Engine: 947 cc, 130 hp, 103 Nm – Tuned for Torque, 100 Percent Throttle Opening, 60,000 km Valve Checks

The 947 cc LC8c parallel twin has been specifically calibrated for the RC R. Compared with the 990 Duke, the throttle valves open to 100 percent, the airbox is larger, and the mapping is tuned for aggressive use. The result is 130 hp at 9,500 rpm and 103 Nm at 6,750 rpm. In character, it remains unmistakably a parallel twin: strong from low revs and less linearly rev-hungry than an inline-four. This is not a screaming four-cylinder, but a twin that makes its presence felt from around 3,000 rpm.

The valve-clearance interval has been doubled from the 990 Duke’s 30,000 km to 60,000 km, significantly reducing long-term maintenance costs. Oil changes are due every 15,000 km. Ride-by-Wire, twin ignition and Euro 5+ are standard. The centrally mounted silencer is stainless steel, and fuel capacity is 15.7 liters.

Suspension and Brakes: Brembo HyPure, WP APEX, Progressive Linkage

The brakes are the RC R’s technical highlight. Brembo HyPure four-piston radial calipers are paired with a Brembo MCS radial master cylinder with adjustable engagement point and lever reach. Performance is excellent, with clear engagement and consistent bite. At the rear is a single-piston caliper working on a 240 mm Galfer disc.

The 48 mm WP APEX USD fork provides 147 mm of travel, with 30 clicks each for compression and rebound and three turns of preload. The rear shock offers 134 mm of travel, 30 clicks of low-speed compression, three turns of high-speed compression and 30 clicks of rebound. The suspension is good rather than outstanding. More important is the new progressive linkage at the aluminum swingarm, used for the first time on an LC8c model, which noticeably improves rear-tire traction feel.

Aerodynamics: 13.6 kg of Downforce at 240 km/h – Design Lost, Physics Won

The RC R winglets are not a styling exercise. KTM’s engineers produced test data showing roughly 13.6 kg of downforce at 240 km/h, and management decided that function should beat form. Inspired by the RC16 MotoGP bike, the winglets reduce front-end lift at high speed and improve stability under braking. On the road the effect is harder to quantify, but visually they give the KTM an unmistakable identity.

Electronics: Four Standard Modes, Three Optional Track Configurations, 6D IMU

Rain, Street, Sport and Custom are standard. Three additional Track/Custom configurations are optional, including Slip Adjuster, which can be changed while riding. Traction control offers eight levels. Cornering ABS, Supermoto ABS, a 6D IMU and Wheelie Control are standard.

The 8.8-inch landscape TFT is unusually large for the class. It offers touchscreen operation, anti-reflective and fingerprint-resistant glass, split-screen layouts, real-time telemetry for lean angle, acceleration, deceleration and throttle position, offline GPS navigation, KTM Connect and USB-C.

Ergonomics: Sporty but Surprisingly Moderate

The aluminum clip-ons sit below the upper triple clamp but are not excessively low, and they are wider than many superbike bars. The tank provides six contact zones for active body positioning. Footpegs can be mounted in Street position or moved 25 mm rearward and 17 mm upward for Track use. Seat height is 845 mm, ground clearance 163 mm and ready-to-ride weight 195 kg.

There are compromises. Heat in city traffic is noticeable around the rider’s upper body. The front brake requires slightly more lever effort than some testers expected, and front-end feedback at the limit is somewhat restricted.

Handling: Stability Rather Than Hyper-Agility, Torque Rather Than High-Rpm Drama

The RC R is not a replacement for a 600-class inline-four. A 1,481 mm wheelbase is long for a supersport machine, and 98.5 mm of trail favors stability rather than hyper-aggressive turn-in. The RC R prefers stable lines, late braking and early corner exits driven by the parallel twin’s torque wave. This separates it from a Yamaha R9 or Ducati Panigale V2 – not worse, simply different.

The Yamaha R9 costs EUR 13,699 with 119 hp, while the Ducati Panigale V2 starts at EUR 16,590 plus ancillary charges with 120 hp. At EUR 15,490, the RC R sits between them while including Brembo HyPure brakes and Michelin Power Cup 2 tires as standard.

Track Version and RC R Cup 2026

KTM has also announced a lighter, more powerful Track version without road homologation. A German price had not been officially communicated at the editorial deadline. In parallel, KTM launched the RC R Cup for 2026, a dedicated racing series in which standard production models are eligible to compete.

Cost: EUR 15,490 Plus Ancillary Charges

For EUR 15,490, the RC R includes Brembo HyPure brakes, a Brembo MCS radial master cylinder, Michelin Power Cup 2 tires, the 8.8-inch touchscreen TFT with offline navigation, 130 hp, a 6D IMU, MotoGP-inspired winglets, progressive rear-suspension linkage, 15,000 km service intervals, 60,000 km valve-clearance checks and up to four years of Premium Manufacturer Warranty.

Optional Track software packages cost extra. Demo Mode allows all software options to be tested free for the first 1,500 km. Production takes place in Mattighofen, Austria. Warranty coverage requires scheduled servicing at an authorized KTM dealer.

Verdict

Nearly fifteen years after KTM’s last road-going supersport, the 990 RC R brings the brand back with a very distinct interpretation of the class. It is a parallel-twin supersport with torque-rich character, a stable front end and surprisingly moderate ergonomics. The brakes are the best part of the package. The suspension is good, but not the benchmark. The display is the largest in the class. And at EUR 15,490, the price is right.
