Aggressive meets supernaked with this ideal blend of sporty performance and everyday versatility. Featuring next-level technology and a strong 649cc engine, the Z650 naked sportbike is a compact middleweight without equal.

Powerful & Smooth

A strong, torquey engine and lightweight chassis contribute to the Z650 motorcycle’s sporty performance and versatility.

Sporty Engine Performance

Raw power comes from a modern parallel-twin 649cc engine that packs strong torque and strong mid-range acceleration well suited for sport riding.

Assist & Slipper

An Assist and Slipper clutch provides a lighter feel at the lever and a back-torque limiting function that helps prevent rear-wheel hop during more aggressive downshifts.

Aggressive & Minimalist

Featuring Sugomi-inspired styling, the Z650 motorcycle boasts a strong appearance with a bold front face, minimalist bodywork and a sharp design.

Fierce, Predator-like Posture

The edgy, middleweight image is inspired by Sugomi, a design philosophy that integrates aggressive lines with minimalist bodywork to draw attention to functional beauty.

Seamless Fit

The sharp angles of the cowl, chin spoiler and meter cover were made to give the bike an aggressive presence while wide shrouds boast a muscular appearance. An LED headlamp adds a distinct high-tech note.

Sleek & Bold

The sharp Z pattern of the Z650 motorcycle’s taillight (brake light) deliver a bold statement every time it lights up.

Rigid & Lightweight

The exposed trellis frame helps deliver light handling and adds to the technical image of the Z650 motorcycle.


4.3-inch all-digital TFT (thin-film transistor) color instrumentation gives the cockpit a high-tech, high-grade appearance and visibility. The screen’s background color is selectable (black or white), and screen brightness adjusts automatically to suit available light. Display functions include: digital speedometer, digital bar-style tachometer, gear position indicator, shift lamp, fuel gauge, odometer, dual trip meters, current and average fuel consumption, remaining range, average speed, total time, coolant temperature, clock, battery voltage, Kawasaki service reminder, oil change reminder and the Kawasaki Economical Riding Indicator.

Rider and Machine Become One

Everything built in and around the lightweight chassis of the Z650 motorcycle is designed to become an extension of the rider.

Responsive & Balanced

The unique gull-arm style swingarm provides space for an under-engine exhaust for a lower center of gravity and improved handling. A horizontal back-link rear suspension offers an ideal balance of sport-riding performance and casual riding comfort. The telescopic front fork is a part of a balanced suspension package, tuned to provide progressive damping with a high level of feedback to the rider.

Fully Adjustable

For added comfort, both clutch and brake levers are 5-way adjustable to accommodate a variety of hand sizes.

Lightweight & Capable

The overall light weight of the Z650 motorcycle comes thanks to a lightweight trellis frame with a low center of gravity for light handling and confident low-speed maneuvering.*The Z650 is a significant 44.1 lbs. lighter than its European counterpart. This results in lighter more responsive handling for the Z650.

Extreme Grip

Dunlop Sportmax Roadsport 2 tires—made of high-performance rubber—boost handling and provide optimum grip.

Feel Connected

Ergonomics have a big influence on agile handling. The rider triangle places the rider “in” rather than “on top of” the bike for a feeling of confident connected handling.

Ride Confidently

Low seat height and tapered seat shape create easy foot placement at stops while the upright seating provides a commanding ride position, giving the rider heads-up visibility for a confident riding experience. Superior riding comfort extends to the passenger with thicker urethane and wide sides for increased padding and support.

Comfortable Positioning

A thoughtful footpeg position offers a relaxed knee bend for rider comfort.

Easy Maneuverability

A wide handlebar contributes to easy low-speed maneuvering and better leverage for higher-speed cornering.2020 model shown.
