DescriptionThe whole story▼
Developed in direct collaboration with the SC-Project racing division, the SC1-R slip-on silencer brings genuine circuit-derived technology to your Kawasaki ZX-10 R or ZX-10 RR — and crucially, it does so with full Euro 4 road-legal approval and EC type-approval included as standard. This is not a compromise between road compliance and race performance; it is both, without concession.
Key Features
- Euro 4 road-legal with EC type-approval — ride legally on public roads without compromise
- Hydroforming technology delivers aerodynamic efficiency and a purposeful, sculpted silhouette
- Asymmetric diamond-section carbon construction provides a racing aesthetic unique to the SC1-R line
- Hand-laid T.I.G. welds executed in a controlled environment for absolute structural integrity and longevity
- High-temperature acoustic damping material optimises both sound character and thermal performance
- Meaningful weight saving of 0.1 kg over the stock unit for a more agile feel through transitions
- Full-titanium connector fitting with T.I.G. technology for corrosion resistance and reduced overall mass
Road-Legal Racing Provenance
The SC1-R carries the Euro 4 homologation and EC type-approval that many rival aftermarket exhausts cannot offer. For ZX-10 R and ZX-10 RR owners who use their machine on the road as well as the track, this certification removes any ambiguity about legality. The approval is included in the package — there is no separate documentation to source or additional cost to absorb.
SC-Project's racing department shaped every dimension of the SC1-R around lessons learned in top-level competition. The hydroformed canister is not simply a visual exercise; it contributes to optimised exhaust gas flow that translates into a perceptible gain in mid-range response and a deeply characterful exhaust note — aggressive enough to announce your intent, controlled enough to pass noise checks.
Materials and Construction
Every component in the SC1-R reflects SC-Project's refusal to use anything other than competition-grade materials. The connecting pipe is machined from solid titanium, keeping thermal mass low and aiding weight reduction. The end cap — available in natural carbon or titanium finish — is heat-resistant and aerodynamically profiled to complete the visual package. Welds are performed in a shielded environment to prevent contamination, producing joints that are as strong as they are clean. The internal acoustic damping compound is selected specifically for high-temperature durability, ensuring the sound signature remains consistent across the life of the silencer.
Fitment and Compatibility
The SC1-R Slip-On in part number K22A-T90 is engineered as a direct-fit replacement for the following Kawasaki models:
