This sport-touring nameplate debuted for the 2020 model year as Kawasaki’s refreshed successor to the earlier Ninja 1000, bringing the 1000-series inline-four platform under the then-new Ninja 1000SX badge. It was positioned as a long-distance sport bike rather than a full touring machine, aimed at riders who wanted supersport styling and performance with everyday comfort, integrated luggage capability, and modern rider aids.
For its initial run, the model shared its core 1,043cc inline-four architecture with the prior Ninja 1000 generation, but the 2020 launch marked a clear rebranding and update in equipment and presentation. The 2021 through 2024 model years continued the same basic nameplate, with year-to-year revisions focused on refinement, electronics, and trim details rather than a wholesale redesign. In Kawasaki’s lineup, it sat as the company’s liter-class sport-tourer: more comfortable and practical than a pure supersport, yet still styled and marketed with Ninja-family performance identity.
The nameplate’s continuous run ended after the 2024 model year, when Kawasaki introduced the larger-displacement Ninja 1100SX for 2025. That change effectively retired the 1000SX badge without any known separate earlier production period for this exact nameplate. Enthusiasts generally remember the model as the modern evolution of Kawasaki’s fast, versatile “do-everything” sport-tourer, bridging weekend back-road riding and real-world touring in a single package.
