In 1987, the Japanese motorcycle manufacturer launched the Kawasaki GPZ 900R Ninja, a sports motorcycle that debuted in 1984 and continued production until 2003, when it was replaced by the Ninja ZX-9R.

At its release in 1984, the bike was the earliest member of the Ninja family of sports machines. It featured a revolutionary design immediately, making it the predecessor of modern-day sports motorcycles.

Despite its performance, the Kawasaki GPZ 900R was smooth and reliable in urban traffic due to its new suspension system and crankshaft counter-balancer that reduced almost entirely secondary vibrations.

The 1987 motorcycle was fitted with standard features, such as a half-fairing with a rectangular headlight, a medium-sized windscreen, a one-piece dual seat with a pillion grab handle, a dual exhaust system with a silencer on each side, and lightweight aluminum wheels.

The bike was built around a diamond steel frame with a 39 mm telehydraulic telescopic adjustable fork on the front with 140 mm wheel travel and an adjustable shock absorber on the rear with 115 mm wheel travel.

As for the power figures, the 1987 Kawasaki GPZ 900R Ninja had installed underneath its fuel tank a 908cc four-stroke four-cylinder liquid-cooled engine managed by four Keihin carburetors, delivering 108 hp at 9,500 rpm and 85 Nm (63 lb-ft) torque at 8,500 rpm.
