Overview

Introducing the 2013 KTM SX 125, a thrilling entry into the super motard category that perfectly balances lightweight agility with robust performance. Renowned for its exceptional engineering and race-ready capabilities, the SX 125 is a favorite among both novice riders and seasoned enthusiasts alike. With its striking black design, this motorcycle not only captures attention but also embodies KTM's commitment to high-quality performance and innovative technology, making it an attractive option for those eager to carve their way through city streets or tackle winding country roads. At the heart of the SX 125 lies a spirited single-cylinder, two-stroke engine with a displacement of 122 cc, capable of producing an impressive 21.45 HP at 9750 RPM. The engine's design, with a compression ratio of 12.5:1 and a well-tuned Dell’Orto VHST 28 carburettor, ensures that it delivers a thrilling ride, reaching a top speed of 120 km/h (74.6 mph). Riders will appreciate the responsive torque of 16.00 Nm, providing exhilarating acceleration that feels both powerful and manageable. Coupled with a 6-speed gearbox and a lightweight frame weighing in at just 115 kg (253.5 pounds), the SX 125 offers a dynamic riding experience that enhances maneuverability and control. The SX 125 is equipped with a robust set of features that elevate its performance and rider experience. The high-strength steel frame, characterized by its double trellis beam and detachable seat frame, contributes to superior handling and stability. Suspension is equally impressive, with a 40 mm upside-down hydraulic front fork and a hydraulic monoshock in the rear, providing 260 mm and 270 mm of travel, respectively. Braking is handled by powerful single disc setups at both the front and rear, ensuring reliable stopping power when needed. Additional highlights include a kick starter for simplicity and a comfortable seat height of 830 mm, making it accessible for a wide range of riders. **

Pros

  • Lightweight and agile: The 115 kg design makes for nimble handling and easy maneuverability in tight spaces.
  • Race-inspired performance: With a powerful two-stroke engine, riders experience thrilling acceleration and responsive power delivery.
  • High-quality suspension and brakes: The advanced suspension setup and effective braking system enhance both comfort and safety during aggressive riding.

Cons

  • Limited fuel capacity: With only 10 liters (2.64 gallons), longer rides may require more frequent refueling.
  • Kick starter only: Some may find the absence of an electric starter inconvenient, especially in challenging conditions.
  • Two-stroke maintenance: The engine requires more frequent maintenance compared to four-stroke counterparts, which can be a consideration for some riders.
