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

The SC Project S1 Titanium Silencer is designed for riders who demand the ultimate racing performance from their KTM 1390 Super Duke R, also known as “The Beast.”

 Combining lightweight construction, cutting-edge design, and SC-Project’s unmistakable racing sound, the S1 transforms your machine into a track-ready weapon.

With an outstanding weight reduction of -60% compared to the OEM system, the S1 saves 1.9 kg, significantly improving agility. Performance is also dramatically enhanced, delivering +4.5 hp and +3.5 Nm of torque at 9000 rpm, along with smoother, more consistent power across the low and mid-range. This racing slip-on is supplied with a removable dB-killer, offering two distinct sound profiles: 98 dB at 5000 rpm with the baffle installed, or a more aggressive 102 dB without it.

The conical titanium body, finished with SC-Project’s laser-etched logo and complemented by a sporty carbon fibre end cap, provides a striking racing look. The silencer also benefits from TIG weldings completed by hand for exceptional build quality and durability. Fully plug-and-play, it requires no ECU remapping and includes a dedicated carbon fibre heat shield for a premium finish.
