DescriptionThe whole story

This is the road-legal slip-on for the full-power Z900 of 2020 to 2024, and the first thing to say about it is what we cannot tell you: Akrapovic publishes no weight and no dyno figures for this part number.

Key Features

  • EC and ECE type approved, plus EPA for the United States
  • High-grade lightweight titanium
  • Smaller, shorter, conical design, aimed at the bike's appearance
  • For the full-power Z900, not the A2 version
  • A big weight saving over the standard silencer, per Akrapovic
  • No entry in the vehicle documents required

The Figures We Do Not Have

Akrapovic's technical data for S-K9SO6-HZT is empty: no stock weight, no fitted weight, no power or torque measurements. Its description says the exhaust offers a big weight saving and a performance increase, without putting numbers to either.

We could estimate from the sibling parts — the A2 version of this silencer saves 2 kg from 4.2 — but we are not going to publish a guess as though it were a measurement. If the exact figures matter to your decision, ask us and we will request them from Akrapovic before you order.

What Is Certain

The approval. EC and ECE type approval are both recorded, along with EPA certification. That means the exhaust needs no entry in the vehicle documents and no individual inspection anywhere in Europe — and on a road-registered Z900 that is the property most owners are actually buying.

Full Power, Not A2

Akrapovic builds S-K9SO10-HZT for the restricted A2 Z900 of the same years, and this one for the 92 kW machine. They look identical and are not interchangeable in terms of what Akrapovic measured.

The kilowatt figure in the registration document decides. 92 kW is this part; 70 kW is the other.

Why We Say So Rather Than Estimate

It would be easy to write "around 2 kg saved" here and nobody would check. But a figure printed on a product page becomes the figure a customer quotes back, and one invented from a sibling part is not a measurement.

Akrapovic has the data internally; it simply has not published it for this number. Ask and we will get it.

Five Model Years

Kawasaki kept the Z900's exhaust mounting unchanged from 2020 to 2024 before the 2025 redesign, so one silencer covers the whole middle generation of the model.

The Approval Is the Product

Most slip-ons in this catalogue are bought for weight or sound and give up the type approval to get there. This one keeps it. On a Z900 ridden to work every day, that is the property worth paying for — and it is the one Akrapovic does document.

Shorter and Conical

Akrapovic describes the shape as smaller, shorter and conical, chosen for how the bike looks. Kawasaki's standard Z900 silencer is a large rectangular box; a compact cone in its place is the single most visible change available to this motorcycle.

Fitment and Compatibility

S-K9SO6-HZT covers the Kawasaki Z900 full-power version from 2020 through 2024. The 2025 machine takes S-K9SO11-HZT or S-K9SO11-HZC.
