The Akrapovic Slip-On Line is a bolt-on titanium muffler for the 2025 Kawasaki Z900 and Z900 A2, in a new conical profile with a carbon fibre end cap.
Kawasaki revised the Z900 for 2025 along with its exhaust, so this is a part for the new machine rather than a carry-over from the 2017-2024 bike.
The conical shape is shorter and more aggressive than the outgoing design, and Akrapovič describe the result as louder, deeper and crisper than the road-legal alternative — which it is, because this version is not type approved.
This muffler is NOT EC/ECE type approved and does not meet emissions requirements for street or highway use. It is intended for closed-course use or for markets where approval is not required.
If you need a road-legal option for the same bike, Akrapovič's carbon Slip-On Line (S-K9SO11-HZC) is EC/ECE approved and we stock it — same 2025 Z900, different legal standing.
Fits the 2025 Kawasaki Z900 and Z900 A2. The 2017-2024 Z900 takes a different muffler. Developed and tested on EU-specification machines; fitment and performance may vary on other market specifications.
