SC Project Exhaust KTM Duke 890 / R S1-GP Silencer 2020+


The S1-GP silencer is a perfect choice for motorbike enthusiasts who want to achieve a sporty and stripped-down look for their KTM 890 Duke.

This silencer is available with a titanium tapered body that not only looks great but is also highly durable. The S1-GP silencer features bracket and fitting welding with TIG technology, which ensures that it is securely attached to the bike and will not come loose even during high-speed rides. Additionally, the machined insert bushings turned from solid provide impeccable build quality, ensuring that the silencer remains stable and doesn’t vibrate or wobble.

The tapered body of the S1-GP silencer, along with the diameter of the output, specific internal soundproofing, and the setup for housing the internal dB-killer, delivers a full and satisfying sound that every rider craves. The sound is neither too loud nor too soft, striking the perfect balance between power and comfort. The kit comes with carbon heat protection.

In summary, the S1-GP muffler is an excellent choice for motorbike enthusiasts who want to enhance the look and sound of their KTM 890 Duke.
