KEY FEATURES
Powerful Engine
Transmission
Smooth-shifting six-speed transmission complements the sporty street performance, offering a gear for every situation. The clutch engages smoothly and disengages cleanly, making it easy to operate for new riders and optimising clutch feel for on-road performance.
All-digital Instrumentation
All-digital instrument panel gives the cockpit a modern, sporty look.
Brakes/wheels/tyres
Front and rear disc brakes offer impressive stopping performance. Dualpiston calipers grip a ø290 mm disc up front, and a ø220 mm disc at the rear. Petal disc design adds to the sporty Kawasaki looks.
ERGO-FIT Low Seat
ERGO-FIT seats enable riders to select seats that optimise their fit on the bike. For the Z125, an ERGO-FIT low seat (-25 mm) is available. (Patterns on the seat material are unique to each machine.)
Sharp Taillight Design
Sharp taillight design enhances the sporty look of the rear.
Independent Sport ABS
Standard equipment ABS contributes to rider reassurance. The highspec system was designed specially for motorcycles and features a very compact ABS unit. Independent activation maximises sporty control.
Full-size Chassis
The Z125 features a full-size chassis. With a slim, compact trellis frame, sporty suspension and lightweight 17” wheels, the light, nimble handling they offer is ideal for new riders to become familiar with operating a full-size motorcycle.
Slim, compact trellis frame
Trellis frame enables a slim, compact package that is easy to manage, and makes it easy to reach the ground with your feet.Supernaked Ergonomics
The Z125 light, nimble handling character together with an upright riding position and wide handlebar put the rider in the ideal position for active control, facilitating dynamic, sporty riding that enables the Z125 rider to deftly navigate urban traffic.
Uni Trak Rear Suspension
Uni Trak rear suspension provides great road holding ability and bump absorption, contributing to the bike’s sporty handling. The shock linkage decreases leverage on the shock as the suspension is compressed: small bumps are damped very lightly while big bumps receive lots of damping. The shock has a 5 stroke of 60 mm, helping to ensure the balance of lightweight handling and a composed character. 5-way rear preload adjustability allows riders to adjust the rear ride height, as well as set up the bike to accommodate a passenger or luggage.
Sporty Suspension
ø37 mm telescopic fork contributes to both light, nimble handling as well as a generally composed riding character. Kawasaki’s original linkage-equipped Uni Trak rear suspension delivers a smooth ride over a wide range of road conditions.
Z Supernaked Styling
Like its larger brothers in the Z Series, the Z125’s aggressive styling hints at its sporty potential. A dynamic design created by its slim, hourglass figure is complemented by extremely lightweight looks care of sharp, close-fit bodywork and an original trellis frame.
