KTM's 2026 flagship street Super Duke, a 350-unit run that the page calls the undisputed flagship of the KTM street range. It is a more extreme 1390 Super Duke R, with about 11 kg removed, a stiffer chassis, carbon-fibre parts, MotoGP-derived WP suspension, forged wheels and an 8.8-inch TFT with track-mode lap timing. It also has winglets around the tank for added downforce.
