2023 KTM 125 SX

All it takes is one hard, fast rip into a loamy berm to know that the 2023 KTM 125 SX is a serious contender in the 125 cc race. Not only has the 'Ring-ting-ting' been given a fuel-injected revival, but the entire motorcycle also benefits from class-leading developments at every end. Boasting accolades such as being the leader in 2-stroke motocross innovation in the modern era, the 2023 KTM 125 SX simply slays the rest of the 125 cc class. All you need do is press the starter, blip the throttle and let rip.

Features may include:

  • Easy suspension adjustment

Get dialed in! The 2023 KTM SX range boasts totally tool-free suspension setup at both ends. Thanks to an all-new shock absorber design featuring hand-adjustable dual compression control, it allows riders to adjust high- and low-speed settings in a matter of seconds. On the front end, the forks are also easily adjusted thanks to a single air pressure preload valve, as well as through easy access click adjusters for compression and rebound. We'll even throw the air pump in as standard.

  • Performance

Designed to churn out more torque than any 125 cc 2-stroke engine to ever come before it, the 2023 KTM 125 SX is set to continue its dominance in its class with unrelenting forward momentum. With an overall engine weight of only 39.3 lb and impressive horsepower figures, this lightweight powerplant retains its typical high-revving character, while laying down the grunt where it matters most.

  • Ergonomics

The 2023 KTM SX and SX-F range feature an entirely new and improved rider triangle, providing improved knee contact - especially when standing on the pegs - with improved gripping surfaces all around. New plastics work to expel mud buildup in wet, muddy conditions, with a new, flatter seat profile and high grip seat cover providing exceptional rider movement and control. The polyamide reinforced aluminum subframe further enhances rider feel and feedback.

  • Traction

Ready to rip your arms out of the sockets? Together with the benefits of mass centralization and an overall lighter feel, the anti-squat behavior of the chassis is significantly improved by changing the backbone of the steel frame concept. In layman's terms, the 2023 KTM 125 SX gets its power down perfectly when tearing out of corners.

  • Energy Absorption

Besides the expertly crafted, hydro-formed, laser-cut, and robot-welded frame being engineered to provide exceptional rider feedback and straight-line stability, it consists of specifically calculated parameters of longitudinal and torsional flex. This means the frame acts as a "shock absorber" of sorts, making for a less harsh ride, resulting in less rider fatigue over many hard laps.
