Kawasaki GPZ400R (1985-1988)

The Kawasaki GPZ 400R sports bike model appeared in 1985 as a domestic Japanese version of the Kawasaki GPZ 600R (Ninja 600R). Unlike the export prototype, the GPZ400R received an aluminum frame from the outset, called the Al-X Cross Frame. The export version was equipped with this frame only in the modification Kawasaki Ninja 600RX, offered only in 1987 for the American market.

At the time of its release, the Kawasaki GPZ 400 R model was in great demand - in the first year it sold 18,200 motorcycles. This success was due to the then motorcycle "boom" and the rapid fashion for replica sports motorcycles. By the way, the export version Kawasaki GPZ 600R (Ninja 600R) was distinguished by record power characteristics and also gained popularity in foreign markets.

In 1987, the company released the successor to the GPZ400R model, which became GPX400R (by analogy with the export version - Kawasaki GPX600R), however, the GPZ 400 existed on the market until 1989.

By 1990, the GPZ400 and GPX400 were leaving the market, giving way to a new model - Kawasaki ZZ-R400.

The main feature of the Kawasaki GPZ400R is a liquid-cooled, in-line 4-cylinder 398 cc engine producing 59 hp. power and 35 Nm of torque. The motor is high-speed, the maximum performance is 10,000-12,000 rpm. The maximum speed is 205 km / h.

Other features of the model include an aluminum tubular frame, front suspension with anti-sip function, narrow wheels 16 ', disc 1-piston brakes (in 1989 - 2-piston), 6-speed gearbox, fuel tank of 18 liters and 176 kg dry matter (1989 version - 181 kg).
