2026 KTM 1390 Super Duke RR Revealed with LC8 V-twin Engine

The 2026 KTM 1390 Super Duke RR is here, and it is easily the wildest version of KTM’s flagship naked bike yet. Built as a more hardcore, track-focused machine, the new RR sits above the regular Super Duke R and R EVO. KTM will build only 350 units worldwide, so this is going to be a rare sight on the road. Compared to the standard bike, the RR is 11kg lighter, tipping the scales at 189kg. KTM has shaved off the extra weight with carbon-fibre bodywork, a cast aluminium subframe, forged wheels and a lighter lithium-ion battery.

2026 KTM 1390 Super Duke RR: Design & Features

Visually, the new KTM 1390 Super Duke RR looks sharper and more aggressive than the regular model. It gets a redesigned LED headlight, a special RR-only paint scheme and winglets mounted on the fuel tank shrouds. These winglets are there to improve stability at high speeds and help keep the front end planted when you are hard on the throttle.

The forged seven-spoke wheels also reduce unsprung weight, which should make the bike feel quicker to turn and easier to flick from side to side.

KTM has given the Super Duke RR a big electronics package. There is a new 8.8-inch touchscreen TFT display with a revised layout, along with the Tech Pack as standard. Riders also get track telemetry and a new Beast mode, which lets you fine-tune the traction control, wheelie control and cornering ABS settings. It is the sort of setup that gives experienced riders more freedom to push harder on track without completely turning everything off.

2026 KTM 1390 Super Duke RR: Engine and hardware

At the heart of the 2026 KTM 1390 Super Duke RR is the 1,350cc LC8 V-twin engine with camshift technology. It makes 187bhp and 145Nm of torque and comes paired with a six-speed gearbox and a hydraulically operated slipper clutch. KTM has also thrown in a titanium Akrapovic slip-on exhaust as standard, which helps cut weight and should make this V-twin sound even angrier than the regular Super Duke.

The hardware package on the 2026 KTM 1390 Super Duke RR is just as serious as you would expect from a limited-run track bike. Up front, it uses 48mm WP APEX Pro 7548 closed-cartridge forks, while the rear gets a WP APEX Pro 8750 shock with high and low-speed compression adjustment.

Braking comes from Brembo HyPure monobloc four-piston callipers biting on 320mm discs at the front, while the rear uses a twin-piston setup. Put simply, this thing has all the bits needed to handle fast laps and hard braking.
