1390 SUPER DUKE R (2024)

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.
