With every component, material choice and engineering decision bristling with purpose, the 2026 KTM 1390 SUPER DUKE RR has been developed as the undisputed flagship of the KTM street range – you can simply refer to it as the BEAST RR.
Built in the heart of Austria by the engineers at KTM, the new 2026 KTM 1390 SUPER DUKE RR represents the most extreme evolution of KTM’s Hypernaked philosophy. Designed for riders who demand the very highest levels of performance, its existence can be summed up in one key statement: Pure Performance.
Compared to the BEAST it’s based upon – the KTM 1390 SUPER DUKE R – it sheds 11 kilograms, transforming overall dynamics both on the road and at the racetrack. The reduction in mass enhances agility and responsiveness, while a stiffer, more focused chassis delivers greater stability when hunting on the ragged edge.

To achieve this level of ferocity and focus, KTM’s R&D department turned to the very best materials and components available. Extensive carbon-fibre components contribute to dramatic weight savings while reinforcing the bike’s race-inspired design language. Suspension duties are handled by MotoGP-derived WP PRO COMPONENTS, providing race-level performance and extensive adjustability, while forged wheels and Michelin Power GP Hypersport tyres offer a whole new level of riding.
Firepower comes courtesy of KTM’s latest generation 1350 cc LC8 V-twin delivering 193 PS and 145 Nm of torque, complete with new CAMSHIFT technology for improved fuel combustion throughout the rev range, with a titanium Akrapovič Slip-On exhaust providing the necessary bark to this BEAST’s bite.
However, it’s in the effectiveness of getting that power to the ground that makes all the difference to its potency. WP PRO COMPONENTS suspension features MotoGP-derived technology to bring expert-level adjustability and stability, with ultra-lightweight wheels and track-ready Michelin rubber bringing agility and grip, and Brembo HyPure Sport front brake calipers providing the stopping power.
The enhancements don’t stop with the hardware either, with a feast of class-leading technology adding an additional layer to the KTM 1390 SUPER DUKE RR package. In fact, it stakes a claim to having the most complete electronics package ever fitted to a street-going KTM with all TECH PACK features unlocked as standard.
The KTM 1390 SUPER DUKE RR debuts an all-new 8.8-inch touchscreen TFT dashboard, with new lap timer and telemetry stats within TRACK MODE, as well as an all-new BEAST MODE function. These work together with the usual spread of Rider Aids, Ride Modes and ABS functions.
Lastly, the KTM 1390 SUPER DUKE RR sets the tone with subtle but key visual enhancements. Adding winglets around the tank helps increase downforce to reduce front-wheel lift and a new headlight design and colour scheme set it apart from anything else in the car park or track paddock.
Make no mistake, this is no mere special edition. This is a no-compromise Hypernaked machine built to torment superbikes in their own backyard. The 2026 KTM 1390 SUPER DUKE RR is lighter, sharper and more focused than ever before.
It is a motorcycle engineered to sit at the very top of the Naked performance hierarchy, built for riders who demand performance above posing and a BEAST ready to wear the RR badge.
The 2026 KTM 1390 SUPER DUKE RR will be available for £24,999 in authorised KTM dealers from late April 2026, with the UK receiving just 40 of 350 units available worldwide.
