SC Project S1 Matt Black Titanium Silencer KTM 1390 Superduke R 2024-25

The SC Project S1 Matt Black Titanium Silencer has been engineered for riders who want the ultimate racing performance from their KTM 1390 Super Duke R, also known as “The Beast.”

Built with a ceramic-coated titanium body, carbon fibre end cap, and SC-Project’s distinctive racing sound, the S1 is both a technical and aesthetic upgrade.

Delivering an outstanding weight reduction of -60% compared to the OEM system, the S1 saves 1.9 kg, improving agility and handling. Performance is equally impressive, with +4.5 hp and +3.5 Nm of torque at 9000 rpm, alongside consistent gains throughout the low and mid range. Designed for race use only, the silencer includes a removable dB-killer, offering two sound profiles: 98 dB at 5000 rpm with the baffle installed, or a more aggressive 102 dB without it.

The conical design, SC-Project laser-etched logo, and a sleek ceramic painted matt black finish elevate the bike’s aggressive styling. Handcrafted TIG welds showcase Italian craftsmanship, while the included carbon fibre heat shield adds a premium touch. Installation is fully plug-and-play with no ECU remapping required.
