1990

First Ram Air System Hits the Market
To boost engine output, Kawasaki mounts an air intake duct at the front of the fairing to force-feed air directly to the airbox. This is the industry’s first application of a “Ram Air System” on a production motorcycle and gives the Ninja ZX-11 an unbelievable maximum power. This “monster bike” also features the first speedometer with a 320 km/h dial. The combination of huge horsepower and sophisticated aerodynamics make it the world’s undisputed “King of Speed” for the next six years. This model gives birth to the “flagship” category.

 

1993

Technology Upgrades for the Flagship
To ensure its position as the world’s dominant production motorcycle, the Ninja ZX-11 gets a major model change. Upgrades include Dual Ram Air Induction, a lighter aluminium perimeter frame and larger-diameter front disc brakes. The new model continues its predecessor’s reign as the world’s fastest production motorcycle.

 

1994

Big-Bore Supersport
Featuring an engine heavily influenced by the ZXR750, but with more displacement, twin Ram Air intake and an aluminium frame, the radically new Ninja ZX-9R offers an unparalleled balance of size, power and rider-responsive handling. Taking high performance to an entirely new level, this 900cc supersport model sets the standards for others to follow.

 

1996

Race Developed Performance
Replacing the championship-winning Ninja ZX-7/7R (ZXR750/R), the new Ninja ZX-7R and limited edition 7RR feature shorter-stroke engines and new aluminium perimeter frames. A limited-production racing homologation model, compared to the 7R the 7RR features variable rake, an adjustable swingarm pivot, a shorter wheelbase, and a racing seat. Winning races around the world, it firmly establishes the Ninja’s reputation for high performance.

 

1998

Uncompromising Performance
The all-new Ninja ZX-9R shatters the status quo. Smaller, lighter and more powerful, it features a compact new engine with Kawasaki Throttle Responsive Ignition Control (K-TRIC), “stick-type” plug-mounted ignition coils, magnesium engine covers and a titanium muffler. A shorter, lighter chassis uses the engine as a stressed member allowing the twin down tubes to be eliminated for high compactness.
