The Akrapovič Slip-On Line exhaust for the 2025-2026 Kawasaki Z 900 replaces the standard silencer with a titanium unit. It cuts weight and delivers a performance increase, according to Akrapovič’s measurements.
The conical silencer follows the bike’s lines and has a carbon-fibre end cap. Its sound is louder, deeper and crisper than the standard exhaust.
- Power: +0.8 kW (+1.1 metric hp) at 9,000 rpm on Akrapovič’s test bike.
- Torque: +0.9 Nm at 6,800 rpm in the same tests.
- Weight: 1.5 kg versus 3.93 kg for the standard exhaust, a reduction of 61.8%.
- Fitting: plug-and-play installation takes approximately 30 minutes, with no remapping required.
- Noise insert: no dB killer is included.
- A2 version: also fits the 2025 Z 900 A2.
- Headers: those shown in the photographs are optional.
This exhaust is not type-approved and does not meet emissions requirements for road or highway use. It is intended for track days or markets where EC/ECE type approval is not required. It was developed and tested on an EU-specification bike; fitment and performance may vary on versions for other markets.
