Riders who want the soundtrack, smoothness, and precision of an inline‑four in a compact package will find the ZX‑4R ABS uniquely rewarding. It’s an ideal next step for experienced A2 or middleweight riders seeking a track‑capable machine that still excels on the street, and it makes an exciting addition for seasoned riders who appreciate high‑rev character in a manageable chassis.

This 2025 Ninja ZX-4RR KRT Edition ABS model suits experienced riders seeking a high‑revving, precision chassis in a compact package, newer track‑day riders moving up from smaller displacement machines, and enthusiasts who value sophisticated electronics and fully adjustable suspension in the 400cc class.
