2019 MODELINFORMATION MODEL NAME Z900RS / Z900RS CAFE

Kawasaki

Classic Design + Modern Technology = Z900RS

Inheriting the elegant styling of the original 1972 Z1, the new

Z900RS immediately identifies itself as "Kawasaki" to an amazing degree. At the same time, the new model incorporates the latest technological advancements,

enhancing retro style with cutting-edge performance. However, this new model is engineered to make a strong statement about the Kawasaki brand through a revised set of

priorities. While outright speed is an important value, throughout the final product we have focused our skills on overall performance, to honour our unique brand history, heritage, and standards of quality.

Augmenting the Z900RS is the Z900RS CAFE, which features

a cafe-racer style cowl and seat, drop handlebars, brushed silencer finish and unique colour and graphics styles.

1. Liquid-Cooled, 4-Stroke, DOHC, 16-Valve Engine

The original Z1 guaranteed that premier performance would thereafter be packaged in an inline four-cylinder package, a design that became the pride of the Kawasaki brand. Designer Gyoichi "Ben" lnamura* and his team created an engine packing 15 more peak horsepower than the top Norton of its day. It also delivered a broad, highly tractable powerband.

*Gyoichi lnamura developed the first four cylinder DOHC engine for

Kawasaki and is the forefather of Z-series engines.

So does the new Z900RS. With peak horsepower of 82kW (111PS) at 8,500min-1, the new Z has nearly 50% more power to work with, and it's applied to a low to mid RPM delivery that will be a revelation to riders of all ages. It's powerful and smooth from urban highways to winding roads. This motorcycle is not just for expert big-bike riders. It's designed to provide an inspiring riding experience for nearly everyone, with an incredibly broad torque curve, peaking at 98.5N • m(10.0kgf·m, 72.6ft ·lb) at 6,500 RPM.

The specifications mentioned here apply to and have been achieved by production

models under standard operating conditions. We intend only to give a fair description of

the vehicle and its performance capabilities but these specifications may not apply to

every machine supplied for sale.


The liquid-cooled, DOHC, 16-valve 948 cm3 inline four unit is based

on that of the Z900, but for the Z900RS Kawasaki engineers wanted

to create a completely different engine character. While the Z900

engine has a sharp, quick-revving nature that encourages high-RPM

operation, the Z900RS was tuned for the low-mid range, delivering

strong torque that enhances the experience or performance for

riders of all skill levels.

The crowning touch is a soul-stirring exhaust note, achieved through

a sensuality evaluation process for the first time in Kawasaki's

history. The ultimate riding experience now comes with seemingly

endless power and truly captivating sound. Kawasaki's experience

with sound tuning started with the 2014 through 2016 Z1000 and

2017 Z900, leveraging this know-how when designing the Z900RS.

* Cylinder HeadAlthough liquid-cooled, the engine features stylish fins that conjure

up an air-cooled image in a nod to the Z1 heritage. The sides of the

head feature a partially buffed finish that is a classy retro touch.

* Camshaft

Relatively shorter angle of cam profiles delivers stronger power at

low-mid RPM as well as the smooth power delivery typical of

four-cylinder engines. Cam profiles with shorter intake (270o>>248o)

and exhaust (256o>>244o) duration focus engine performance on

the low-mid RPM range. A strong and smooth response makes the

engine very manageable. Complementing the shorter-duration cam

profiles, the compression pressure was lowered to 10.8:1 (compared

to 11.8:1 on the Z900).

5

* Combustion Chambers

The chamber shape and combustion ratio optimally exploits the Z's

cam characteristics, for power that feels super-smooth and easy to

modulate. The pre-chamber enhances environmental performance,

enables a smaller silencer design and contributes to the carefully

crafted exhaust note.

* PistonsThe light and rigid pistons were crafted with a unique casting

process similar to forging that removes unnecessary material and

creates hollows to achieve the ideal thickness. AV-groove on the

piston's 2nd land helps control pressure between the piston rings by

idealising the gas volume. This helps to prevent top ring fluttering

and maintain a better gas seal, reducing blow-by gas and oil

consumption.

* CrankshaftThis has an approximately 12% greater flywheel mass than the

Z900, adding to the feeling of strong, tractable power at low-mid

RPM - all with the depth of horsepower typical of four-cylinder

engines. A secondary balancer driven off a gear on the sixth web of

the crankshaft eliminates excess vibration.

* Intake Funnels

The length was adjusted to enhance the low-mid power

characteristics that only a four-cylinder engine can deliver.


* Electronic Control Unit (ECU)

All settings are programmed to achieve the strongest possible

performance over the entire rev range, enhancing the super-smooth

power delivery.

* Drive Train

We put a clear emphasis on easy urban manoeuvrability as well as

long-distance comfort by making first gear short, and sixth gear

long. Thus starting from every stop is effortless, and velvety power

is ensured at highway speeds.

