1980 Kawasaki Z 500 Technical Analysis & Specification Breakdown
At the heart of the 1980 Kawasaki Z 500 classic motorcycle, Kawasaki relies on a 498 cc (30.4 cu in) air-cooled in-line four, four-stroke powerplant. In factory specification, peak output is rated at 52 HP (38 kW) at 9,000 rpm while maximum torque reaches 44.1 Nm (32.5 lb-ft) at 7,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 104.4 HP per liter and a 1,500 rpm working window between peak torque (7,500 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 Z 500 measures 210 kg (463 lbs) wet (curb), translating to a power-to-weight ratio of 0.25 HP/kg (4.04 kg per horsepower). The 15-liter (4 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 180 km/h (112 mph).
