2025 KTM 350 SX-F

Designed to provide maximum airflow, the air filter box is designed with precisely positioned inlet ducts aimed at preventing air deformation and maintaining filter protection. The Twin Air filter and air filter support design feature a simple fail-proof mounting system for safe and accurate filter installation, ensuring the air filter is easily accessed, without tools, by removing the left side panel, for easy track-side maintenance. A vented air filter box cover is also included for all SX and SX-F models in the by-pack.

The 2025 KTM SX and SX-F range is engineered and designed to provide riders with easy-to-access service parts, as well as suspension adjustability. This allows faster track-side and off-season maintenance, as well as making motocross more accessible for novice riders without pit crews.

Launch control, ENGAGED! Designed for the holeshot, the 2025 KTM SX-F range comes standard with launch control and Quickshifter function, allowing for fast upshifts without using the clutch. Launch control is easily engaged by pressing the traction control and Quickshifter buttons simultaneously and works by limiting the amount of power to the rear wheel, improving traction, and preventing loss of control under hard acceleration. Meanwhile, the Quickshifter function means you can bang through from 2nd to 5th gear with your focus solely on the first corner.

The map select switch on the 2025 KTM SX models features a simpler design, allowing for easier functionality in switching between 2 engine maps. Map 1 provides a more linear power curve. while map 2 punches all-out with aggressive throttle and explosive power. Luckily, traction control is easy toggled to an on or off position from the same switch, ensuring maximum traction and a distinct advantage in wet or muddy conditions.

Upgraded tank shrouds using bi-compound plastics channel air towards the radiators more efficiently, while a new fuel tank roll, makes for a tighter, more secure fitment, reducing the chance of frame scrubbing and dramatically improving durability. All this works alongside the specially-developed rider triangle, to provide unmatched knee contact and gripping surfaces - especially when standing on the pegs.

The 2025 KTM 350 SX-F engine is tilted 2° backward, this means greatly improved mass centralization and reduced overall weight, benefiting handling and anti-squat behavior. A silencer offers an improved response in combination with the mapping switch and provides a slightly quieter exhaust note.

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.

Keeping things in check at the rear, the WP XACT rear shock has also undergone some changes for 2025 using settings directly from the KTM Factory Racing Teams The improved frame and shock geometry mean more ground clearance at the linkage, making it less susceptible to bottoming out. While we're on the topic, smaller diameter linkage bolts save weight, while new linkage seals refine rear shock response and advanced damping characteristics.

An upgraded rear brake pedal finds its way onto the 2025 KTM Motocross range, adding additional stiffness, bending resistance and braking feel to the overall package. At the other end, a forged steering head connection and CNC-milled triple clamps, make for the perfect alignment of the fork tubes. This precise geometry of the fork clamps ensures highly responsive and smooth fork action – not to mention unwavering stability when charging across ruts and onto the podium.

Ready to rip your arms out of the sockets? Together with the benefits of mass centralization and overall reduced weight, the anti-squat behavior of the chassis is significantly improved by changing the backbone of the steel frame concept. In layman's terms, the 2025 KTM 350 SX-F gets its power down perfectly when tearing out of corners.

Getting power hooked into the dirt is a tough job. However, hours of research and testing have led the 2025 KTM Motocross range to the Dunlop GEOMAX MX34. Providing unmatched stability and control at the highest level, these rubber hoops feature a new carcass and rubber compound that improves damping and absorption, maintaining performance up to 30% longer. New Progressive Cornering Block Technology also improves grip in the berms, while a new rear pattern with 11% taller and 44% wider center block for increased traction and control everywhere else. Lastly, this unique block arrangement works to dispel mud buildup, ensuring traction in even the muddiest of track conditions.

No one enjoys a bad hook-up. Good thing, then that the shock absorber geometry on the 2025 KTM 350 SX-F improves ground clearance of the linkage, with the topology-optimized die-cast footpegs being less susceptible to hooking on deep ruts, and take-offs when scrubbing.

A new chain guide and chain guard result in improved durability and minimize the chances of hooking on external objects - especially in extremely muddy conditions while reducing dirt build-up around the swingarm and rear sprocket.

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.
