Engineered by Kawasaki for the sport touring motorcycle segment, the 1983 Kawasaki GPZ 1100 features a 1089 cc (66.5 cu in) air-cooled in-line four, four-stroke configuration. In factory specification, peak output is rated at 120 HP (87.6 kW) at 9,000 rpm while maximum torque reaches 100.3 Nm (74 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 110.2 HP per liter and a 2,000 rpm working window between peak torque (7,000 rpm) and peak power (9,000 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
On the scales, the GPZ 1100 measures 266 kg (586 lbs) wet (curb), translating to a power-to-weight ratio of 0.45 HP/kg (2.22 kg per horsepower). The 20-liter (5.3 US gal) fuel tank supports practical everyday commuting and weekend road stints.
