The Kawasaki Z1000 is a four-cylinder motorcycle in the streetfighter or standard style. It was first introduced in 1977 as the Z1000A1 model - and superceded the previous 903cc capacity z900's.

History

Kawasaki introduced the Z1 (900) motorcycle in 1972 as the first of the Kawasaki Z series. Four years later they introduced the Kz900. The original Z1 was the first series of Japanese motorcycles with the combination of four cylinders, dual overhead cams and 903 cc (55.1 cu in).

In 1977 a Z1 ridden by Reg Pridmore became the first Japanese bike to win an AMA Superbike national when it took the victory at Pocono Raceway. Pridmore went on to win both the 1977 and 1978 US Superbike Championships on Kawasaki Z1s. The Z1000A1 model of 1977 continued into 1978 as the Z1000A2 model, with styling changes only. During 1978, Kawasaki made the bold decision to release a factory 'cafe-racer' style of model, to compete head-on with the BMW R90S. The result was the Z1R - the first Kawasaki model to feature squared-off body styling with tank, sidecovers and rear tail piece all styled in a very square manner compared to earlier models that used a flowing, rounded style to the bodywork.

The Z1R used the older Z1000 motor, which was a bored-out 900 motor.

For the 1979 and 1980 model years, the Z1000 'Mk II' (mark two) version was added with black engine, general restyling including body and paintwork and a shaft-drive version was available, designated Z1000ST. There was also an update Z1R model, called the Z1R MkII. The upgrades to the MkII model were many and included thicker engine covers to reduce noise, upgraded clutch, main bearing journals that used 2mm-wider bearings for improved crank longevity and a 16/32 ratio for the cam chain drive (earlier models used 15/30). The Z1000 models continued until the early 80's. The last Z1000 that was still based on the original Z1 of 1972 (with a kickstarter and peanut-roller style cam chain) was the 1980 Z1000H model. This model was a limited-edition release with only 1000 units made for the global market. The Z1000H was the first mass-produced fuel injected motorcycle released on the world market.The last model Z1000 air-cooled model was the 1981 Z1000J model - which was based on the GPz1100 B1 model of the same year. The Z1000J model was not fitted with a kickstarter and used a hy-vo style cam chain. It was built with a capacity of 998cc so that it would be eligible for US production racing, which had a limit of 1000cc. The earlier Z1000 motors were not eligible as they had a capacity of 1015cc.

In 2003 Kawasaki introduced a completely revamped 30 year anniversary edition of the Z1000. It used a modified engine from the Kawasaki ZX-9R, and was bored out by 2.2 mm resulting in bigger displacement, more low-RPM torque, and only a slight power loss of 4 bhp from the original ZX9.[citation needed] In 2004, Kawasaki released the Z1000's smaller brother, the Z750. In 2007, Kawasaki released a new Z1000. The Z-series since the 1970s until today are also known as the "Z", "Zed", and "Z1k".

In October 2009, Kawasaki unveiled the 2010 Z1000. It had a new aluminum frame, digital instrument panel, bodywork, and engine. Bore and stroke are 77 x 56 mm, 1 mm more than the ZX-10R’s 76 x 55 mm displacing 1,043 cc. That is up from the previous model's 953 cc. Compression ratio is 11.8:1, and fuel injection is handled by a bank of 38 mm Keihin throttle bodies.[1]

2003–2006 Models

Stylistically, the 2003 Z1000 was a departure from other naked sportbikes of the time. The Z1000 used the same tail section that was being used on the 2003 ZX6R 636 cc sport bike.

It has a 4-2-4 exhaust system. The Z1000 uses a backbone frame that supports the engine as a stressed member. Engine mounts can be removed to ease access for maintenance. Compression damping is done on one fork leg, rebound damping on the other. This technology is from dirt bikes, and is rare on street motorcycles. The Nissin brakes have four piston calipers.

2007–2009 Models

2007 Kawasaki Z1000

In 2007 Kawasaki released an updated version of the Z1000. The bike features a detuned version of the ZX-9R engine. This detuning, in addition to the design of the exhaust, provides less top end compared to the super-sport ZX-9R engine, but more low to mid rpm range.[citation needed]

2010–2013 Models

The Z1000 was redesigned for 2010. Along with the customary styling update came a slightly larger capacity engine. The motorcycle was officially marketed as the "Z1000 ABS" as ABS came fitted as standard.[2]

In 2013 Kawasaki broke with the 3 year update cycle and choose to release a "special edition", alongside the standard edition, to mark the 40th anniversary of the Z brand.[3] The differences between the models were purely aesthetic.

2014–2016 Models

The Z1000 was restyled and updated for 2014 making slightly more power and front brake caliper are 4 piston monoblock. Also a big piston Showa separate function fork along with lighter wheels and a slightly larger gas tank.[4][5]
