The SC-Project S1 exhaust is a Race Replica muffler and resonator, meticulously engineered for performance and style. Built by SC-Project, an Italian manufacturer with deep roots in MotoGP, Moto3, Moto2, and Superbike racing, this exhaust system is born from extensive experience at the highest levels of motorsport. The S1 is designed to push performance limits, utilizing technology directly derived from their World Superbike racing endeavors. Its silencer body boasts a conical shape that is crucial for maintaining proper back pressure and ensuring optimal ground clearance, even during extreme lean angles. Key features include a carbon fiber heat shield for protection and aesthetics, and bike-specific mounting hardware is included for a streamlined installation. The product comes with a 24-month factory defect warranty, underscoring SC-Project's commitment to quality. It is important for customers to confirm fitment before purchase.
