2024 KTM 125 SX

FULL- SCREAM AHEAD

There are very few sounds that can't be beaten: the crack of a soda can on a blistering hot day, the ping of the perfectly executed golf shot, and the scream of a 125 cc 2-stroke full throttle. The KTM 125 SX takes its leads directly from the KTM Factory Racing team for pure performance, pure results. Like the sound it makes, you won't forget it.

Features may include:

BEFORE THE GATE

• Easy Suspension Adjustment

Get dialed in! The 2024 KTM SX range boasts totally tool-free suspension setup at both ends. Thanks to the 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.

START STRONG

• EFI + Power Valve

With EFI comes great rideability. Along with the electronic fuel injection, a electronic Power Valve has also been fitted to the KTM 125 SX, allowing for more usable power throughout the rev range. Smoother power means better traction. Better traction means holeshot heaven!

CALM UNDER FIRE

• Absolute Control

No matter how gnarly the track is, you'll find complete confidence thanks to the frame design that has not only been engineered for longitudinal rigidity but also repositions rotating mass closer to the center of gravity. The shock mounting also provides improved anti-squat behavior for better traction out of corners, while the footpeg mounting position has moved inwards for less risk of hooking up in deep ruts or when scrubbing jumps.

HIT THE BIG STUFF

• Traction

Ready to rip your arms out of the sockets? Together with the benefits of mass centralization and the anti-squat behavior of the chassis, the 2024 KTM 125 SX gets its power down perfectly when tearing out of corners.
