2026 KTM 990 Duke R First Look: More Power, Better Spec

The KTM 990 Duke R takes KTM’s 947cc middleweight naked platform and turns up nearly every part that matters for performance. Sitting above the 990 Duke and below the larger 1390 Super Duke R, the 990 Duke R combines more power with revised suspension, stronger brakes, more aggressive ergonomics, track-oriented tires, and expanded electronics. First shown at EICMA in 2024, the production bike has now joined KTM’s US lineup with an MSRP of $13,399.

Importantly, this isn’t a clean-sheet replacement for the 990 Duke. The R keeps the same basic LC8c parallel-twin engine, tubular steel frame, aluminum subframe, and much of the underlying platform. Instead, KTM has concentrated its changes on extracting more performance from the existing package, resulting in a 419-pound fully fueled naked bike aimed squarely at riders who want more track-capable hardware without stepping up to the 1390 Super Duke R.

The Same LC8c Twin Gets A Little More Punch

At the center of the 990 Duke R is KTM’s liquid-cooled, DOHC 947cc LC8c parallel twin. Revised engine mapping raises output from the standard 990 Duke’s 123 horsepower to 126 horsepower, at 9,500 rpm. Peak torque remains 76 lb-ft at 6,750 rpm, while the rev limit sits at 10,500 rpm. Power goes through a six-speed transmission featuring a slipper clutch.

The suspension changes are more extensive than the engine revisions. A fully adjustable 48 mm WP Apex open-cartridge inverted fork replaces the standard 990 Duke’s 43 mm unit, with KTM claiming 34% more stiffness. New forged aluminum triple clamps accompany the fork, while the rear gains a linkage-equipped WP Apex shock with a linear spring. Travel measures 5.63 inches up front and 5.51 inches at the rear.

The R also gets more aggressive ergonomics to match its positioning. Its footpegs sit 33 mm farther rearward and 12.5 mm higher, while the handlebar position is adjustable. The bike is homologated for two people but comes from the factory as a single-seater, with passenger equipment available separately.

Bigger Brakes And Much Stickier Rubber

Owners will also find a sizable brake upgrade. The front uses Brembo Stylema four-piston radial-mount monoblock calipers with an adjustable Brembo master cylinder and twin 320 mm floating discs. The standard 990 Duke uses 300 mm front rotors, so the R gains both larger discs and higher-spec calipers. A 240 mm disc with a single-piston floating caliper handles braking at the rear.

The R rolls on lightweight 17-inch cast aluminum wheels derived from the 1390 Super Duke R platform. KTM wraps them in Michelin Power Cup 2 tires measuring 120/70 R17 up front and 180/55 R17 at the rear. That choice alone makes the R’s intentions fairly obvious, since the Power Cup 2 is a road-legal tire developed with aggressive road and track use in mind.

The Electronics Get A Major Interface Upgrade

One of the most visible updates is KTM’s 8.8-inch landscape-oriented TFT display. It supports split-screen functionality, connectivity, and navigation, while a redesigned switchgear layout provides another way to navigate the bike’s controls without relying exclusively on touch inputs.

Rain, Street, Sport, and Custom riding modes are standard. KTM also offers additional Track and Custom configurations through optional software packages. Track Mode opens up greater control over throttle response and electronic intervention, including five levels of wheelie control plus the option to disable it. Launch control is included with the optional Track Pack.

The braking electronics also gain Sport ABS and Supermoto+ ABS settings, giving the R additional configuration beyond the standard street-oriented modes. KTM allows owners to sample optional software functions during an initial demo period before deciding whether to purchase them permanently.

A More Serious 990 Without Going Full Super Duke

The 2026 KTM 990 Duke R sits between the regular 990 Duke and the more powerful 1390 Super Duke R, retaining the 947cc twin and 419-pound fully fueled weight while adding more advanced suspension, stronger brakes, track-oriented tires, revised geometry, and expanded electronics. At $13,399, it gives riders a more focused version of KTM’s middleweight naked without requiring the jump to the larger Super Duke platform.
