Kawasaki ZR-7

The Kawasaki ZR -7 is a motorcycle in the category naked bike from the Japanese manufacturer Kawasaki, which was sold from 1999 to 2004. Competing models were the Suzuki GSF 600, Yamaha Fazer and the Honda CB 600 F Hornet. Kawasaki remained faithful in the motorcycle of his legendary line of four-cylinder, air-cooled engines, with the traditional 750 cc. Through their extra engine capacity offers the ZR -7, compared to the competition, today especially through its enormous performance. The concept worked. After her introduction, she became the best-selling motorcycle from Kawasaki in Germany soon.

However, the introduction of the Euro 3 standard strict ultimately led in 2003 to stop production of the ZR- seventh A renovation would have been possible only with considerable effort and was not in any healthy relationship to the already sharp decline in sales. Thus, the ZR- 7 of its successor, the Kawasaki Z 750 was replaced.

Nevertheless, it has a large fan base, who appreciate their extremely loyal and reliable companion in today's times.

Predecessor

The ZR -7 is one of totally redesigned bike that has only accepted the engine from the predecessor Zephyr 750. However, this was clearly technically obsolete.

Development

Changes to the engine compared to the Zephyr 750 included the introduction of the K- TRIC ( Kawasaki Throttle Responsive Ignition Control) said ignition system. It provides a function of throttle position and speed by means of adjustment of the optimum ignition timing for an improved throttle response in the lower engine speeds. Furthermore, the ZR -7 was added to a float chamber heater to improve cold start behavior and cold run. Additional built- in engine block cooling by spray nozzles ensure the piston from the bottom with oil. Next, the oil pump was fitted with a larger trochoid. This has been increased from 16 mm to 20 mm around the oil pressure to increase, as the oil nozzles have been added under the piston. The timing chain tensioner was modified, built a chain tensioner on the primary chain and modified tooth flank profiles in the transmission found their way into the ZR- seventh The motor paint changed from silver to black.

And finally, the exhaust system was revised. Thus, a 4 -into-2 - into -1 system from the original 4 -into-2 system.

Your driving is now considered good-natured and makes it therefore also for the beginners easy to control.
