At the heart of the 1955 Ardie BZ 350 sport motorcycle, Ardie relies on a 342 cc (20.9 cu in) air-cooled twin, two-stroke powerplant. In factory specification, peak output is rated at 20 HP (14.6 kW) at 5,000 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. With a specific output of 58.5 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 BZ 350 measures 161 kg (355 lbs) dry, translating to a power-to-weight ratio of 0.12 HP/kg (8.05 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 125 km/h (78 mph).
