Key points
- The KTM RC 990 is a prototype sportbike powered by the same heavily modified LC8c engine as the KTM 990 Duke Prototype.
- The fairings on the RC 990 clearly hark back to some of KTM’s previous fully faired sports successes, from the RC8 and RC8 C to Team Orange’s RC16 MotoGP machine.
- The riding position is also significantly more aggressive than the one found on the 990 Duke Prototype.
- Engine power figures are expected to top 140 horsepower, with torque as yet unspecified.
- Brembo Stylema calipers are expected to be used, but this is not yet confirmed.
- The headlight is somewhat disguised on this RC 990 prototype.
- Production of the RC 990 is not expected until sometime in 2025.
Details
KTM is working on two prototypes, the KTM 990 Duke Prototype, and the KTM RC 990 Prototype, both spotted testing in Europe. These prototypes share a common heavily modified LC8c engine and are expected to have the same chassis. However, they have distinct differences in appearance and riding positions.
The KTM RC 990 Prototype features fully faired sportbike styling, drawing inspiration from previous KTM models like the RC8, RC8 C, and RC16 MotoGP machine. It is designed to be more aggressive in terms of riding position compared to the KTM 990 Duke Prototype.
Engine
The spy photos and rumours suggest the RC 990 could potentially have engine power figures exceeding 140 horsepower, though specific torque figures are yet to be revealed. Previous prototypes displayed Brembo Stylema calipers, but the ones seen in the recent spy photos are lightly disguised, indicating possible further developments in the braking system.
The headlight of the RC 990 prototype is also disguised to some extent, more so than on the 990 Duke prototype. This suggests that the RC 990’s design might still be subject to changes and refinements.
RC 990
While these spy photos provide insight into the development progress of the RC 990, it is important to note that everything is still speculative at this point. Production of the KTM RC 990 is not expected until sometime in 2025, with the current date being August 2023, bringing us closer to the start of 2024.
Keep in mind that plans and development timelines for motorcycle manufacturers can change, so it’s always best to follow official announcements from KTM to get the most accurate and up-to-date information.
Pros and Cons of the KTM RC 990 prototype
Pros:
- Powerful engine
- Aggressive riding position
- Lightweight chassis
- Brembo Stylema callipers (expected)
- Stylish fairings
Cons:
- Not yet in production
- Expensive
- Aggressive riding position may not be comfortable for everyone

Conclusion
KTM is actively working on the development of two prototypes: the KTM 990 Duke Prototype and the KTM RC 990 Prototype. These motorcycles share the same heavily modified LC8c engine and possibly the same chassis. However, they have distinct designs and riding positions, with the RC 990 being a fully faired sportbike with a more aggressive riding stance.
The spy photos and rumours suggest the RC 990 could potentially have impressive engine power figures, possibly exceeding 140 horsepower, though torque figures are still unknown. Some developments in the braking system, indicated by the Brembo Stylema calipers, are likely, but specifics remain uncertain.
While the RC 990 appears to be in a more advanced stage of development compared to earlier images, it’s still expected that the production version will not be available until sometime in 2025. Given the current date being August 2023, the start of 2024 is getting closer, however, development timelines may shift, and official announcements from KTM will provide the most accurate and up-to-date information.
