Roadsitalia Exhaust
In 2017 Kawasaki closed the Z800 chapter and opened that of the Z900: a generational leap bringing a completely new 948 cc inline four-cylinder, a lighter frame compared to its predecessor and more evolved base electronics. The result is a naked that raises the bar for the segment, with a fuller mid-range delivery and a more direct character compared to the Z800 it replaces. This is not a simple evolution — it is a motorcycle redesigned from the ground up, which quickly won over a wide audience across Europe. For those looking to upgrade the exhaust silencer on this first generation, the exhausts for Kawasaki we manufacture include solutions developed specifically for the Z900 2017-2019.
The sports silencer for the Z900 2017-2019 is a muffler designed to replace the original silencer in its lateral position, leaving the standard headers and connections unchanged. Mounting uses the motorcycle's original fittings without structural modifications, and the kit includes all the hardware necessary for installation. We recommend entrusting the fitting to a qualified mechanic to ensure a correct and lasting result.
The original Z900 silencer is far from lightweight, and replacing it with our sports exhaust produces a tangible weight reduction on the rear lateral area of the motorcycle. The acoustic tone improves in quality and definition, with a fuller and more present voice that enhances the character of the new 948 cc four-cylinder — an engine that has more to say than the Z800, and that expresses it better with a freer silencer. In terms of engine response, more efficient exhaust gas flow management can favour a smoother power delivery and make throttle response more direct under certain riding conditions.
Every exhaust is worked directly in our workshop with handcrafted manufacturing in Lombardy, in the province of Bergamo, to order. Before each dispatch we carry out internal quality control on the finished piece. Direct from the manufacturer sales ensure the absence of intermediaries between our production and the person receiving the product.
Every silencer is supplied with a standard dB killer included in the kit. Removing the dB killer invalidates the product's homologation and is not officially supported. For those who use the motorcycle in contexts requiring greater noise containment — daily urban routes, residential areas, personal preference — the No-Noise option is available: an internally welded filter that further reduces the sound level without significantly affecting the characteristics of the exhaust silencer. It can be selected directly on the product page.
As this involves only the replacement of the silencer, the Z900 2017-2019 ECU does not normally require any remapping. The original system remains in its standard configuration and the modification is contained enough not to cause any electronic issues.
Updated production lead times are always visible at checkout. Once dispatched, you will automatically receive a tracking code to monitor your delivery.
For any technical question — compatibility with your specific version, differences between the available variants, the most suitable configuration for your use — consult our FAQ or contact us via the Contact page or chat. We respond precisely and directly.
Below this description you will find the product list available for the Z900 2017-2019. The differences between variants relate primarily to the shape, material and finish of the silencer. From the product page you can select the No-Noise option from the drop-down menu, view detailed photos and read the full technical specifications to configure your silencer.
