Kawasaki ZXR400 (ZX400H) 1989-1990

The sports motorcycle Kawasaki ZXR 400 appeared in 1989, replacing the model Kawasaki GPX400R, which by that time had "grown" into two models - Kawasaki ZXR400 and Kawasaki ZZ -R400. Specifically, the ZXR400 was modeled after the ZXR-4 racing model used in the TT-F3 series.


Main competitors:

At the time of its release, the Kawasaki ZXR 400 featured many advanced technologies found only in racing models. First, the model received a rigid aluminum frame. Secondly, the sporty, fully adjustable suspension (inverted fork). Thirdly, the ram-air system, which increases the maximum power. Fourth, powerful 4-piston brakes. Fifth, Kawasaki's proprietary technologies:

  • K-CAS - air duct system for cylinder head cooling.
  • K-BATL - torque limiting system (excludes locking of the rear wheel on a sharp downshift).
  • KIS-ARM - swingarm mechanism that increases the rigidity of the rear suspension and reduces its weight.


  • Kawasaki ZXR400 (ZX400H, ZX400L) - regular version.
  • Kawasaki ZXR400R (ZX400J, ZX400M) - "racing" version. Features a plug in the passenger seat, fully adjustable suspensions, different camshafts (taller cams) and flat throttle (FCR) carburetors (Keihin FVKD).

Another feature of the Kawasaki ZXR 400 is the fact that it was available not only in Japan, but also supplied to European countries. Export modifications produced up to 65 hp. power. Based on the Kawasaki ZXR 400 engine, the naked Kawasaki Xanthus 400 was created.

1999 was the last year of production of the model, after which it was finally removed from the Kawasaki production line. Nevertheless, the Kawasaki ZXR400 has gained great popularity not only in Japan, but also in some countries around the world. The most powerful in its class and more racing-like prototypes, the ZXR400 stands out clearly from similar models from other Japanese manufacturers.
