KTM has a reputation for building motorcycles that are, quite frankly, a bit unhinged. But every few years, the engineers in Mattighofen decide that “unhinged” simply isn’t enough. Enter the 2026 KTM 1390 Super Duke RR—a carbon-clad, track-focused evolution of the already manic Super Duke R.
If the standard 1390 is “The Beast,” the RR is the version that has spent its off-season in a high-intensity training camp. It’s leaner, sharper, and restricted to just 350 units globally, making it an instant collector’s item for the orange-blooded faithful.
The Art of Losing Weight: 11kg of Pure Performance
In the world of hyper-nakeds, weight is the enemy of agility. KTM’s primary mission with the RR was a strict diet. Through the obsessive use of lightweight materials, they have managed to shave 11kg (approx. 24 lbs) off the standard model.
This isn’t just about surface-level changes. The weight loss comes from critical areas that transform how the bike handles:
- Carbon Fiber Mastery: Almost every piece of bodywork has been replaced with high-grade carbon fiber, including a unique lightweight subframe.
- Unsprung Weight: The bike features specialized forged wheels. By reducing mass here, the RR can change direction with a telepathic level of quickness.
- Titanium Roar: A standard-fit Akrapovič slip-on exhaust not only reduces bulk but provides the guttural, rhythmic soundtrack that defines the LC8 V-Twin.
KTM 1390 Super Duke RR Anatomy of a 193hp Monster
At the heart of the RR lies the updated 1,350cc LC8 V-Twin engine. While the raw numbers—193hp and 145Nm of torque—are identical to the standard 1390, the way that power is delivered in the RR is vastly different.
With the reduced weight, the bike achieves a near 1:1 power-to-weight ratio. To keep the front wheel from constantly reaching for the sky, KTM has integrated aggressive aerodynamic winglets on the tank spoilers. These aren’t just for show; they provide tangible downforce to keep the bike planted during high-speed corner exits.

Professional-Grade Hardware
You don’t put “RR” on a fairing unless the chassis can back it up. KTM has ditched the standard (already excellent) suspension for WP Apex Pro Components. This is professional racing hardware, offering a range of adjustability that allows riders to tune the bike for specific tracks or tarmac conditions.
Stopping power has also seen an upgrade. The bike now sports Brembo Hypure front calipers. These are lighter and more rigid than the previous Stylema units, offering more “feel” at the lever—crucial when you’re braking at the end of a 280km/h straight.
Tech Intelligence: Welcome to “Beast Mode”
The cockpit has undergone a digital revolution. A massive 8.8-inch TFT touchscreen serves as the command center. It’s crisp, glare-resistant, and introduces a revised user interface.
The headline electronic feature is the new “Beast Mode.” This setting strips away the safety nets, sharpens the throttle to a razor’s edge, and optimizes the electronics for maximum track performance. Furthermore, the RR comes with the KTM Tech Pack fully unlocked as standard, giving owners access to engine brake control, motor slip regulation, and advanced telemetry data to analyze their lap times.
The Final Word: A 350-Unit Legacy
The 2026 KTM 1390 Super Duke RR is likely to be one of the final “pure” internal combustion masterpieces from the brand before hybridization or electrification begins to seep into the lineup.
It is a raw, unapologetic celebration of mechanical engineering. With only 350 units available, it isn’t just a bike—it’s a ticket into an exclusive club of riders who demand the absolute limit of what two wheels can provide.
Expect these to vanish from the digital showroom in minutes.
