S1-GP Full System Exhaust by SC-Project

Unlock race-developed performance with the SC-Project S1 Exhaust—a premium Italian system engineered by a manufacturer proven at the highest levels of motorcycle racing. With development roots in MotoGP, Moto2, Moto3, and Superbike World Championship, SC-Project uses real-world competition feedback to refine exhaust flow, fit, and durability for aggressive street and track riders. 

The S1 is a tapered, race-inspired exhaust designed around World Superbike technology for strong performance and an unmistakable track look. A large-diameter outlet promotes enhanced exhaust flow, while the conical silencer body helps maintain proper back pressure—supporting responsive throttle feel and a crisp, performance-focused character. The S1’s conical profile is also built to improve ground clearance, giving riders more confidence during extreme lean angles.
