Kawasaki first introduced the GPz1000RX sport bike in 1985 for the 1986 model year. This bike, known in North America as the "Ninja 1000R," used the largest-displacement engine that Kawasaki had installed in the Ninja class at that time. Like other models in the GPZ sport lineup, the 1000R featured a full fairing.
Kawasaki outfitted the Ninja 1000R with a transverse mounted, 997 cc, four-stroke, in-line four cylinder engine. This engine utilized a carburetor and a dual overhead cam (DOHC) configuration with four valves per cylinder. Each cylinder got its charge from a single spark plug. The engine's bore measured 2.91 inches and its stroke measured 2.28 inches.
The 1000R's wet sump system used 10W/40 oil to lubricate the engine. The engine had Kawasaki's TCI, or transistor-controlled, ignition.
Kawasaki equipped the 1000R with a wet clutch and a six-speed manual transmission that transferred power to the rear wheels via a chain drive.
The Ninja 1000R's engine cranked out 125 horsepower at 9,500 rpm and 66.4 foot-pounds of torque at 7,000 rpm. The engine had a compression ratio of 10.2 to 1.
The Ninja 1000R could accelerate from 0 to 60 mph in 3.2 seconds and could pass the quarter mile mark in 10.7 seconds with a speed of 128.5 mph.Top speed was 143 mph.
The seat of the 1986 Ninja 1000R sat 31.1 inches above the curb. This bike's wheel base spanned 59.3 inches. It had a dry weight of 533 lb. When fully oiled and with a full tank of gas in its 5.5-gallon fuel tank, the 1986 Ninja 1000R weighed 588 lb.
Kawasaki fitted both the front and rear wheels with disc brakes. The front wheels took a pair of 280 mm discs that used Two-piston calipers and the back wheels sported a single disc that had a diameter of 260 mm. This bike rode on a 120/80-16 front tire and a 150/80-16 rear tire.
