2025 Kawasaki Ninja ZX-4R Base

2025 Kawasaki Ninja ZX-4R

Into a category filled with 400cc sport models, Kawasaki introduces a revolutionary supersport model. The Ninja ZX-4R mounts a 399cc in-line four engine with class-leading performance in a compact chassis with proportions essentially the same as the Ninja ZX-25R. On the track or on the street, experiencing the exhilaration of the Ninja ZX-4R’s heady power, intoxicating high-rpm wail, and its sharp, nimble handing will surely awaken the dormant supersport within you.

Features may include:

• All-New In-Line Four Engine

Powered by a high-performance, 399cc in-line four-cylinder engine with advanced racing-inspired technology, the Ninja ZX-4R supersport is a force to be reckoned with both on and off the track.

• Supersport handling, stopping power and ride character

A hallmark of the ZX series is razor-sharp handling with excellent feedback that inspires confidence, and the Ninja ZX-4R is no exception. This stems directly from Kawasaki’s WorldSBK racing efforts, and their work in developing the Ninja ZX-10R and Ninja ZX-6R. As a result, the Ninja ZX-4R offers a handling character similar to its siblings.

• High-Grade Package with High-Class Styling

Style meets substance with the Ninja ZX-4R’s high-class styling and high-grade package. Aggressive looks are complemented by premium features like TFT colour instrumentation providing clear information, integrated Riding Modes that link traction control and power modes for easy machine setup, and on the Ninja ZX-4RR a quick shifter for fast, simple gear changes.
