The Kawasaki GPZ 900R, also known as the ZX900A or Ninja 900, was a sports motorcycle manufactured by Kawasaki from 1984 until 2003 when it was replaced by the Kawasaki Ninja ZX-9R.

The bike was the earliest member of the Ninja sports bike family and featured a revolutionary design that soon became the predecessor of modern-day sports motorcycles. It was developed secretly for over six years and was Kawasaki's first 16-valve inline four-cylinder liquid-cooled motorcycle engine.

The bike was fitted with standard features such as a full fairing with parts of the engine left in plain sight, a rectangular headlight, a medium-sized windscreen, a one-piece dual seat with a passenger grab handle, a dual exhaust system with a silencer on each side, and three double-spoke lightweight aluminum wheels.

The bike was built around a double cradle steel frame with a 39 mm telehydraulic air-assisted fork on the front with 140 mm wheel travel and an adjustable shock absorber on the rear with 115 mm wheel travel on the rear.

The braking performance was handled by two 280 mm discs with a single-piston caliper on the front wheel and a 270 mm disc with a single-piston caliper on the rear wheel, offering optimum stopping power.

As for the power figures, the 1984 Kawasaki GPZ 900R Ninja had its soul brought to life by a 908cc four-stroke four-cylinder liquid-cooled engine fed by four carburetors, boasting 108 hp at 9,500 rpm and 85 Nm (63 lb-ft) torque at 8,500 rpm.