* Kawasaki Traction Control (KTRC)

The Z900RS' KTRC system offers two performance modes-one

for optimum sport riding performance, and one for optimum stability

in slippery conditions by preventing wheel slip. In Mode 1, highlysophisticated programming allows a degree of slip to maximise

acceleration. Mode 2 uses the same logic and control as in Mode 1

during normal operation. When excessive rear wheel spin is

detected, however, Mode 2 switches to three-way control, governing

ignition timing, fuel delivery, and airflow, reducing engine output so

the rear wheel regains grip. By default, the system is always on

when the engine is started. To ride with the system off, riders must

consciously turn it off using the mode button on the left grip.

6

* Assist & Slipper Clutch

The assist and slipper cams offer two

functions not available on a standard

clutch. At normal RPMs, the assist cam

functions pull the clutch hub and

operating plate together to compress the

clutch plates, reducing the clutch spring

load and lightening the clutch lever pull.

Under heavy engine braking from quick

or accidental downshifts, the slipper cam

forces the clutch hub and operating plate apart, relieving pressure

on the clutch plates to reduce back-torque and prevent rear tyre

hopping and skidding.


2. Exhaust & Sound Tuning

Achieving optimal power and sound is a highly complex balancing act. We engaged in a long process of experiments, with various

parameters, prototypes, and sophisticated analysis to achieve a new

level of performance on both counts. This unprecedented development process included:

1. A series of alterations of the length and diameter of exhaust pipes

and their shapes.2. Multiple alterations of the exhaust chamber shape and position.

3. Multiple experiments with every other detail - including even the

length as well as the density of the glass wool.

7

As a result, we are confident that we are now offering the best

exhaust system on the market. The new Z generates a low, thick exhaust note that perfectly matches its retro image. While complying

with every applicable regulation, this exhaust delivers volume and

tone that virtually shout power. It also clears Euro 4 regulations

through catalysers in the collector pipe that clean the emissions.

* Exhaust Pipes

A triple-buff process ensures a classy, premium look. Double-wall

stainless pipes are elaborately bent to achieve the precisely

engineered system, which forgoes a connecting pipe to achieve

aesthetics that best match the unique retro look. Thus the new Z

delivers the highest-quality sound, performance, and style. Note that

the Z900RS CAFE silencer features a hairline finish instead of buff

treatment.

* Chamber

A painstakingly crafted stainless-steel exhaust chamber enables

compact silencer design, and enhances the breakthrough retro

exhaust note. Its positioning ensures efficient mass-centralisation.

* Silencer

The short megaphone silencer was achieved by straightening the

inner structure. Many experiments were conducted to determine the

optimal density and other features of the glass wool. Thisstainless-steel silencer puts a strong emphasis on both style and

exhaust sound that are unique to the retro category. The rigorous

exhaust development process has yielded a system that is truly the

best match for the Z900RS.


3. Frame & Bodywork

Designed with easy manoeuvrability as the highest priority, the

teardrop fuel tank was placed at the optimal position in ergonomic

terms, and the 35° steering angle ensures a package with a tight

turning radius. The unique look is achieved by crafting every

component with the latest technology, while applying retro visual

cues throughout, providing a look and feel that you can enjoy whether relaxed or racing.

* Trellis Frame

The frame was completely redesigned to accommodate the slimteardrop fuel tank and offer retro handling optimal for enjoyable

riding at a more measured pace. A relatively large upper/under

bracket steering offset helps achieve the natural yet agile steering

control suitable for a retro-style model. In addition, the narrow

spacing of twin mainframe tubes under the fuel tank delivers both

suitable stiffness and a slim body. This

new trellis-style frame was designed with

an emphasis on balance, from size to

overall form.

8

* Rear Suspension

* Front Suspension

Top performance is achieved with an

adjustable 41mm inverted fork.

Easy-to-adjust settings match

everything from city streets to winding

country roads, providing comfort and

handling to accommodate rider

preferences and riding styles.

To ensure ideal mass

centralisation, optimal exhaust

tuning, and superior handling, we

adopted a single-shock and

Horizontal Back-Link rear

suspension. With this design, the

exhaust chamber is nearly

invisible, adding to the simple,

beautiful profile. This design

contributes to the natural and relaxed handling typical of a retro bike.

It also ensures that the suspension is far enough from the exhaust

that operation is not affected by heat.


* Front and Rear Brakes

The 300mm front discs employ radial-mount calipers, and a

radial-pump master cylinder with a 19mm-diameter piston highly

reminiscent of the Z1. This braking system is designed with an

emphasis on control rather than pure stopping power, ensuring

maximum possible performance with highly linear braking feel. The

machined monobloc calipers feature an alumite coating and are

laser-etched with a Kawasaki logo, adding to the bike's high-quality

sporty look. A radial-pump front brake master cylinder contributes

to the superb control and feel offered by the calipers. A newlydesigned 250mm rear disc employs a single-piston caliper,

ensuring highly predictable performance. Sintered brake pads frontand rear contribute to the control and feel. The compact, light

Nissin motorcycle ABS unit provides added reassurance inemergency situations.

