From a press release issued by KTM:

In receiving its boldest transformation yet, the 2025 KTM 1390 SUPER DUKE GT takes another significant leap forward and accelerates further ahead of the chasing pack. THE LONG DISTANCE BEAST just got even more radical, fulfilling its design brief to meet incredible dynamism, and taking the Sports Tourer category to exceptional new heights.

Already the most extreme bike in its segment – it has adrenaline rush at its core, boasting class-leading technology, superior handling, and an engine package that is even more powerful and torquey than ever before. It’s a refined package that delivers more muscle and aggression than its predecessors.

Now boasting a displacement of 1350 cc and sharing the same latest LC8 V-twin engine of the 2024 KTM 1390 SUPER DUKE R EVO, the upgrades further optimize performance and takes the new generation to new heights. A centrally positioned ram air intake, a redesigned air box, and a wider radiator are just a few of the enhancements that boost both power and efficiency, taking its capabilities to the next level.

Riders will be able to take full advantage of revised gearing that makes 5th and 6th gears far more effective, resulting in better use of the rpm range – they’re no longer considered to be overdrive gears at moderate speeds, which makes for a more READY TO RACE motorcycle. The goal was clear: to create an exceptionally fast road bike with serious track ambitions, delivering peak performance in every scenario.

The Kiska design team has gone to work on every single angle, developing superior, more compact ergonomics that enable riders to spend long hours in the saddle, while also maintaining the opportunity to unleash its improved performance on track. An all-new signature LED headlight and simplified brake light with integrated turn signals add to the bike’s bold styling, complete with a lower profile that emphasizes its most up to date chassis. 

In terms of handling, the 2025 KTM 1390 SUPER DUKE GT receives the latest-generation chassis from THE BEAST, the 2024 KTM 1390 SUPER DUKE R EVO. This chassis provides increased torsional stiffness and a lower center of gravity, offering optimal front tire feedback for superior control. Stability, combined with agile, sporty handling, has been further refined through the addition of the latest generation WP APEX Semi Active Technology (SAT) suspension components at both the front and rear. Also improved, is the heavily revised Comfort Mode for those longer days in the saddle – this was a major focus in the development phase and one that riders will feel the biggest difference from the previous generation model. This setup improves sensitivity, responsiveness, and offers greater customization options, delivering a more dynamic and adaptable riding experience.

With the boost in performance, you’ll need equally strong stopping power, which is achieved by the proven Brembo systems. Up front, it features a set of four-piston Stylema monoblock calipers gripping 320 mm floating discs, while the rear is equipped with a Brembo twin-piston floating caliper and a 240 mm disc for precise, controlled braking. A new MCS (multi-click-system) front brake lever enables increased adjustability, while Cornering ABS, Supermoto ABS, as well as the new Supermoto+ and Sport ABS modes provide riders with multiple options to control THE LONG DISTANCE BEAST.

Fitted with lightweight Michelin Power 6 tires featuring dual compound technology, straight line/cornering grip has been enhanced. Additionally, a new Tire Pressure Monitor System (TPMS) with improved functionality allows riders to set a custom pressure for track riding.

A state-of-the-art electronics package has been developed and incorporated, offering class leading rider aids and a new Ride Mode concept. Its revolutionary 8.8-inch TFT (H88) touchscreen dashboard cannot be ignored, benefiting from a simplified menu structure, the CCU3.0 also ensures seamless reconnection with your smartphone on every ignition cycle. Functionality is at a premium including Offline Map Navigation, with relevant safety features integrated, and all able to be operated at the press of a button on the all-new handlebar switch cubes.

That high-tech experience extends to the Ride Modes, which are completely reworked and made up of Rain, Street, Sport as well as an all-new Custom mode as standard, in addition to optional 2 Custom configurations and an optional Track Mode that adds to its personalization capabilities. Keeping the tech experience at an all-time high is the addition of a Front Radar which adds a host of features such as Adaptive Cruise Control, Brake Assist, Distance Assist and Group Riding. Demo Mode is also available for the first 1,500 km that permits customers to sample all the available tech in order to make an informed decision which tech pack best suits their needs.

With a major step forward for improved street riding character that doesn’t compromise its capabilities on the track, the opportunities are endless aboard the 2025 KTM 1390 SUPER DUKE GT. It’s more of a BEAST than ever before and is prepared to go the distance – are you?

A full selection of KTM PowerParts and KTM PowerWear have also been developed for the 2025 KTM 1390 SUPER DUKE GT riders, providing first-class personalization options, purposely crafted to elevate performance and protection, no matter how far or fast your journey will be.
