Exhausts Kawasaki Z650 2017-2020

The name Z650 is not new: it was already carried by a 1976 motorcycle, one of the first Kawasaki mid-displacement four-cylinders that redefined the category at the time. When in 2017 Kawasaki decides to drop the ER-6n designation and adopt the Z name, the message is clear: this naked joins the Z family, the Sugomi family, the family of aggressively styled, sharp-edged motorcycles that begins with the Z1000. The steel tubular trellis frame is completely new — inspired by the Ninja H2, it weighs just 15 kg — and brings the Z650 to 188 kg ready to ride, nearly 20 less than the ER-6n it replaces. The 649cc parallel-twin is recalibrated for Euro 4 homologation with particular attention to mid-rev delivery: that is where this motorcycle gives its best, with a full and manageable torque that lends itself equally to everyday riding and mixed-road routes. 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 2017-2020. 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.

On a naked with an already contained weight like the Z650 2017-2020, further lightening the under-engine area with a full exhaust system has a direct and perceptible effect. The motorcycle becomes even more reactive in direction changes, easier to manoeuvre, more immediate in its responses. The parallel-twin's power delivery can become more responsive and fluid, with a more direct throttle response that enhances the characteristic mid-rev torque. In some configurations the reduction in back pressure can favour freer engine breathing. The sonic character gains body and presence: more defined, more in keeping with the Sugomi design that visually characterises this generation.

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 4, 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. The Z650 Euro 4 ECU is capable of self-adapting to the new system without external intervention: in the first rides small variations in power delivery may appear, which will resolve on their own over the first kilometres. 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.
