Built around Honda's cross - motocross motorcycle platform, the 1987 Honda CR 500 relies on a 495 cc (30.2 cu in) liquid-cooled single cylinder, two-stroke powerplant. In factory specification, peak output is rated at 63 HP (46 kW), transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 127.3 HP per liter, 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 CR 500 measures 102.1 kg (225 lbs) wet (curb), translating to a power-to-weight ratio of 0.62 HP/kg (1.62 kg per horsepower).
