How the Z was born
The first Kawasaki Z900 was actually inspired by Honda at the Tokyo Motor Show in late 1968 as Honda unvieled new CB750 Four. A move that surprised the designers at Kawsaki as they were designing their very own 750cc bike! The CB750 Four offered never before seen power and a new type of engine, the Inline-four. With an OHC valve train, 67 hp, 200 km / h top speed, 4-into-4 exhaust system and front disc brakes. Kawasaki scrapped the new 750 idea and started work on a new bigger bike; code named T103. The 903cc engine size was the target thanks to market research done in the USA.
Thanks to the U-Turn approach Kawasaki did in dumping the 750cc idea for a 903cc one Honda did not have the slightest suspecsion as to what was taking shape in the Kawasaki garage. And what would emerge to be the most powerful and fastest production motorcycle with the best technical ingredients, the finest details and the most exciting design riders ever seen to date.
In early 1972 Kawasaki had a road worthy Z900 concept and begain testing in the USA. Two teams were set to ride 6000 miles each on public roads from Atlanta Georgia to Santa Ana California and back while also testing on the Talladega Speedway in Alabama. The Z bikes – some with Honda Emblems camouflaged tank – survived this distance without any damage.
Kawasaki debuts the new Z900 SuperFour to the press, who are so excited about it write an avalanche of media stories which get the public excited about seeing the world exclusive premiere of Kawasaki’s new Z900 at the 1972 IFMA in Cologne. When released for sale 2500 units are available and sold almost immediately as demand exceeds supply.
The Ultimate History of the Kawasaki Z
Since the debut of the 1972 Kawasaki Z1, motorcycles wearing the Z designation have revolutionised their respective eras and blasted a path to the future. Combining astonishing performance with advanced technologies and design, the Kawasaki Z bikes have had major impact on the history of high-performance motorcycles. This is the legend of the Kawasaki Z.
The legend was born in 1972 with the release of the model that started it all, the Kawasaki Z1. Featuring advanced Kawasaki technology, the Z1 completely redefined the world of high-performance motorcycling.
During development its code name was New York Steak. The letter Z was chosen because as the last letter of the alphabet it represented the most extreme, and the 1 stood for number one in the world.
The Z1 was the first mass-produced sports bike to feature a DOHC, 4-cylinder engine – technology found only on factory racing machines or limited production sports bikes. Displacing 903 cc, the Z1 was not only the fastest production motorcycle of its era, its reliability and durability were equally impressive.
The Z1 became a huge sales success in its target market of North America and also in Europe, and was equally successful on the race track.
Thus began the legend of the Z – a legend that continues to this day.

1972 Kawasaki Z – A Legend is Born
Featuring advanced Kawasaki technology, the Z1 completely redefined the world of high-performance motorcycling. During development its code name was New York Steak. The letter Z was chosen because as the last letter of the alphabet it represented the most extreme, and the 1 stood for number one in the world. The Z1 was the first mass-production sports bike to feature a DOHC, 4-cylinder engine – technology found only on factory racing machines or limited production sports bikes. Displacing 903 cc, the Z1 was not only the fastest production motorcycle of its era, its reliability and durability were equally impressive. Four mufflers accentuated the Z1’s slim, sexy and sleek design. The Z1 became a huge sales success in its target market of North America and also in Europe, and was equally successful on the racetrack. Thus began the legend of Z – a legend that continues to this day.
With the 900Z1 Superfour began the Z story. 1972 this model was presented at the IFMA motorcycle show in Cologne. Until then there had been no comparable motorcycle with so much capacity and so much power. The 900Z1 Superfour was a coveted cult object – to this day.
1972 Kawasaki presented for the first time a motorcycle with four-stroke engine from them. The four-cylinder in the 900 Z1 Super Four, a completely new development with two overhead Camshaft, 903 cc, and according to the manufacturer 82 SAE horsepower at 8500 rpm strong sat in terms of motor and driving performance with the production motorcycles new standards. It was to beat next year though. With amassive engine and a 4-in-4-exhaust system the Z1 was a huge hit. With outstanding performance to her name”. To date, the Kawasaki Z1 has successfully defended it’s aura among classics.

1974 Kawasaki Z400 (Europe)
The Z400 united many good features in an affordable motorcycle. The parallel twin engine was initially developed for the U.S. market as a robust and economical model for everyday life. It enjoyed but also extremely popular in Germany, and was built as Z440 and Z440 LTD as a soft chopper up in the eighties.
Kawasaki rose in 1974 in the Middle class with the four-stroke twin-cylinder Z400 designed for the U.S. market. The Z400 didn’t have the power the Z900 had but was still a great tourer. One of the attractions of the Z400 was cheap insurance due to the lower horsepower (27 or 33 hp; thus it was at the level of Japanese 250cc competition). Vibrations of parallel twins were tamed by the overhead cam and balance shaft and the Z400 became known as an environmental, durable and most comfortable motorcycle.

