KTM does nothing in moderation. Case in point: the 2025 KTM 1390 Super Duke GT.
Flagship sport-tourers often find the happy medium between pulse-raising performance and long-haul comfort. That balance is frequently achieved by sacrificing outright performance. KTM makes no concessions with the latest-generation Super Duke GT.
Harnessing the same LC8 V-twin that debuted in the 1390 Super Duke R EVO, the GT now pumps out 187 horsepower and 107 foot-pounds of torque (claimed). For context, that amounts to a gain of 15 horsepower and three foot-pounds over its predecessor, the 1290 Super Duke GT. KTM attributes the performance boost to a redesigned airbox, a wider radiator, repositioned injectors, and a central ram air intake. We’re pretty sure the mill’s 1,350 cc displacement has something to do with it, too.
The GT also pinches the Super Duke R EVO’s WP APEX semi-active suspension. According to KTM, the electronically adjustable suspenders now offer a highly improved Comfort mode, which caters to pavement-pounding travelers. Still, Team Orange reports that the 1390’s torsional stiffness is three times that of the 1290’s, leading to more precise handling and enhanced stability.
With more power comes more stopping power, as the GT now dons a set of Brembo Stylemas up front and a two-pot Brembo binder out back. Completing the chassis is a set of Michelin Power 6 tires, which prioritize both long-distance longevity and cornering grip, thanks to dual-compound technology.
Technology also separates the Super Duke from many of its grand-touring contenders. Radar-aided features like Adaptive Cruise Control, Brake Assist, Distance Assist, and Group Riding speak to the model’s touring aspirations while Cornering ABS, Supermoto ABS, and the new Supermoto+ mode hint at its hooligan alter ego. All that is in addition to the GT’s four ride modes (Street, Sport, Rain, and Custom) and KTM’s all-new 8.8-inch TFT (H88) touchscreen.
Options like a Track and two additional Custom riding modes are also available. KTM’s Demo Mode allows customers to sample all the model’s available gizmos for the first 1,500 km (932 miles). Should the owner want the optional features thereafter, they will need to purchase them.
Of course, performance, luggage, and crash protection accessories are available via KTM’s PowerParts catalog. Unfortunately, KTM has yet to announce the 1390 Super Duke GT’s MSRP and availability.
Editor's note: Update — on November 18, KTM announced the 1390 Super Duke GT will not be coming to North America for the 2025 model year.
