Kawasaki introduced this Ninja-branded supersport in 1990 as a middleweight four-cylinder sportbike positioned below its larger-liter race replicas but above entry-level machines. The nameplate ran through the 2002 model year, making it one of the core Kawasaki sport motorcycles of the 1990s and early 2000s. Across its life, it evolved through several updates in styling, chassis design, and engine tuning while remaining focused on street and track performance. It also helped define Kawasaki’s ZX family before the later ZX-6R became the better-known long-running successor in the company’s supersport lineup. Enthusiasts remember it as an important transitional model: modern enough to wear the Ninja identity, yet still rooted in the era when 600-class sportbikes were rapidly developing into more specialized machines.