Two years after the introduction of the Z1, Kawasaki renamed the Z1 the Z900. 1976 also led to new paint and design changes. The four-cylinder is simply called now Z900 and no longer had a black engine but a silver one. The main technical difference was the dual disc in front which increased braking performance significantly with less hand force. Also the 1976 Z900 offered a more stable frame.

1977 Kawasaki Z1-R – Upscale Sports Bike with Avant-garde Design
During the 70’s, café racers with racing inspired designs were all the rage. The Z1-R, successor to the mighty Z1, was a special café racer version of the Z1000. The Z1-R was designed in the U.S., the main market for the Z-Series. It featured a stunning silver livery and unique styling never before seen on a large displacement sports bike. A slim fuel tank accentuated the massive black engine, and a bar-mounted bikini fairing advertised the R-model’s high performance. The Z1-R was also one of the first sports bikes to feature cast alloy wheels. Instead of the four mufflers of the Z1, the Z1-R used a 4-into-1 exhaust. The Z1-R heavily influenced the design of future Z-Series machines.
1977 Kawasaki Z1000, Z650 and Z200 (Europe)
With the Z1000, the magical capacity limit was cracked. At the same time, the model was also updated visually. Most notable here was the new 4-into-2 exhaust system. A great commercial success, the Z650, which brought the benefits and the look of the Z1000 in the middle class. Furthermore, Kawasaki thought of other target groups: With the Z200 a simply constructed cylinder came on the market, which was very cheap to obtain and operate.
Z1000: In 1977 Kawasaki enlarged the engine from 903cc to 1016cc by enlarging the bore four millimeters. This increased horsepower to 85hp @ 8000 rpm and increased torque from 73 Nm @ 7500 rpm to 81 Nm at 6500 rpm. With their new Z slogan “A bigger engine brings even more power, especially in lower speed range.” Kawasaski succeded in creating a motorcycle even better than the original for day-to-day power use. Other changes were a new 4 into 2 exhaust system, modified swing arm mount to improve riding stability and a disc brake.
Z200: At the 1976 IFMA Kawasaki presented Z200 as a simple, robust and economical entry level model for everyday use. With a single-cylinder engine with overhead cam delivering 17 bhp @ 8000 rpm the z200 was well received both in terms of performance and cost. The Kawasaki Z200 offered an economic alternative to the much more complex 125cc two-cylinder Japanese competitors of the day and offered electric start, front disc brake and a lightweight 145kg weight.

1978 Kawasaki Z1300 – The 6-Cylinder Monster that Shocked the World
The Z-Series machines established the popularity of the air-cooled In-line Four. However, the series continued to evolve. The Z1300 was powered by a revolutionary, liquid-cooled In-line Six displacing an incredible 1,268 cc, the largest of its time. Harnessing the engine’s massive power was a robust shaft drive. This flagship model boasted chassis and exterior components that were of the highest quality and performance. At 300 kg, the weight of this machine was equally impressive – in spite of this, test riders were seen wheelying the bike during its press launch. A road sport model built for fun, the Z1300 had so much power that it ran afoul of the West German horsepower regulations for motorcycles. The Z legend was now firmly established.

1982 Kawasaki Z1000R – Eddie Lawson Inspiration
In North America, the main market for big-bore sports bikes, superbike racing using highly modified production bikes was even more popular than World GP and attracted some of the world’s top riders. In 1981 Eddie Lawson won the championship for Kawasaki on a factory Z1000S. The Z1000R was built to commemorate that victory. The “Eddie Lawson Replica” was painted the same lime green as the Z1000S, and was a very popular model around the world. Like the Z1000S, the R model came with a Kerker 4-into-1 exhaust, a stepped seat and reservoir-equipped rear shocks.
1982 Kawasaki Z1000R – Eddie Lawson
THE LEGEND LIVES ON
After the highly acclaimed and hard-fought victory by Eddie Lawson in the AMA Superbike Championship in 1982 is the Kawasaki for the 1983 season is the Z 1000R – a flawless replica of the master street compliant machine.
Striking is the typical garish green Kawasaki paint with black and white decor strips, a small fairing (from GPZ1100B2) and the typical kink in the seat with a low driver’s seat cushion. Stunning visual appearance complete with rear Piggyback shocks and a smoky sound.
Changes – The Steering head angle changed from 62.5 to 61 degrees in order to provide more stability. The caster is enlarged by 15 millimeters. A revised braking system and a wider rear rim (2.50 instead of 2.15 in) complete the chassis improvements. The painted all black engine receives a modified cylinder head for more gas flow rate and an oil cooler from the GPZ1100, the operating temperature of the maintains a moderate level. A sticker on the tank, carrying Eddie Lawson signature reminiscent of winning a championship
Differences can be identified, especially in looks. Thus the tank, side covers and base color but remains the same. The sticker on the tank mentions Lawson’s second “AMA Champion Superbike Champion” in white Scripture. The instruments are sitting in a common housing. The swingarm falls from 10 millimeters longer and has slightly different reinforcements. In addition, it has once again modified the cylinder head slightly.
This model is the one that imported Kawasaki Germany.Japan only 500 units are available. While Lawson Replica in the U.S.A has 102 horseposer; Germany has 98 horsepower. This is largely due to the temperate, TUV-compliant four-into-two exhaust system and bespoke carburetor tuning.
From 4000 rpm the power comes on, 6500 rpm’s and above a huge surge of power. Combined with the easy switchable Five-speed transmission provide impressive performance. Top speed measures an incredible 223 km; not bad for an almost
faired motorcycle. Thus the Z1000R joins the ranks of the fastest Kawasaki Four-cylinder bikes, only the ’83-GPZ1100 has been quicker to date.
The Z1000R is sold for only one year in Germany due to the impending new four-cylinder generation Kawasaki GPZ with the sporting codes. The top model in the range, the GPZ900R with a liquid-cooled four-valve engine marks a new milestone in 1984
in the history of the brand. Other European countries and the U.S. have the Lawson for sale from 1983 to 1985 and displacement is enlarged to 1090 cc with 114 hp peak output. The era of the legendary air-cooled Kawasaki four-cylinder is coming to an end.

