# Kawasaki Z1000

The Kawasaki Z1000 (formally designated ZR1000) is a 1,000-class naked sport motorcycle built by Kawasaki since 2003, positioned at the top of Kawasaki's Z series. Its 2003 launch created what Kawasaki calls the Supernaked category, combining radical styling with the engine and chassis technology of a superbike rather than recycled components, and the model remained in production in some markets into the 2025 model year.

## Origins and the 2003 model

Kawasaki launched the Z1000 in 2003 to celebrate the 30th anniversary of the Z1, the company's landmark 1970s four-cylinder naked bike. The new bike carried a double-barreled exhaust, an aggressive headlight treatment, and 123 bhp from a ZX-9R engine bored out to 953 cc, yet reviewers found it tame enough for city riding<sup>[1](https://www.visordown.com/reviews/used-bike/buyers-guide-kawasaki-z1000)</sup>.

**Engine and chassis.** The 2003 bike took the carbureted ZX-9R engine and increased displacement to 953 cc with a 2.2 mm larger bore, adding fuel injection with 38 mm throttle bodies and sub-throttle valves. Cam timing and profile were changed to increase low and mid-range power, and the engine exhausted through four heat-treated stainless-steel mufflers with a golden color. The engine was mounted as a stressed member in a rigid diamond frame, with suspension consisting of a 41 mm inverted fork and a rear shock, both adjustable for preload and rebound. The 17-inch wheels came from the ZX-9R, and the front brake used 300 mm discs with the ZX-9R's four-piston calipers<sup>[8](https://www.motorcycledaily.com/2003/02/17february03kawasaki2003z1000/)</sup>.

At the time, naked bikes in the United States typically used older, already-paid-for components; MotorcycleDaily judged that the Z1000 moved the bar beyond Yamaha's FZ1, then the most high-tech bike in the category<sup>[8](https://www.motorcycledaily.com/2003/02/17february03kawasaki2003z1000/)</sup>. Kawasaki itself credits the 2003 model with establishing a new genre, the Supernaked, through its radical design and exceptional agility<sup>[2](https://global.kawasaki.com/en/corp/rd/magazine/174/pdf/n174en06.pdf)</sup>.

## Evolution through generations

Kawasaki freshened the bike in 2007 with slicker bodywork and more low-end torque, then completely redesigned it for 2010. The 2010 model gained a 90 cc larger engine with a 13 bhp gain, though it was 20 kg heavier than the 2003 bike, and ABS became standard<sup>[1](https://www.visordown.com/reviews/used-bike/buyers-guide-kawasaki-z1000)</sup>. Kawasaki's Japanese press release for the 2010 model describes a newly designed 1,043 cc liquid-cooled inline-four DOHC 16-valve engine, a new aluminum frame balancing light weight with high rigidity, short silencers, and a horizontally mounted rear suspension that placed mass close to the center of gravity, along with a full digital instrument panel that tilted to suit the rider's build<sup>[9](https://www.khi.co.jp/pressrelease/detail/c3091110-1.html)</sup>.

In 2011 Kawasaki added the Z1000SX, a separate sport-touring version with a fairing, tweaked suspension, and optional panniers and ABS<sup>[1](https://www.visordown.com/reviews/used-bike/buyers-guide-kawasaki-z1000)</sup>.

## The 2014 model

The 2014 Z1000, unveiled at the 2013 Milan Show, carried the sugomi design concept, a Japanese word Kawasaki translates as "awe-inspiring energy and intensity." Its design features a four-bulb LED headlamp positioned as low as possible, a bulging muscular fuel tank, and a sharply raised tail cowl, forming what Kawasaki describes as the image of a hunting predator<sup>[5](https://global.kawasaki.com/en/corp/newsroom/news/detail/?f=20131105_1830)</sup>.

