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 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.
