In order not to waive the performance and the unmistakable sound of the “Trofeo” full-system with SC1-R silencer, the SC-Project R&D department has developed the EURO 5 approved system for your Aprilia RS 660.  

The full system is equipped with a pre-chamber with a solid design, in line with the unique style of this Aprilia. Thanks to the catalyst inserted in the pre-chamber, it is possible to obtain the best performance always in compliance with the European regulations for street use.

Available with SC1-R silencer in titanium, the product has been made with the same accuracy and technical features as the racing system: T.I.G. welding performed in a controlled environment and bushings CNC machined from solid that guarantee perfect couplings. Made entirely of AISI 304 stainless steel, it was designed for the use of original lambda probes.

The kit is enriched with a dedicated carbon fiber protection and single-seat bracket in black anodized aluminum.
