If there was ever a bike that looked like it wanted to pick a fight with a supercar and win, it’s the 2026 KTM 1390 Super Duke RR. While the marketing team in Mattighofen calls it their undisputed flagship, most riders are just going to call it the Beast RR.
Built by the mad scientists at KTM in Austria, this isn’t just another pretty face in the showroom. It’s the most extreme version of their Hypernaked philosophy, designed for people who think “too much power” is just a starting point. Here is why the new KTM 1390 Super Duke RR is currently the king of the Naked performance hierarchy.
Shedding Weight to Gain Power
To understand the performance specs of this machine, you have to look at the diet it went on. The engineers managed to strip away 11 kilograms compared to the standard KTM 1390 Super Duke R. That might not sound like much on paper, but in the world of Hypernaked motorcycles, it transforms the bike’s dynamics.
With a stiffer chassis and a massive reduction in mass, the Beast RR is sharper and more agile whether it’s carving through a B-road or hunting for apexes on a racetrack. It’s essentially a high-performance street bike with the soul of a racer.
MotoGP Tech for the Road
The KTM R&D team didn’t hold back on the material choices. They loaded the bike with carbon-fibre components to save weight and give it that aggressive, race-inspired look. But the real magic is in the hardware:
- Suspension: It features WP PRO COMPONENTS derived straight from MotoGP, offering race-level adjustability.
- Wheels & Tyres: It rolls on ultra-lightweight forged wheels wrapped in Michelin Power GP Hypersport tyres.
- Brakes: Serious stopping power is provided by Brembo HyPure Sport front brake calipers.
Firepower and the LC8 V-Twin
At the heart of the 2026 KTM 1390 Super Duke RR sits the latest generation 1350 cc LC8 V-twin engine. This powerhouse pumps out a massive 193 PS and 145 Nm of torque.
KTM has its CAMSHIFT technology, which makes the fuel combustion way more efficient across the entire rev range. And just so everyone within a mile radius knows you’ve arrived, it comes stock with a titanium Akrapovič Slip-On exhaust. It’s got the bark to match the bite.
The Smartest Beast on the Block
The hardware is impressive, but the 2026 KTM 1390 Super Duke RR electronics package is what really sets it apart. It’s the most complete tech suite ever put on a street KTM, with the full TECH PACK features unlocked as standard.
Key Tech Highlights:
- 8.8” Touchscreen TFT: A massive, crisp display to manage all your settings.
- Track Mode: Includes an all-new laptimer and telemetry stats for the data nerds.
- Beast Mode: A brand-new function designed to extract maximum ferocity from the LC8 engine.
- Aero Upgrades: Subtle winglets around the tank increase downforce, keeping that front wheel on the ground when you twist the throttle.
Only 350 Units Available
This isn’t just a special edition with a fancy sticker kit; it’s a no-compromise Hypernaked machine built to bully superbikes. With a new headlight design and a unique colour scheme, it’s going to stand out in any paddock.
However, if you want one, you’ll need to be quick. The 2026 KTM 1390 Super Duke RR is a strictly limited-edition motorcycle, with only 350 units being produced globally. It’s expected to land at KTM dealers in late April or May.
