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.
Pre-mix gets a remix across the 2-stroke KTM SX range, with electronic fuel injection setting the standard. Now there's no more fiddly jetting setup pre-race, And thanks to the Keihin EFI and reed valve case design, you can be guaranteed of laying down optimal power at any altitude, all of the time.
Picture this; You're 7 laps into an absolute ripper of a race. You miss your line and end up stalling in a deep rut. But you don't sweat it. All you do is press the starter button and you blast off again to take the final flag. This is the reality on the 2024 KTM 125 SX. Thanks to a 12,8V 2 Ah lithium ion battery is placed under the rider's seat, a high-quality stator & pickup and super robust design, the only thing you'll be kicking - is ass.
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!
The KTM 125 SX has always represented the very best of unsurpassed power and lightweight construction. The simplicity and low maintenance cost of the 2-stroke motor have made it a favorite amongst motocross riders for generations. For 2024, the KTM 125 SX enters with an overall engine weight of only 39.3 lb (17.86 kg), setting the 125 SX engine sets the benchmark in the highly competitive 250 cc class.
The 2024 KTM 125 SX features a map select switch allowing the racer to switch between 2 engine maps. Map 1 provides the ultimate power delivery to dominate hard-pack surfaces, while Map 2 gives you the edge in soft, sandy conditions.
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.
The rider triangle provides ample knee contact - especially when standing on the pegs - to ensure enough gripping surfaces all around. The plastics work to expel mud buildup in wet, muddy conditions, with a flat seat profile and high grip seat cover providing exceptional rider movement and control. The polyamide reinforced aluminum subframe further enhances rider feel and feedback.
With a major emphasis placed on mass centralization, the 2024 KTM 125 SX engine is designed to centralize rotating mass for optimal operation with the chassis. This results in a lighter, more agile handling feel that simply runs rings around the competition.
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.
48mm air type WP XACT front fork with a split damping function provides all the confidence you need to attack the track. Hydrostops in the fork legs improves bottoming-out resistance and account for less rebound when attacking big jumps, bumps, and thumps. Redesigned fork protection rings also increase protection against dirt, making them as reliable as they are awesome.
The KTM 125 SX is rock-solid at any speed thanks to the position of the forged steering head connection and CNC milled triple clamps. Made from high-grade aluminum, these feature optimally tuned steering stem stiffness, perfect alignment of the fork tubes, and precise geometry of the fork clamps to ensure highly responsive and smooth fork action - not to mention unwavering stability when charging across ruts and onto the podium.
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.
The frame and shock absorber geometry improve ground clearance of the linkage and work with topology optimized die-cast footpegs that are less susceptible to hooking on deep ruts, and take-offs when scrubbing.
A WP XACT shock absorber provides unmatched consistency lap after lap, thanks to low-friction SKF linkage seals and advanced damping characteristics for unsurpassed traction and energy absorption.