2003 Kawasaki Z1000 – The Z is Reborn as a Super-Naked
The 2003 Kawasaki Z1000 represented a return to the Z-models’ roots but with a modern engine and design flair. Rather than track performance and ultimate horsepower, the Z1000 delivered the traditional virtues of the Z-bikes: a sports bike that prioritised the rider “fun factor.” The Z1000’s 953 cc liquid-cooled 4-cylinder engine was based on the Ninja ZX-9R power plant rather than a previous Z model. Featuring a special cylinder head and fuel injection, the engine was tuned for more low- and mid-range torque. The four stylish mufflers were reminiscent of the original Z1, and the large-diameter, steel-tube diamond frame was fitted with top-shelf suspension components for responsive handling. Ultra-modern styling cues included an angular headlight and a sexy and compact tail cowl, giving the bike an aggressive look and creating a new genre: the Super-Naked was born.

2007 Kawasaki Z1000 – Shocking Style and More Refined Performance
This highly refined 2nd iteration Z1000 was based on the earlier Z1000 that had received rave reviews in Europe. Chassis upgrades included an all-new steel-tube diamond frame that incorporated a new aluminium sub-frame and mounted the engine as a stressed member, and a 25 mm longer wheelbase. Displacement remained unchanged at 953 cc, but improvements to the intake and exhaust systems resulted in more low- and mid-range torque for blazing acceleration at the cost of just 2hp. Other upgrades included radial-mount front brake calipers, and lightweight front and rear petal discs offering superior heat dissipation. The all-new exterior design included integrated radiator guards accentuating the Z1000’s concentrated, massive image. ABS was available as an option.

2010 Kawasaki Z1000 – Original Engine and Chassis to Create the Ultimate Z
To take the Super-Naked concept even further and made the 3rd iteration Z1000 even more fun to ride, Kawasaki’s engineers discarded the earlier method of using an existing superbike platform and instead started from scractch. They designed an all-new 1,043 cc engine tuned for hard-hitting low- and mid-range torque. Even the sound from the airbox and intake ducts during acceleration was used to enhance the ride feel. The chassis features a new aluminium twin-tube frame for responsive handling and light weight. Another interesting feature is the Horizontal Back-link rear suspension that contributes to mass centralisation and improved manoeuvrability. A low-profile front cowl and high tank are complemented by specially designed wheels and stylish front fork guards, giving the latest Z1000 a powerful, dynamic form.
The new Kawasaki Z1000 caused quite a stir. This unique naked bike design was a completely new approach adding on design cues from the Kawasaki’s past. The engine offers enormous power from the bottom end and the throaty intake sound makes the every rider addicted after a short time.

2014 Kawasaki Future Z
After writing this entire guide and studing the Kawasaki’s Z’s history (both good and bad points), I would like to see Kawasaki produce again a basic UJM (Universal Japanese Motorcycle) simular to the ZRX1200 or even Zypher/ZR7 in style, ergonomics and purpose. While the new 2nd and 3rd Generation Z750 and Z1000 motorcycle are impressive from a technological view point they are just not the “Z” classic style of motorcycle riders and customers want and unfortunately really are just “Z” models mostly due to the name and mostly naked inline-4 engine appearance. It would be nice to see Kawasaki again produce a line of classic bikes as they did with the new W800.
