Show original supplier description
The SC-Project S1 exhaust system is a high-performance upgrade for the Triumph Street Triple 765 R/RS, born from the manufacturer's extensive racing experience in MotoGP, Moto3, Moto2, and Superbike championships. This tapered exhaust features a large outlet diameter for improved airflow and is engineered with a conical silencer body. This design ensures proper back pressure, enhances performance, and provides optimal ground clearance for extreme lean angles. Constructed from aeronautical-grade materials, the S1 exhaust system is built for durability and performance. It includes all necessary bike-specific exhaust mounting hardware for a direct fit. The system is designed with a racing-inspired aesthetic and comes with a 24-month factory defect warranty. For optimal performance gains, ECU remapping is recommended after installation. The SC-Project S1 exhaust is compatible with the stock bellypan, simplifying integration with your motorcycle's existing setup.
