Kawasaki ZX-7R (ZX-7RR)
The Kawasaki ZX-7R sports bike model appeared in 1996, replacing Kawasaki ZXR 750. The motorcycle was focused mainly on export to the countries of Europe and North America, and therefore practically not presented in Japan (only the ZX-7RR version was officially available in 1996).
Unlike its predecessor, the new Kawasaki ZX-7R has received several significant changes:
- Appearance. New plastic design, fox-eye headlights.
- New engine. It has become shorter-stroke, it gains momentum more easily.
- New brakes. Front 6-piston calipers.
- New carburettors. The "track" version of the ZX-7RR received oversized Keihin FVKD41 flat choke carburettors.
- Enlarged rear wheel. The size of the tire has increased - 180/55 ZR17 -> 190/50 ZR17.
The main modifications of the Kawasaki ZX-7R:
- Kawasaki ZX-7R - the usual "civilian" version.
- Kawasaki ZX-7RR - "track" version. It features a plug in place of the passenger seat, increased flat-throttle carburetors, Nissin brake calipers, additional suspension adjustments, a shorter gearbox, a heavier flywheel and a weight reduced by 3 kg. It was available from 1996 to 1997.
The Kawasaki ZX-7R was based on an in-line 4-cylinder liquid-cooled engine with a volume of about 750 cc, producing 122 hp. power and 78 Nm of torque. This characteristic is inherent in full-range motorcycle modifications (for example, models for the UK) and may vary downward depending on the market.
2003 was the last year of production of the Kawasaki ZX-7R, after which it was completely removed from the production line and did not receive further development. The "track" version of the Kawasaki ZX-7RR, despite the stated positioning, was often inferior in dynamics to the usual ZX-7R modification. This is because the large flat-choke carburetors made it difficult to optimally tune the engine and simply performed worse than with conventional vacuum carburetors.