9

* Wheels & Tyres

The new cast wheels are the

result of Kawasaki's advanced

analytic technology, achieving

the optimal balance between

appearance and weight

reduction. This unique cast

design offers a wire spoke-like

appearance that highlights

differences in spoke style for an

especially classy look. The wheels are fitted with Dunlop GPR 300

tyres, made with a compound designed exclusively for the Z900RS,

which ensure superior handling and suitable retro style. A low

unsprung weight from savings with the swingarm and wheels

contributes greatly to the light, natural handling.


4. Quality Components and Surface Finishes

To help achieve the most impressive "Timeless Z" model concept,

we put extra emphasis on quality that offers higher value regardless

of era. In order to highlight the retro feel of the Z1, classic curves are

paired with the latest components in a refined design. Rounded

design elements are applied from front to back, and further accented

with special paint for a sharp, classy look.

* Headlamp

A blend of retro and modern designs,

the large cp170mm LED headlamp

casts a bright, white light for great

night-time visibility. It features six

chambers (four for low-beam, two for

high-beam). Position lamps in the

high-beam chambers ensure the

whole lamp appears lit, like aretro-style bulb headlamp. Details like a convex lens and chromed

headlamp ring add to the high-quality, retro design.

* Turn Signals

The cutting-edge technology

continues with LED lamps in the

turn signals (US models use bulbturn signals).

11

* Rearview Mirrors

New rearview mirrors have been

developed, based on the design used

for the Z1. The mirrors are

engineered to provide a clear rear

view at speed while adding retro

style. The Z900RS CAFE features

the same mirrors, but uses shorterstays in keeping with its styling.

* Front Fender

The three-piece front fender, withour proprietary die-cast aluminium

support, delivers a retro flavor in a

novel way. The aluminium support is

crafted as thin as 1.7mm, cuttingweight to a minimum.


* Instrument Panel

The oval instrument panel consists of

analogue pointers and 3-D dial

faces, complemented by modern

LCD displays. The panel features a

gear position indicator, fuel level

meter, ambient temperature indicator,

current and average fuel

consumption indicator, range

indicator, clock, odometer, and tripmeter.

* Handlebars

The "fat" bar comes in

chrome and black, and is

positioned for an upright

riding position that's

comfortable for trips of any

length. Relative to the

Z900, the handle grips are

65mm higher and 35mm farther back (closer to the rider). A wide

350 steering angle enhances low-speed manoeuvring. The

Z900RS CAFE features a drop handlebar that complements the

cafe-racer design.

12

* Fuel Tank

A 17-litre tank extends below the

seat , resulting in a slim design. The

tank volume to enable a substantial

cruising range, as the Z900RS

delivers excellent fuel economy on

long-distance rides. The classic

teardrop shape plays an important

role in the ergonomically natural

riding position while enhancing the authentic retro appearance. Side

covers were designed to flow naturally from the tank. Emblems on

the side covers contribute to the retro styling. The stylish fuel tank

cap complements the elegant lines of the tank.

* Taillight

The oval-shaped taillight features a

single large LED bulb in the centre

to complete a true Z1 look. It lights

as a solid surface, while the

reflector around the periphery

diffuses vivid light.


* Seat

The double-stitched, two-tone seatcan be had in two styles (low or

high). The seat is stepped and offersa wide seating area for good ridecomfort for the rider and passenger.The seat is slimmer at the front to

improve rider reach to the ground.The low seat height and the bike'sslim overall design make it easy to keep both feet firmly on theground when stopped. The seat can be removed without tools,offering easy access to the battery, fuse box and tool kit. TheZ900RS CAFE features its own cafe-racer style seat with a more

pronounced step. An accessory ERGO-FIT low seat reduces the

seat height 35mm (depending on the market, a low seat is standard).

13


* Shift Lever and Brake Pedal

The forged aluminium shift lever and brake pedal are a nod to the

Z900RS' functional beauty.

* Engine Covers and Knee Position

The die-cast aluminum engine covers are painted in black. Pressed aluminium knee grip covers are surface-treated to offer a classy retro look and long-lasting finish. On the Z900RS CAFE, a black alumite coating contributes to the cafe-racer design. The narrow frame and engine create a narrow overall package so riders can keep their knees and feet close together.

* Footpegs

The footpegs are 20mm lower and 20mm farther forward than on the Z900, contributing to an even more relaxed riding position. Rider footpegs feature rubber pads to reduce vibration transmitted through the feet.

* Luggage Hooks

Convenient hooks on the tail cowl and rear flap were designed to stick out to prevent bungee nets and tie-down ropes from damaging the elegant bodywork.

Authentic Accessories

Genuine Kawasaki accessories allow riders to customise the Z900RS' timeless looks or offer added comfort or convenience for

long rides (availability will vary by market). Accessories include an ERGO-FIT low-seat offering an easier reach to the ground. Like

the ERGO-FIT high seat, it features two-tone leather and double-stitching. Other accessories include heated grips, tank

emblem, tank pad, meter indicator cover, front fork caps, radiator screen, front axle sliders, frame sliders, oil filler cap, centre stand,

a side grip to help manoeuvre the bike onto the centre stand, and a grab bar.
