In the world of high performance motorcycles, there are fast bikes, and then there is “The Beast.” KTM has officially pulled the wraps off its most extreme street legal creation to date: the 2026 KTM 1390 Super Duke RR. This isn’t just a minor update it is a limited edition, track focused weapon that sits at the absolute pinnacle of the Austrian brand’s street line-up.
With only 350 units being produced for the entire world, this motorcycle is a rare gem designed for those who believe that enough is never enough. It takes the already terrifying performance of the standard 1390 Super Duke R and pushes it into a territory usually reserved for factory racing machines.
Engine and Performance: V-Twin
At the heart of this machine is the latest evolution of KTM’s legendary LC8 V twin engine. Displacing 1,350cc, this powerhouse is a “torque hungry” monster that produces a staggering 192.6 PS (193hp) and 145 Nm of torque.
What makes this engine truly special for 2026 is the integration of new CAMSHIFT technology. This system optimizes fuel combustion across the entire rev range, ensuring that power delivery is as efficient as it is explosive. KTM describes the performance as so intense that the bike doesn’t just move forward; it feels like it “spins the world below it”. To ensure it breathes as hard as it runs, the bike features a ram air system and a redesigned 10 litre airbox that mimics the oxygen consumption of a cheetah at full pace.
Completing the performance package is a standard-fit titanium Akrapovic slip on exhaust system. Not only does this reduce weight, but it also provides a sharper throttle response and the signature, aggressive growl that enthusiasts expect from a top tier KTM.
The Weight Loss Secret: 11kg Lighter
The “RR” badge is earned through a radical commitment to weight reduction. The 2026 model is a full 11kg lighter than the standard 1390 Super Duke R, bringing it closer to a 1:1 power to weight ratio.
This massive weight saving is achieved through the extensive use of carbon fibre throughout the bodywork. One of the most impressive structural changes is the ultra lightweight, single piece carbon fiber undertray, which supports the unique single seater setup. By removing the pillion seat and foot pegs, KTM has signaled that this is a machine for the solo rider who is focused entirely on the thrill of the ride.
Further weight was trimmed from the unsprang mass. The bike rolls on 7-spoke forged wheels designed in the style of the RC16 MotoGP bike. These wheels are 1.5kg lighter than the stock versions, which drastically improves agility, braking response, and the ease with which the bike changes direction at high speeds. These rims are wrapped in ultra-grippy Michelin Power GP (or Power Cup 2) hyper sport rubber to ensure maximum traction.

Race Grade Hardware and Handling
When it comes to handling, KTM has reached for the “highest shelf”. The 1390 Super Duke RR features a full suite of WP PRO COMPONENTS, derived directly from MotoGP technology.
Up front, you’ll find WP PRO COMPONENTS Closed Cartridge spring forks. This system allows riders to finely tune compression and rebound damping for specific track conditions without the limitations of standard hydraulic strokes. At the rear, a custom made WP PRO COMPONENTS shock provides almost limitless adjustability, offering superior rear end stability and grip for earlier acceleration out of corners.
Stopping this beast is handled by Brembo Hy Pure Sport front calipers, which replace the older Stylemark units. These are paired with 320mm floating discs and a Brembo MCS (multiple click system) hand lever that allows for a more consistent pressure point and reduced lever force. The system also features self-venting cylinders, eliminating the need for frequent hydraulic bleeding even under heavy track use.
Electronics: Introducing “Beast Mode”
The 2026 KTM 1390 Super Duke RR debuts what KTM calls the “best user interface in the segment”. It features a massive 8.8-inch landscape TFT touchscreen. This display is designed for real-world use, with coatings that prevent glare and fingerprints, and a screen that works perfectly even with thick winter gloves.
Riders have access to 8 individual Ride Modes. While the standard Street, Sport, and Rain modes offer varying levels of traction control and power, the Track Mode unlocks a telemetry screen showing lean angles and G-forces.
However, the headline feature is the new Beast Mode. When engaged, the screen strips away all distractions, showing nothing but your speed. It also purposefully disables or dials back electronic interventions to their lowest legal limits, allowing the rider to experience the bike’s “full fury unleashed”. As an added bonus, all “Tech Pack” features come unlocked as standard on this limited edition.

Aggressive Design and Ergonomics
Visually, the RR is a warning to all challengers. It features a predatory LED headlight with a signature welcome animation and daytime running lights that adjust based on ambient light. The bike’s profile is dominated by aero winglets on the fuel tank, which are not just for show they increase downforce at high speeds to keep the front wheel planted.
The ergonomics are 100% hardcore. The 17.5-litre fuel tank is 1.5 litres larger than the previous version, extending the range to roughly 300km. It is angled specifically to support the rider’s knees during heavy braking and deep lean angles. Additionally, the handlebars, shifting controls, and braking controls are fully adjustable, even allowing for a reverse shift pattern for track enthusiasts.
2026 KTM 1390 Super Duke RR Conclusion
