agility with spirited performance. Renowned for its off-road pedigree, KTM has crafted the SX 125 to appeal to both novice riders eager to hone their skills and seasoned enthusiasts seeking a nimble machine for urban adventures. Its striking black finish and aggressive lines are not just for show; they hint at the raw power and precision engineering that lies beneath the surface. The heart of the SX 125 is its vibrant single-cylinder, two-stroke engine, displacing 122cc to deliver an exhilarating 21.45 horsepower at your command. With a peak torque of 16 Nm at 9,750 RPM, this motorcycle thrives on high-rev excitement, allowing riders to experience the thrill of reaching a top speed of 115 km/h (71.5 mph). The responsive Dell’Orto VHST 28 carburettor ensures an energetic throttle response, while the 6-speed gearbox allows for seamless gear shifts. Coupled with a lightweight frame weighing in at just 115kg, the SX 125 offers an agile riding experience that’s perfect for navigating tight corners and urban landscapes. KTM has equipped the SX 125 with advanced features designed to enhance both performance and safety. The high-strength steel frame boasts a double trellis design that provides excellent rigidity while keeping the weight down. The 40mm upside-down hydraulic fork and a steel swingarm with a hydraulic monoshock offer a plush ride with ample suspension travel (260mm in the front and 270mm in the rear), ensuring stability and control over varied terrains. Additionally, the multi-plate wet clutch provides smooth engagement, making clutch control during tight maneuvers a breeze. With a fuel capacity of 10 liters, this motorcycle allows for extended rides without frequent stops, perfect for those who crave adventure. **

Pros

  • Lightweight and Agile: Weighing only 115 kg, the SX 125 is incredibly nimble, allowing for easy handling in both urban and off-road conditions.
  • Powerful Performance: The 21.45 HP engine delivers an exhilarating ride, making it perfect for those who enjoy spirited throttle response and high-rev excitement.
  • Advanced Suspension: With significant travel in both the front and rear suspension, the bike provides excellent stability and comfort even on rough terrain.

Cons

  • Limited Fuel Capacity: With only 10 liters of fuel capacity, longer rides may require more frequent refueling stops.
  • Kick Start Only: The traditional kick starter may deter some riders accustomed to electric start systems, especially in challenging conditions.
  • Single-Seat Design: The motorcycle is primarily designed for one rider, limiting its versatility for two-up riding experiences.
