The Akrapovic Slip-On Line is a bolt-on titanium muffler for the 2017-2024 Kawasaki Z900, in a short conical profile with a hand-built carbon fibre end cap.
The Z900 is a naked bike, which means the canister is fully exposed and its shape is part of the motorcycle's silhouette. Kawasaki's factory unit is long and bulky because emissions compliance demands the volume; the Akrapovič is visibly shorter and smaller.
It is homologated, so it is road legal as supplied, and being a slip-on it leaves the headers and fuelling untouched.
Fits the 2017-2024 Kawasaki Z900. Kawasaki revised the Z900 for 2025 and that machine takes a different muffler (S-K9SO11-HZC), which we also stock — check your model year before ordering. The Z900RS and Z900RS Cafe also use their own exhaust routing and a different part again.
