In 1997, the Japanese motorcycle manufacturer launched the Kawasaki EX 500R Ninja (GPZ 500S), a sports motorcycle manufactured by Kawasaki from 1987 until 2009, when it was replaced by the Ninja 650R.
Before 1997, the bike received a major revision in 1994, with changes including larger 17-inch wheels with wider tires, a redesigned front and rear fairing, a redesigned instrument cluster and dials, a new brake disc that replaced the drum unit previously used, and a firmer suspension system.
Also, the bike received several improvements to the engine, such as a revised alternator for better reliability. In addition, the Cam Chain Tensioner (CCT), flywheel, and transmission were easily installable with minimal modifications to fit any first-generation model made between 1987 and 1993.
In the aesthetic department, the bike had fitted standard features, such as a bikini fairing with a lower engine fairing, a rectangular headlight, a small windscreen, a one-piece dual seat with a passenger grab handle, a dual exhaust system, and three-spoke lightweight aluminum wheels.
The bike was built on a double cradle steel frame with a 36 mm Kayaba telescopic fork on the front and a single Kayaba shock absorber on the rear, delivering optimum suspension performance and handling.
As for the power figures, the 1997 Kawasaki EX 500R Ninja (GPZ 500S) had its soul brought to life by a 498cc four-stroke parallel-twin liquid-cooled engine that delivered an output power of 60 hp at 9,800 rpm and 46 Nm (34 lb-ft) torque at 8,500 rpm.
