1977 Laverda 500 Technical Analysis & Specification Breakdown

At the heart of the 1977 Laverda 500 naked motorcycle, Laverda pairs a 496 cc (30.3 cu in) air-cooled twin, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 27 HP (19.7 kW) at 6,850 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 54.4 HP per liter, the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.

On the scales, the 500 measures 189 kg (417 lbs) wet (curb), translating to a power-to-weight ratio of 0.14 HP/kg (7 kg per horsepower). The 13.5-liter (3.6 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 160 km/h (99 mph).
