GT vs. Super Duke R: Same Engine, Different Mission – 190 hp for Long-Distance Riding

The KTM 1390 Super Duke GT shares its engine with the 1390 Super Duke R and R EVO: the same 1,350 cc LC8 V-twin producing 190 hp and 145 Nm. The difference is the concept. The GT is a sport-tourer, with bodywork, a two-position height-adjustable windshield, TPMS and cornering lights as standard, front radar with adaptive cruise control and Group Ride mode, a Comfort setting specifically optimized in the semi-active WP suspension, and Michelin Power 6 tires instead of the more aggressive rubber used on the Super Duke R. What it gives up are winglets, a top speed beyond 250 km/h, and the R’s more aggressive ergonomics. What it gains is a 19.5-liter tank, larger than the 17.5-liter tank on the Super Duke R EVO.

The previous 1290 Super Duke GT made 175 hp, weighed 234 kg fully fueled, and most recently cost EUR 22,499. The 1390 is six kilograms lighter, better equipped, and 15 hp stronger. This is not a facelift but a substantially different motorcycle on the same basic platform.

Engine: 190 hp, 145 Nm, Cam Shift, Shorter Gearing – No Overdrive in Fifth and Sixth

The 1,350 cc LC8 V-twin uses a 75-degree cylinder angle, 110 mm bore, and 71 mm stroke, and produces 190 hp at 10,000 rpm and 145 Nm at 8,000 rpm. It is the most powerful series-production road-legal V-twin on the market. Two-stage Cam Shift intake-cam control improves power delivery across the rev range. KTM has geared the GT shorter than the previous 1290: fifth and sixth are no longer overdrive-style ratios but play a meaningful role in everyday riding. That improves real-world usability on roads where riders are not simply cruising permanently in top gear. A hydraulic PASC slipper clutch and Euro 5+ compliance are standard.

Two details matter to potential buyers. Quickshifter+ is not standard, a noticeable omission at this price. Heated grips also cost extra, unusual for a sport-tourer in this class. The AMT automatic transmission from the 1390 Super Adventure S EVO is not currently available on the GT.

WP APEX SAT Gen 3: Semi-Active Suspension With an Improved Comfort Mode

The third-generation WP APEX SAT suspension is the same basic system that debuted on the 1390 Super Duke R EVO, but with a GT-specific calibration. Comfort mode has been significantly improved for long-distance use. The WP SAT system continuously and automatically adapts compression and rebound damping to road conditions and rider inputs. The DCC compression valve continuously monitors suspension movement and acceleration, while the rear shock uses a hydraulic preload adjuster. The Open Cartridge fork is 750 grams lighter than the unit on the 1290 Super Duke R EVO while also being more efficient and responsive.

Travel is 125 mm front and 140 mm rear. Seat height is 834 mm, ground clearance 149 mm, wheelbase 1,491 mm, and steering-head angle 65.3 degrees. An aluminum single-sided swingarm is used. The suspension is not manually adjustable in the traditional sense; electronics do the work. Riders who enjoy turning clickers may need to adapt. Riders who want comfort and consistency over long distances will find the concept highly effective.

Brakes and Radar Electronics: Brembo Stylema, Supermoto+ ABS, Adaptive Cruise Control, Group Ride Mode

Up front, Brembo Stylema radial four-piston Monobloc calipers work on 320 mm discs, controlled by a Brembo MCS brake lever with multi-click adjustment. At the rear, a two-piston Brembo caliper works on a 240 mm disc. Lean-sensitive ABS offers Sport, Supermoto, and Supermoto+ modes. Supermoto+ permits controlled rear-wheel brake drifts – an unexpected feature on a sport-tourer, but one that preserves the Super Duke DNA.

The key electronics difference from the Super Duke R is radar technology. Front radar supports adaptive cruise control, Brake Assist, and a Group Ride mode that optimizes distance control in a convoy. TPMS and cornering lights are standard. Demo Mode is included. The 8.8-inch TFT touchscreen offers offline navigation, split-screen layouts, smartphone connectivity, and USB-C. Rain, Street, Sport, and Custom riding modes are standard.

Ergonomics and Long-Distance Use: 834 mm Seat Height, Two-Position Windshield, 19.5-Liter Tank

The 834 mm seat height is almost identical to the 1390 Super Duke R EVO. The GT is not lower for touring; instead, it is more comfortable through its riding position and wind protection. The windshield adjusts between two height positions and provides substantially better wind protection than the naked Super Duke R. Fully fueled weight is 228 kg with 19.5 liters of fuel, six kilograms less than the previous 1290 Super Duke GT, although that bike carried a larger 23-liter tank. At around 5.9 L/100 km, realistic range is roughly 300 to 320 km, requiring more disciplined fuel stops on long tours than the predecessor.

Michelin Power 6 tires are standard. They are road-oriented sport-touring rubber with a broad operating-temperature window, well suited to travel use. Sizes are 120/70-17 front and 200/55-17 rear. Top speed is electronically limited to 250 km/h, compared with 270 km/h for the Super Duke R. On a touring motorcycle, that distinction is largely academic.

Handling: 190 hp in the Touring Class – No Longer a Compromise Between Sport Bike and Tourer

No other sport-tourer in this segment combines a 190 hp V-twin with semi-active suspension, radar cruise control, and Group Ride mode. The BMW S 1000 XR makes 170 hp from an inline-four and offers semi-active DDC suspension as an extra. The Ducati Multistrada V4 S makes 170 hp from a V4 and comes with semi-active suspension at a higher price. The Honda NT1100 starts much lower, makes 102 hp, and has no semi-active suspension. The GT sits between BMW and Ducati on price while offering the strongest engine of the group.

Its compromises are equally clear. Quickshifter+ costs extra. Heated grips cost extra. A 19.5-liter tank instead of 23 liters means less range. And riders who genuinely want to use 190 hp on a racetrack should buy the Super Duke R EVO. The GT is calibrated for comfort and long distances, even if it remains sportier than almost every other tourer.

Cost and MY2026 Status: No Official German List Price – Estimated From Around EUR 24,000

Concrete German dealer pricing was not available at the editorial deadline. For model year 2026, the motorcycle continues technically unchanged. A prototype with revised bodywork and a redesigned luggage system was spotted testing in the Alps in December 2025, but no official presentation date is known. KTM offers up to four years of Premium Manufacturer Warranty from MY2025, provided scheduled servicing is performed by an authorized KTM dealer.

Verdict

A 190 hp V-twin, semi-active WP suspension, Brembo Stylema brakes, radar cruise control, Group Ride mode, offline navigation, Michelin Power 6 tires, 228 kg fully fueled, and an 834 mm seat. The KTM 1390 Super Duke GT is the fastest sport-tourer at its expected price level. It asks for compromise on Quickshifter+ and heated grips, both extra-cost options, and on fuel capacity at 19.5 liters. But the concept is crystal clear: the Beast tamed for long-distance work – tamed, but certainly not neutered.
