2025 KTM SX and SX-F Motocross Range Unveiled: Improved Rider Control and Fan Favorite Returns
KTM has pulled the wraps off its highly anticipated 2025 SX and SX-F motocross range and the return of 2025 150 SX which is promising for riders to take a significant step up in terms of control, composure, and overall riding experience. This latest version features a series of upgrades inspired by KTM's Factory Racing efforts, maintaining its position as the most competition-ready lineup yet.
The most noticeable changes come in the frame department. The new frame features strategic cutouts and adjustments to the tube wall thickness around the front section, engine mounts, and rear shock mounting points. This translates to optimized flex characteristics, shedding roughly 300 grams without compromising stability. Improved cornering behavior is another benefit of the revised frame. An updated swingarm with a machined chain glider and a revamped rear brake pedal round out the chassis upgrades, enhancing durability for aggressive riding.
Equipping the 2025 SX and SX-F models are the all-new Dunlop GEOMAX MX34 motocross tires. Designed to deliver exceptional stability and control, these tires boast a new carcass compound for improved damping and shock absorption, translating to a 30% performance boost over previous iterations. Additionally, the Progressive Cornering Block Technology enhances traction, grip, and mud clearance for a confident ride in any condition.
The WP XACT rear shock receives an update in the form of a revised linkage with fresh seals and smaller diameter linkage bolts. This setup, derived directly from the KTM Factory Racing Team, delivers weight savings and optimized stiffness. Complementing the rear suspension tweaks, the WP XACT AER fork sports reworked settings to account for the frame's increased flex and reduced weight.
The 2025 KTM SX and SX-F range showcases a refreshed look with all-new tank shrouds featuring bi-composite plastics on both the upper and lower sections. This not only injects a modern aesthetic but also improves cooling and protects the frame from wear. Additionally, an updated fuel tank roll safeguards the frame and enhances the tank's overall fit.
For riders seeking additional adjustability options, the 2025 KTM SX-F lineup offers the Connectivity Unit Offroad (CUO) as a KTM PowerPart. This system, controllable via the KTMconnect app, unlocks a variety of functionalities. The CUO itself mounts on the right upper fork tube, while a GPS sensor sits on the front fender.
After a much-anticipated break, the beloved KTM 150 SX rejoins the 2-stroke lineup for 2025. Building upon the foundation of the KTM 125 SX, the 150 SX features a significant overhaul of components. Specifically designed and modified to deliver superior performance, it promises riders an enhanced powerband and a richer riding experience.
The 2025 KTM SX and SX-F motocross range represents a commitment to providing riders of all skill levels with the perfect machine to dominate the track. With a focus on improved control, refined suspension, and a host of additional upgrades, KTM has ensured its latest offering remains at the forefront of motocross competition.
