Kawasaki Ninja ZX-7R

The Kawasaki Ninja ZX-7R is a 750 cc sport bike in the Ninja series that Kawasaki built from 1989 until 2003. It began as the ZX-7, a response to the race-oriented 750s of the late 1980s such as the Honda RC30 and Suzuki GSX-R750, after Kawasaki's older GPX 750R could not compete in the new Superbike World Championship. Outside the United States it was sold as the ZXR-750, and a homologation version for Superbike racing appeared from 1991 as the ZX-7R in the US and ZXR-750R elsewhere. In 1996 the ZXR name was dropped worldwide and the road bike became the ZX-7R, with the homologation machine renamed ZX-7RR. A liquid-cooled 749 cc inline-four sits in an aluminium twin-spar frame with Kawasaki's Uni-Trak rear suspension. The first year's engine was derived from the GPX 750R, and the 1991 models brought a new short-stroke engine and a slipper clutch. Racing versions won four AMA Superbike titles and one Superbike World Championship.
