DescriptionThe whole story

Born from SC-Project's direct collaboration with the Aprilia Racing Factory Team and shaped by MotoGP development, the SC1-R full titanium exhaust system in the 250mm configuration is the definitive performance upgrade for the RSV4 1100 Factory. Every weld, every contour, and every gram of this system reflects a philosophy of uncompromising race-derived engineering — purpose-built for riders who demand the last fraction of performance on track.

Key Features

  • Full 4-2-1 titanium construction across headers and silencer, delivering a weight saving of 4.2 kg over the OEM system
  • Measured gains of +9.8 hp and +7.5 Nm of torque (without dB-killer, at 8,700 rpm) for a transformative on-track experience
  • Aggressive race soundtrack: 106 dB at 6,500 rpm with dB-killer fitted; 113 dB at 6,500 rpm without
  • Precision TIG-welded titanium headers in a controlled environment for consistent quality and extreme heat resistance
  • Carbon end cap, carbon heat shield and carbon single-seat silencer bracket for an unmistakably race-focused aesthetic
  • Compatible with original lambda sensors — plug-and-play installation with no sensor modification required

Design, Finish and Heritage

SC-Project's heritage in top-flight motorsport is written into every detail of the SC1-R. The titanium's natural raw finish — a hallmark of the finest racing exhausts — develops a characteristic heat tint over time, marking the system as genuinely functional rather than merely decorative. The 250mm silencer profile is lean, purposeful and immediately recognisable as track equipment. Carbon fibre accents on the end cap, heat shield and bracket reinforce the premium character without adding unnecessary mass. This is not a road-legal catalogue part dressed up in race clothing; it is a genuine piece of Aprilia Racing DNA made accessible to the privateer.

Performance and Build Quality

The optimised 4-2-1 exhaust routing improves scavenging across the rev range, sharpening throttle response and pulling harder from mid-range through to the top end. The titanium headers, precision TIG-welded in a controlled atmosphere, resist the thermal cycling that destroys lesser systems over a season of hard track use. Metal-capped sealing springs at every joint maintain a gas-tight connection under sustained high-temperature loading, ensuring the performance figures hold lap after lap. The 250mm canister is sized specifically for maximum power without a dB-killer, making it the choice for closed circuits where sound regulations are either absent or lenient.
