KTM 1390 SUPER DUKE R (2024-2026) S1 titanium exhaust, matt black

Engineered and designed to let you feel every beat of the KTM 1390 Super Duke R, the S1 racing muffler is the perfect combination of lightness, design and SC-Project signature sound.

For “The Beast”, the S1 racing muffler allows an outstanding weight reduction of -60% (-1.95 kg if compared to the OEM exhaust) and to get an incredible maximum gain of 4.5 hp at 9000 rpm and 3.5 Nm of torque at 9000 rpm, together with a stable improvement of power and torque delivery in the low and mid range.

In this race-use-only configuration, the S1 silencer comes with a removable baffle. This solution will give you the choice between a loud (but acceptable) sound output of 98 dB at 5000 rpm – with dB-killer installed – and a louder voice of 102 dB at 5000 rpm without dB-killer.

The conical body shape enriched by SC-Project lasered logo and the elegant carbon fibre end cap, make the S1 silencer a benchmark in terms of aesthetic and sound emotion. The absolute top quality finish of the ceramic painted matt black outer sleeve and the handcrafted TIG weldings, are a pure joy for the look of the bike.

The kit is completely plug and play and it is enriched by a specific high quality carbon fibre heat shield. ECU remapping is not necessary.
