Race-Inspired Engineering

The SC1-R is more than just an aftermarket exhaust—it stems directly from SC Project’s deep involvement in professional motorcycle racing. Teams in MotoGP, WorldSBK, and Moto2 trust SC Project for high-performance exhaust systems, and the SC1-R reflects that pedigree.

This titanium version features a conical shape that enhances both function and aesthetics. It improves exhaust flow, reduces weight, sharpens throttle response, and produces a distinct, race-ready sound. The sleek titanium body, paired with a carbon fiber end cap, blends lightweight materials with an aggressive finish that complements the KTM Duke’s edgy design.

Real Performance Gains

The SC1-R Titanium doesn’t just look fast—it delivers noticeable performance improvements. By reducing backpressure and increasing exhaust gas exit speed, it allows your engine to breathe freely. That translates to quicker throttle response, stronger mid-range torque, and a more engaging ride across the RPM range.

Most riders feel the difference between 4,000 and 8,000 RPM—the zone where the LC8c twin delivers its best punch. Even without an ECU remap, the Duke becomes noticeably livelier. Pair it with a high-flow air filter or ECU tune, and the performance boost becomes even more impressive.

Whether you’re hammering through twisties or accelerating onto a straight, the SC1-R gives your Duke a sharper, more urgent feel.

Sound That Demands Attention

The SC1-R Titanium brings a soundtrack that matches its performance. At idle, the exhaust emits a deep, mechanical growl. Twist the throttle, and it roars with an aggressive bark that intensifies as the revs climb. Downshifts produce satisfying pops and crackles that turn every gear change into an experience.

Riders who remove the included dB killer will hear the SC1-R at full volume—raw, loud, and track-ready. It’s built for those who want their bike to be heard as well as felt. For more subdued environments, reinstalling the dB killer tames the volume without sacrificing character.

Titanium Build & Weight Savings

Titanium’s strength, heat resistance, and low mass make it a perfect material for performance exhausts—and SC Project puts it to full use here. The SC1-R Titanium drops several kilograms compared to the bulky OEM system, which includes a large muffler and catalytic converter.

That weight reduction boosts acceleration, braking, and agility. On a bike like the Duke, where responsiveness is everything, less weight means more control and better dynamics in corners. Every weld is precision TIG-welded, and CNC-machined mounts ensure a perfect fit with factory hardware.

---

Straightforward Installation

Installing the SC1-R Titanium is quick and simple. As a slip-on system, it attaches directly to the stock mid-pipe and mounts to the factory points. There’s no need to cut, weld, or modify anything.

With basic tools and a bit of mechanical know-how, most riders can complete the installation in under an hour. It’s one of the easiest upgrades to perform—and one of the most noticeable.

Know Before You Ride: Street Use and Compliance

The SC1-R Titanium is engineered for performance, not necessarily for street legality. It doesn’t include a catalytic converter, and the full-volume sound may exceed local noise limits—especially without the dB killer.

Before installing, always check your region’s noise and emissions regulations. SC Project does offer optional dB killers and, in some markets, homologated versions that bring the system closer to street-legal specifications.
