Z900RS Yellow Ball Edition Features

Iconic “Yellow Ball” Styling

Drawing from Kawasaki’s collection of legendary machines, the Z900RS Yellow Ball styling is reminiscent of the iconic “Yellow Ball,” a black and yellow version of the orange and brown “Fireball” paint of the original Z1.

Lights

Z1-Inspired Tail Cowl and LED Taillight. The flowing design of the rear cowl was inspired by the duck-bill tail cowl of the Z1. Round LED Headlamp. A blend of retro and modern designs, the large ø170 mm LED headlamp casts a bright, white light for great nighttime visibility.

Engine and Exhaust

Simple, Uncluttered Engine Design. With a naked bike, the engine is an important styling element, and with its simple, uncluttered design the engine adds to the Z900RS’ presence. Carefully Considered Exhaust Shape, Construction, Material and Finish When designing the exhaust system over 20 variations were considered before arriving at the final design, one that emphasizes the presence of the In-Line Four engine.

Lightweight Trellis Frame

Complementing a light overall weight (noticeable as soon as the bike is lifted off its side-stand), frame rigidity and chassis geometry tuning were selected to deliver light, natural handling. Like the engine, the chassis responds to rider input predictably, going where the rider wants it to without resistance. In keeping with its retro sport model character, the Z900RS’ stance is less forward-leaning than the Z900.

Radial-pump

Radial-pump front brake master cylinder also contributes to the superb control and feel offered by the calipers. For added braking reassurance, ABS is a standard feature on the Z900RS.

Timeless Styling

With a seamless blend of Z1-inspired styling elements and modern craftsmanship – from the iconic teardrop fuel tank to the innovative oval LED taillight – the Z900RS offers timeless good looks with an exquisite attention to detail and superb fit-and-finish that results in a very high-quality appearance.

Assist & Slipper Clutch

Race-inspired clutch technology offers both a much lighter feel at the lever, as well as a back-torque limiting function that helps prevent rear-wheel hop when downshifting.

Ergo-Fit

To accommodate every rider Kawasaki offers an ERGO-FIT accessory seat which reduces the seat height 35mm. Drag the slider to see the difference. The stylish two-tone seats use different materials for the top and sides to create a high-quality design. Double-stitching adds to the high-quality image.

Radial-Mount Front Brakes

At the front, ø300 mm brake discs (effective diameter: ø267 mm) are gripped by opposed 4-piston radial-mount monobloc calipers. The monobloc front brake calipers offer a firm initial touch, the level of brake force is very easy to control, and overall brake performance is superb.The machined monobloc calipers feature an alumite coating and are laser-etched with a Kawasaki logo, adding to the bike’s high-quality sporty looks.

KTRC (Kawasaki Traction Control)

Contributing to rider reassurance, the Z900RS is equipped with advanced Kawasaki rider support technology. KTRC features two modes that cover a wide range of riding conditions, offering either enhanced sport riding performance or the peace of mind to negotiate slippery surfaces with confidence. Riders may also elect to turn the system off.

In-Line Four Engine

Like the Z1, the Z900RS features a 948cc-class In-Line Four – an engine configuration that inherently offers a great balance of power and manageability. Tuning focuses on the low-mid range. Revs build in a measured, but very determined manner, giving the rider a sense of connectedness between the throttle and rear wheel.

Spoke-Style & Teardrop

Spoke-Style Cast Wheels. Original cast wheels feature flat spokes designed to look like classic wire-spoked wheels. Iconic Teardrop Tank. The centrepiece of the Z900RS’ design, the beautiful teardrop fuel tank is reminiscent of the Z1.

Dual-Dial Instrumentation with Multi-Function LCD

Analogue-style speedometer and tachometer dials are complemented by a multifunctional LCD screen, balancing retro-style looks with modern functionality. The LCD has an easy-to-read, negative (white letters on a black background) display. Bullet-shaped dial cases are a fitting touch for a retro sport model, while a spindle finish on the dial faces adds to their high-quality design.

Kawasaki’s First Tuned Exhaust Note

While Kawasaki In-Line Four engines are historically renowned for their great-sounding exhausts, this the first time that Kawasaki has conducted sound research to craft a model’s ideal exhaust note. Designed to elicit rider response, the sound tuning focused on the engine’s initial roar to life, idling and low-speed riding where the rider is best able to enjoy the exhaust’s deep rumble.
