Overview

Introducing the 2016 KTM 125 SX, a formidable contender in the cross-motocross segment that embodies the spirit of competition and the thrill of off-road riding. This lightweight, agile machine is designed for riders who crave the adrenaline rush of dirt track racing and trail exploration. As a part of KTM's renowned SX lineup, the 125 SX is built for performance, delivering a pure motocross experience that is both exhilarating and accessible, making it perfect for aspiring racers and seasoned riders alike. At the heart of the 125 SX lies a robust 124.80 cc single-cylinder, two-stroke engine that is engineered to deliver an impressive punch. With a bore and stroke of 54.0 x 54.5 mm, this powerplant is optimized for peak performance and responsive acceleration. The fully electronic ignition system, featuring digital timing adjustment, ensures that every twist of the throttle translates into instant power delivery, while the liquid cooling system keeps temperatures in check during intense rides. Coupled with a 6-speed gearbox and a multi-plate Brembo hydraulic clutch, the 125 SX offers riders an engaging and seamless gear-changing experience, enhancing both control and agility on any terrain. The 2016 KTM 125 SX is packed with advanced features that elevate its off-road capabilities. Its chrome-molybdenum steel central-tube frame is lightweight yet robust, ensuring durability and stability during high-speed runs and sharp turns. The WP-USD AER 48 front suspension and WP rear shock absorber provide a plush 300 mm of travel, absorbing bumps and enhancing rider comfort on rugged trails. The braking system is equally impressive, featuring single discs at both ends with floating calipers that offer exceptional stopping power and modulation. With a ground clearance of 375 mm and a seat height of 960 mm, the bike is designed to navigate obstacles with ease while accommodating a variety of rider sizes. **

Pros

  • Lightweight and Agile: At just 87.8 kg (193.6 lbs), the 125 SX offers superior maneuverability, making it ideal for tight tracks and technical terrains.
  • Powerful Two-Stroke Engine: The responsive and punchy engine delivers exhilarating acceleration, perfect for competitive racing.
  • Advanced Suspension System: The WP suspension provides excellent shock absorption, ensuring a smooth ride even over rough landscapes.

Cons

  • Limited Fuel Capacity: With a fuel tank capacity of only 7.00 litres (1.85 gallons), longer rides may require frequent stops for refueling.
