We bring you a technical analysis of the new KTM 1390 Super Adventure S that breaks into 2025 not as an evolution, but as a redefinition of what an asphalt maxi-traile can become.
The Austrian firm has applied a total engineering approach, where each component has optimized to raise the performance, technology and pilot experience to a new paradigm. Next, we technically break down this new asphalt sovereign.

Technical analysis by sections
1. Evolved LC8 motor: intelligent power
The soul of 1390 is its renewed V-Twin LC8 engine. The increase in displacement to 1,350 cc, achieved by an increase in the diameter of the cylinders to 110 mm, is only the beginning. True innovation is the introduction of "Camshift" technology in the intake camshaft. This variable distribution system allows two different valve elevation profiles: one optimized to deliver a overwhelming torque and soft driving at low and half revolutions, and another that maximizes the power and response in the upper area of the venue account. The result is an engine that meets the strict Euro5+ regulations without sacrificing an apex of its character, offering a duality never seen between docility and fury.
2. Cycle and suspensions: Total control
The characteristic steel multitubular chassis has been reviewed to increase its torsional rigidity, which translates into greater precision and curve stability. However, the true crown jewel is the third generation of WP SAT semi-active suspensions (Semi-Active Technology) . Through a suspension control unit (SCU) that processes 6 -axle IMU data and multiple sensors, the suspensions are adjusted in real time in milliseconds. The system manages damping, preload and even has an "anti-dive" function that prevents excessive sinking of the front train into strong braking, maintaining the geometry of the motorcycle always at its optimal point.
3. Vanguard Electronics: The brain of the beast
The 1390 Super Adventure S is a demonstration of electronic power. Package Included:
- Driving modes: Rain, Street, Sport and Offroad as standard, which act on the accelerator response, traction control (MTC) and ABS. Rally mode (optional) allows an adjustment of the MTC sliding in 9 levels.
- Adaptive Cruise Control (ACC): Use a latest generation radar sensor to maintain a safe distance with the preceding vehicle, even in dense traffic thanks to the Stop & Go .
- 8 -inch TFT screen: With a redesigned interface, it is the command center from which all telemetry, navigation and connectivity are managed through the KTMConnect app.
4. Ergonomics and functional design
Each element has been designed to improve the experience on long trips. The new body design and the adjustable dome have been optimized in the wind tunnel to improve aerodynamic protection and divert the heat of the engine away from the pilot. The seat, with a new invoice, is adjustable in two heights (847 and 867 mm) without tools, allowing a perfect adaptation to pilots of different sizes and improving comfort in long runs.
Conclusion: The definitive maxi-trail for asphalt
The KTM 1390 Super Adventure S 2025 is not just a powerful motorcycle; It is an advanced engineering machine designed with a clear purpose: master the road. The combination of a brutally effective engine and at the same time docile, a reactive chassis and an electronics that touches telepathy, position it as the new reference for those who seek maximum benefits and the most advanced technology in a versatile and comfortable trail format. KTM has put all the meat on the grill, creating not only the successor of the 1290, but to the probable queen of the category for the coming years.