**Engine.** [The 1](https://www.edgepedia.org/the-1),043 cc inline-four was reworked with a new intake camshaft, new airbox, new ECU, and taller velocity stacks, raising output to 142 horsepower at 10,000 rpm and 81.7 lb-ft of torque at 7,300 rpm<sup>[3](https://www.revzilla.com/common-tread/2014-kawasaki-z1000-abs-review)</sup>. Reviewers described a linear power band shared with the ZX-10R and ZX-6R sport bikes, pulling hard from as low as 2,000 rpm and coming alive around 7,500 rpm, with a soft rev limiter at 11,250 rpm that provides a brief overrev feeling rather than an abrupt cut<sup>[3](https://www.revzilla.com/common-tread/2014-kawasaki-z1000-abs-review)</sup>.

**Chassis and suspension.** The bike uses a twin-spar aluminum frame derived from the Ninja 1000, cast as a single unit with the swingarm pivot to eliminate welds; the engine is bolted to the frame in three places and rubber mounted at the rear of the upper crankcase<sup>[3](https://www.revzilla.com/common-tread/2014-kawasaki-z1000-abs-review)</sup>. Bike Review describes the frame as a cast five-piece aluminum twin-tube assembly with four engine mounts, three rigid and one rubber upper rear crankcase mount, plus a new three-piece aluminum die-cast subframe that is thinner and shorter than before, and six-spoke supersport-style wheels saving 1.5 kg over the previous model<sup>[10](https://bikereview.com.au/2014-kawasaki-z1000/)</sup>. The headline chassis change was the Showa Separate Function Fork – Big Piston (SFF-BP) inverted fork, in which compression and rebound damping are adjusted on one fork leg and spring preload on the other, making adjustments easier during a ride<sup>[3](https://www.revzilla.com/common-tread/2014-kawasaki-z1000-abs-review)</sup>. The instrument display switches from an LCD readout below 4,000 rpm to an LED sweep from 4,000 rpm to redline<sup>[11](https://ultimatemotorcycling.com/2013/12/05/2014-kawasaki-z1000-first-ride-review/)</sup>.

The 2014 Z1000 ABS carried a U.S. MSRP of $11,999, and MotorcycleDaily placed its chassis, suspension, and brakes near the top of the category<sup>[12](https://www.motorcycledaily.com/2014/04/2014-kawasaki-z1000-abs-md-ride-review/)</sup>.

## Standing among rivals

In a 2016 comparison test of five four-cylinder power nakeds by the German magazine MOTORRAD, the Z1000's 142 PS engine sat on a level with the 146 PS Suzuki GSX-S 1000, and both bikes were priced at exactly 12,195 euros. The Z1000 finished fifth of five with 637 of 1,000 points, behind the BMW S 1000 R (730), Suzuki GSX-S 1000 (694), Yamaha MT-10 (676), and Honda CB 1000 R (655). The testers praised its strong engine pull and braking power, second only to the BMW's, but criticized its firm chassis, lack of traction control, and the concentration its riding demanded; measured fuel consumption was 5.5 L/100 km on country roads, and service intervals were 6,000 km<sup>[13](https://www.motorradonline.de/naked-bike/bmw-s-1000-r-suzuki-gsx-s-1000-honda-cb-1000-r-kawasaki-z-1000-und-yamaha-mt-10-im-test-naked-bikes-mit-reihenvierzylinder/)</sup>.

## Later years

The 2017 Z1000 was updated for Euro 4 emissions with additional features and revised engine and chassis settings, with maximum torque of 111.0 N·m (11.3 kgf·m) at 7,300 rpm<sup>[6](https://www.teammotokawasakimoorooka.com.au/ssl/cms/files_cms/17504_2017_Z1000.pdf)</sup>. A Z1000 R Edition appeared in 2017<sup>[4](https://resources.kawasaki.eu/z50th/es/history/)</sup>. Kawasaki Australia still markets a 2025 Z1000 with the 1,043 cc In-Line Four engine, rigid aluminum twin-tube frame, radial-mount monobloc brake calipers, Horizontal Back-link rear suspension, and sugomi styling<sup>[7](https://kma.kawasaki-global.com/en-au/motorcycle/z/supernaked/z1000/2025-z1000)</sup>.
