Exhausts Kawasaki Z650 2021-2023

The Kawasaki Z650 in 2021 updates the engine to Euro 5 homologation without touching the setup that had made this naked a reference in its category. The mechanics remain those of the proven previous generation — 649cc parallel-twin, steel tubular trellis frame, horizontal back-link rear suspension — but the motorcycle evolves in 2022 with a colour TFT display and a further refined aesthetic presence in the sign of Sugomi design. A naked that seeks no compromise: upright position, wide handlebar, no fairing. For those who want to upgrade the exhaust of this generation, find the complete range in the exhausts for Kawasaki Z650 section.

In this category you will find the full exhaust systems we produce for the Kawasaki Z650 2021-2023. They replace the entire gas path from the engine outlet to the final muffler, headers included. The fitting kit is included and the mounting points are compatible with the original geometry. The under-engine position with lateral outlet requires care during installation: we recommend entrusting the work to a qualified mechanic for a precise and lasting result.

Replacing the entire original system on a naked with a dynamic vocation like the Z650 produces concrete and immediate effects. The weight reduction is felt both in the saddle and during manoeuvres: an already agile motorcycle becomes even more reactive in direction changes. Power delivery can become more fluid and direct, with a more responsive throttle that enhances the already lively character of the parallel-twin at mid revs. In some configurations the reduction in back pressure can contribute to freer engine breathing. The sonic character gains body and definition: more present, more coherent with the uncompromising aesthetics of the Z.

Every system is born from handcrafted manufacturing in Lombardy, in the province of Bergamo. To order, piece by piece, with internal quality control at every step. Direct from the manufacturer guarantees a direct relationship between those who build and those who receive, without intermediaries, with all the advantages that brings in terms of support and traceability.

As this is a full exhaust system on a motorcycle homologated to Euro 5, the original catalysed section is also replaced. The catalytic converter is available as an option from the drop-down menu on the product page. Choosing the catalysed version results in no delivery issues or warning lights: a short ECU adaptation period to the new exhaust is normal however, during which small variations in power delivery may appear that will resolve on their own. The Z650 Euro 5 ECU is capable of self-adapting to the new system without external intervention. Those who opt for the non-catalysed version should be aware that power delivery may not be optimal and that an ECU remap will likely be necessary to get the best out of the system. The non-catalysed version is reserved for track use or contexts where road compliance is not required, within the limits permitted by local regulations.

The dB killer is included as standard on all systems to ensure acoustic compliance. Its removal invalidates the homologation and is not a practice we recommend. For those who want to reduce the sound level further, the No-Noise version features an internally welded filter that lowers the decibels more decisively without significantly affecting the performance of the system. Where available, it is selectable from the drop-down menu on the product page.

Each system goes into production when the order is placed. Updated production times are always visible at checkout before confirming the purchase. The tracking code is sent automatically once the shipment leaves.
