DescriptionThe whole story▼
The Akrapovic Slip-On Line in carbon is the most straightforward upgrade a ZX-10 R or ZX-10 RR owner can make — bolt it onto the original header, gain measurable power, shed real weight, and remain fully road-legal under Euro 5 legislation. It is the rare silencer that delivers on every front without compromise.
Key Features
- Direct fitment onto the original header — no additional modifications required
- Gains 0.5 hp over stock (187.3 hp to 187.8 hp at 10,250 rpm) and adds 0.6 Nm of torque at 10,330 rpm
- Hexagonal silencer body with a carbon fibre outer shell and titanium end cap for a premium finish that is also lightweight
- All internal metallic components are titanium, including the internal structure and the connecting link pipe
- Includes a dB eater for noise-sensitive environments such as trackdays with sound limits or urban riding
- Euro 5 compliant with EC type approval — fully legal for road use throughout Europe
Build Quality and Materials
Akrapovic constructs the S-K10SO27-HRC entirely around titanium where metal is required. The link pipe is titanium, the inner construction of the silencer is titanium, and the end cap is titanium. The outer shell is carbon fibre, giving the unit a purposeful, race-derived appearance that wears well over time and resists corrosion. The hexagonal profile is an Akrapovic signature that improves ground clearance compared with conventional round cans — a practical advantage that matters when you are pushing hard through corners.
Performance and Sound
The power gains are modest but real — 0.5 hp and 0.6 Nm are independently verified figures that sharpen throttle response and improve mid-range pull where everyday riding actually happens. The Akrapovic exhaust note is fuller and more authoritative than the standard silencer across the rev range, without becoming antisocial at low speeds. For riders who need extra flexibility, the included dB eater can be fitted in minutes and brings the unit within most trackday noise limits.
Fitment and Compatibility
This slip-on silencer is designed specifically for the following motorcycles:
- Kawasaki ZX-10 R (2021, 2022, 2023, 2024, 2025)
- Kawasaki ZX-10 RR (2021, 2022, 2023, 2024, 2025)
The unit mounts directly to the original Kawasaki header without any additional brackets or adapters.
