KTM 1390 Super Duke GT is most focused version to date with new engine and semi-active suspension

KTM don’t like to take things easy and despite their Super Duke GT being the firm’s relaxed sports touring option, 2025 sees it gain not only some new tech but also a sportier focus through enhanced performance and a sharper chassis.

Starting at its heart, the GT now boasts the updated 1350cc version of the firm’s LC8 V-twin. Identical in its spec to the motor that powers the 2024 1390 Super Duke R EVO, that should mean it makes a claimed 187.7bhp with 107ft.lb of torque, although KTM are yet to officially confirm the GT’s stats.

To go with this more powerful engine, KTM have given the GT a centrally mounted ram air intake, redesigned airbox and a wider radiator in a fairly substantial facelift – all measures aimed at ensuring it doesn’t lose any performance, which is important as they have also changed its focus.

There has been a conscious decision by KTM to move the GT towards the sporty end of the sports touring spectrum and as well as its more powerful engine, the 2025 GT boasts revised gearing to give it added punch in fifth and sixth at the expense of easy-going overdrive ratios. And the sporty enhancements don’t stop there.

As well as a new chassis taken directly from the 1390 Super Duke R EVO, which is both stiffer and more agile than the previous generation of GT’s chassis, the 2025 bike comes with the latest generation of WP APEX semi-active suspension (SAT).

Similar to the units on the current model, KTM have focused development time on Comfort Mode’s settings in an effort to make the GT more compliant for long days in the saddle, a factor helped by a new compact riding position.

Tech-wise, as well as a forward radar adding adaptive cruise control and more, the GT comes with angle-responsive electronics (including the new Supermoto+ and Sport ABS settings).

A new tyre pressure monitoring system with a track setting, revised rider modes with a new Custom mode (and optional Custom and Track modes) and KTM’s latest 8.8in touchscreen TFT dash with its updated interface and connectivity complete the line up.

The 1390 Super Duke GT will be in dealers in January 2025 with its price confirmed at a later date.
