2025 KTM 250 SX F Easy Suspension Adjustment

As always, the suspension boasts an easy tool-free setup at both ends, ensuring you chase down the podium in total control. On the rear, a hand-adjustable dual compression control allows riders to adjust high- and low-speed settings in a matter of seconds. The forks on the front end are also easily adjusted thanks to hand-adjustable clickers on the bottom of the fork shoe and top cap.

2025 KTM 250 SX F Airbox

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 secure 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. 

2025 KTM 250 SX F Serviceability

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.

2025 KTM 250 SX F More Usable Power

Weighing in at a lightweight 57.5 lb (26.11 kg), this mid-weight powerhouse churns out a remarkable payload, making it the undisputed performance leader in the 250 cc 4-stroke class. The engine in the 2025 KTM 250 SX-F has also been carefully designed and tuned to best suit the performance and handling characteristics of the overall package, bumping up power in the mid-range and the top-end. 

2025 KTM 250 SX F Launch Control & Quickshifter

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.

2025 KTM 250 SX F Selectable Maps + TC

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.

calm under fire

2025 KTM 250 SX F Absolute Control

Get ready for a full-on berm assault. The 2025 KTM SX and SX-F machines have received major frame updates directly from Factory Racing efforts. For starters, the frame area around the rear shock mount has been updated and made more streamlined, with new engine mounts and cut-outs for improved chassis flex. The front area of the frame is also updated. with a different wall thickness than the previous model year, with renewed engine mounts. This adds up to a 300g weight saving and improved flex for better cornering.

2025 KTM 250 SX F Ergonomics

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.

2025 KTM 250 SX F Performance

The 2025 KTM 250 SX-F engine is positioned for optimal mass centralization and an overall lightweight feel, benefiting handling and anti-squat behavior. The silencer offers incredible response in combination with the mapping switch and provides a slightly quieter exhaust note. 

hit the big stuff

2025 KTM 250 SX F Updated Suspension Settings

For 2025, the KTM SX and SX-F range has given the WP XACT AER fork and WP XACT rear shock an update. This means you'll be lining up at the starting gate with re-tuned settings, reduced weight, improved weight distribution, and an increase in overall response.

2025 KTM 250 SX F WP XACT Fork 

Let's get the technical parts out of the way first; the 48 mm WP XACT AER forks fitted to the 2025 KTM SX and SX-F line-up features a capsulated air spring and pressurized oil chamber for progressive and consistent damping, while oil and air bypasses reduce pressure peaks. In combination with the mid-valve damping system, all this provides exceptional feedback and rider comfort. The fork also boasts new settings, which not only compliment the updated frame and rear linkage, but ensures stellar performance at all levels. Speaking of settings, these are easily adjusted via a single air pressure pre-load valve, as well as easy-access click adjusters for compression and rebound. Additionally, the air pump needed to adjust the fork's air pressure is provided as standard in the buy-pack. 

2025 KTM 250 SX F WP XACT Shock

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.

2025 KTM 250 SX FStability

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. 

2025 KTM 250 SX FMass Centralization

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 250 SX-F gets its power down perfectly when tearing out of corners. 

2025 KTM 250 SX FTires

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. 

maintaining momentum

2025 KTM 250 SX F Connectivity Unit Offroad

Available as a PowerPart on the KTM SX-F range, the Connectivity Unit Offroad - or CUO for short - offers a wide range of functionalities and adjustability options via the KTMconnect app. The CUO gives you a new insight into your riding, allows you to alter your engine behavior, and even provides you with optimized suspension settings based on individual preferences and riding conditions. Welcome to the next level moto. 

2025 KTM 250 SX F Ground clearance 

No one enjoys a bad hook-up. Good thing, then that the shock absorber geometry on the 2025 KTM 250 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. 

2025 KTM 250 SX F Consistency

 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.

2025 KTM 250 SX FEnergy 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.
