As the entry-level model in KTM's competitive lineup, the SX 125 is tailored for both newcomers looking to make their mark and seasoned riders seeking a lightweight machine for urban adventures or track days. With its bold aesthetics, striking color options like Red Flash and Yellow Stark, and the unmistakable KTM pedigree, this motorcycle is ready to dominate the streets and circuits alike. At the heart of the SX 125 lies a potent 124.2 cc single-cylinder engine, delivering a thrilling torque of 11.2 Nm at 8,000 RPM, ensuring that every twist of the throttle translates into exhilarating acceleration.

The lightweight twin-tube steel frame offers exceptional rigidity while keeping the total weight at a nimble 134 kg (295.4 lbs), allowing for agile handling in any situation. The suspension setup, with an upside-down fork at the front and a monoshock at the rear, provides a generous travel of 240 mm and 210 mm respectively, ensuring superior comfort over rough terrains. Coupled with responsive brakes—a 300 mm disc up front and a 220 mm disc at the rear—the SX 125 delivers confidence-inspiring stopping power, making it as safe as it is thrilling. **
