KTM 990 RC R 2026

KTM 990 RC R 2026

The KTM 990 RC R is far more than just a new model. It is KTM's long-awaited return to the roots of the true supersport concept. Despite intensive involvement in Moto GP, there has been no successor to the legendary RC8R for almost 15 years. With the new RCR 990, however, the supersport wind is blowing through Mattighofen again. With its successful features, it combines the precision of a racing bike with suitability for everyday use and brings some new innovations. With an easy-to-control 130 Horsepower, good electronics, stable riding performance and balanced ergonomics, it should not only delight KTM fans, but also represent serious competition for the newly established Supersport class. With a starting price of €17,399 (A) or €15,490 (D), it is also in the middle between the R9 and Panigale V2 and will therefore attract the attention of buyers. And there is another ace up the sleeve for pure racetrack fans. From the beginning of 2026, there will also be a track version of the RCR 990. All parts required for road approval will be omitted and the bike will be trimmed even more for track use with racing fairing and its own electronics package. Ready to race, in other words.
