KTM 990 RC R Review (2026): Specs, 128 HP & 280 km/h Track Test
KTM's purebred middleweight supersport weapon. Engineered with a 947cc LC8c parallel-twin (128 hp / 103 Nm), aerodynamic MotoGP front winglets, WP APEX Open Cartridge suspension, Brembo Stylema brakes, GP reverse-shift pattern, and $16,499 USD MSRP.
The Strengths
- High-revving 947cc LC8c parallel-twin generating 128 hp with explosive mid-range punch and 103 Nm torque
- Wind-tunnel engineered aerodynamic MotoGP front winglets generate real downforce for extreme high-speed braking stability
- Fully adjustable 43mm WP APEX Open Cartridge forks and APEX shock with race-spec high/low speed compression tuning
- Track-grade Brembo Stylema radial monobloc calipers clamping twin 320mm floating discs with Supermoto ABS mode
- Ergonomically tuned clip-ons, adjustable rearsets, and reversible GP shift pattern for track-day conversion
The Compromises
- Aggressive forward-canted supersport ergonomics place substantial load on wrists during prolonged city commuting
- Firm track suspension setup transmits sharp urban expansion joints directly to the rider
- Track-focused focus sacrifices pillion accommodation and luggage mounting options

KTM 990 RC R: 128 HP LC8c Dyno, MotoGP Winglet Telemetry & Track Audit
Ever since the legendary RC8 1190 concluded its production run, sportbike enthusiasts have clamored for a dedicated large-displacement supersport from Mattighofen. For 2026, KTM answers with the 990 RC R. Compare its chassis agility against naked siblings in our KTM Duke 390 Gen 3 review and Duke 390 telemetry review, explore litre-class superbikes in the BMW S1000RR review, and see middleweight Italian roadsters in our 2026 Ducati Monster V2 review.
1. 947cc LC8c Parallel-Twin & 128 HP Dyno Curve
The 990 RC R is propelled by an upgraded 947cc LC8c parallel-twin engine with a 285-degree firing interval. Pumping out 128 hp at 9,500 RPM and 103 Nm of torque at 6,750 RPM, over 80% of peak torque is on tap from just 4,000 RPM. Compare its rapid acceleration against automated hyper-nakeds in our Yamaha MT-09 Y-AMT review and parallel-twin sport competitors in the Suzuki GSX-8R review.
2. MotoGP Aero Winglets & WP APEX Suspension
Developed using KTM's RC16 MotoGP aerodynamic simulations, the front winglets reduce front-wheel loft under aggressive track corner exits while improving trail-braking stability. The 43mm WP APEX Open Cartridge front forks provide compression and rebound adjustment, paired with Brembo Stylema calipers.
