In 2023, KTM revamped its Motocross lineup, and the 2025 iterations of the KTM SX and SX-F range continue to push the boundaries with new technology aimed at enhancing rider connection, composure, and control.
A notable inclusion in the lineup is the return of the 150SX model, catering to enthusiasts of small-bore two-stroke platforms. The highlight of this update is the introduction of an all-new frame, initially showcased on the Factory Edition models announced a couple of months ago.
The frame undergoes significant changes with visible cutouts and adjustments in tube-wall thickness around critical areas like the front, engine mounts, and rear shock mounting zones.
These alterations aim to enhance chassis flex characteristics, reduce weight by approximately 300 grams, and improve overall stability and cornering behavior. Complementing the frame updates are enhancements to the swingarm and rear brake pedal, contributing to improved durability and performance.
The 2025 KTM SX and SX-F models come equipped with Dunlop GEOMAX MX34 Motocross tires, featuring a new carcass compound for improved damping and absorption, extending performance by up to 30%. Progressive Cornering Block Technology enhances traction, grip, and mud dissipation, ensuring riders can perform at their best in various conditions.
In terms of suspension, both the WP XACT rear shock and WP XACT AER fork receive updates derived directly from KTM Factory Racing Team, focusing on weight savings and stiffness optimization. Ergonomic improvements include new tank shrouds with bi-composite plastics for improved cooling and a refreshed appearance, along with an updated fuel tank roll to enhance frame protection and fitment.
Visually, the 2025 models showcase a new design language reflected in the graphics and bodywork, signaling the technical advancements integrated into the lineup. Full-orange bodywork, red and black in-mold graphics, and a more durable black seat contribute to a clean aesthetic while emphasizing the READY TO RACE ethos.
Furthermore, the 2025 KTM SX-F models feature a new exhaust silencer, delivering crisper performance and torque in the midrange, along with switchable engine maps for added versatility. The reintroduction of the KTM 150 SX caters to riders seeking elevated performance, offering enhanced torque and an enriched riding experience.
The introduction of the Connectivity Unit Offroad (CUO) for the 2025 KTM SX-F line-up brings various functionalities and adjustability options via the KTMconnect app, enhancing the overall riding experience.
