DescriptionThe whole story▼
Shaped by decades of MotoGP and World Superbike engineering, the SC-Project SC1-R slip-on silencer in carbon brings a genuinely race-bred aesthetic to the Aprilia RSV4 1100 Factory. The hydroformed carbon fibre end-cap and hand-finished construction are as visually striking as they are functionally superior — this is the exhaust upgrade that changes the character of the bike from every angle.
Key Features
- Hydroformed carbon fibre end-cap delivers unmatched aerodynamic form and a distinctive racing silhouette
- Weight saving of 1.7 kg over the stock exhaust — SC-Project unit: 4.3 kg versus OEM: 6.0 kg — for sharper handling and improved power-to-weight ratio
- Titanium link pipe and CNC-machined titanium collars ensure precise fitment and exceptional heat resistance
- T.I.G.-welded joints throughout guarantee long-term structural integrity under sustained high-rpm use
- Plug-and-play compatibility with the RSV4's exhaust valve system — no modification required
- Includes a removable dB killer for tunable volume between road and trackday use
- Euro 4 homologated — fully road-legal with homologation card included
Design, Finish and Heritage
SC-Project's racing pedigree is evident in every detail of the SC1-R. The carbon fibre canister is not simply a cosmetic choice — the hydroformed end-cap is engineered for aerodynamic efficiency while giving the RSV4 1100 Factory an unmistakably aggressive stance. SC-Project's laser-etched logo and inclusion of MotoGP-style decals are the finishing details that distinguish a factory-grade installation from an aftermarket bolt-on.
The titanium link pipe connects with T.I.G.-welded precision, and the CNC-machined titanium collars ensure that every joint sits flush and secure. This is the kind of craftsmanship that earns SC-Project supply contracts with factory racing teams — brought directly to a road-registered machine.
Performance and Sound
Across the full rev range of the RSV4 1100 Factory's V4, the SC1-R improves both power delivery and torque response, translating to sharper acceleration and a more responsive throttle character. The 1.7 kg mass reduction lowers the centre of gravity and reduces unsprung rotating mass, with a noticeable improvement in agility on both road and circuit.
The sound signature is deep, purposeful and unmistakably Italian — a broad V4 bark that rewards hard riding without crossing into anti-social territory on the public road. With the dB killer fitted the note remains rich and sonorous at legal volumes; remove it for trackday use and the SC1-R opens up to a full racing soundtrack.
