NINJA ZX-4R - RR (2024)

The Kawasaki ZX-4R - RR stands at the peak of its category, thanks to the rpms-hungry 4 cylinders engine.

To allow you to enjoy every high-rev note of this innovative engine in full compliance with Euro 5 regulation, SC-Project developed this specific version of the SC1-S silencer.

Manufactured using high grade titanium, the muffler enhances the agility of the little Ninja thanks to a massive weight reduction of more than -50% (-2.2 kg if compared to the OEM silencer) while upgrading the performance of the engine with a stable improvement of power and torque delivery in the low and mid range.

All the components of the SC1-S are welded with TIG technology (in protected environment) and the internal bushings are CNC machined from solid block: excellent couplings and top quality materials are necessary to offer the best durability, quality and performance.

The silencer’s body is enriched by an exclusive aluminium plate with SC-Project logo, exactly as the exhaust systems of SC-Project’s Reparto Corse.

Installation is 100% plug and play and ECU remapping is not necessary.
