2026 KTM 1390 Super Duke RR, Most Insane Duke

Powering the 2026 KTM 1390 Super Duke RR is the same 1350cc LC8 V-twin engine found in the standard Super Duke R. Although KTM has further refined it with its latest CAMSHIFT technology. The 75-degree liquid-cooled V-twin develops 190 PS and 145 Nm of torque.

KTM claims the motorcycle now offers an almost 1:1 power-to-weight ratio. As the motorcycle weighs just 189 kg (dry) which makes it 11 kg lighter than the standard Super Duke R. It is possible from the use of carbon-fibre body panels, forged wheels, a cast aluminium and carbon rear subframe, and a standard titanium Akrapovic slip-on exhaust.

The 2026 Super Duke RR uses a chromium-molybdenum steel trellis frame paired with premium WP Pro suspension components. Up front is a fully adjustable WP Pro 7548 closed-cartridge fork, while the rear gets a WP Pro 8750 monoshock with separate high and low-speed compression adjustment, rebound adjustment and hydraulic preload adjustment. Suspension travel stands at 130 mm at the front and 140 mm at the rear.

Braking hardware has also been enhanced for the Super Duke RR. With dual 320 mm front discs and Brembo monobloc calipers, while the rear uses a 240 mm disc with a twin-piston caliper. KTM has also fitted Michelin Power GP hypersport tyres as standard.

Visually, the RR is immediately distinguishable from the standard Super Duke R. It features a more aggressive front end with a revised LED headlamp, additional carbon-fibre detailing and tank-mounted winglets. Seat height can be adjusted between 837 mm and 847 mm. While the 17.5-litre fuel tank remains unchanged from the standard bike.

KTM has also introduced an all-new 8.8-inch TFT touchscreen display on the 1390 Super Duke RR. It also includes offline navigation, telemetry functions, lean-angle and G-force monitoring, and an integrated lap timer. There are eight ride modes available as standard including Street, Sport, Rain, Track, three Custom modes and the new ‘Beast Mode’. In Rain mode, output is reduced to 130 PS for improved control, while Beast Mode strips away nearly all rider aids and leaves only the speed readout visible on the display!
