Built around Motobi's sport motorcycle platform, the 1955 Motobi Catria Lusso relies on a 172 cc (10.5 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 8.5 HP (6.2 kW) at 6,800 rpm, transferring power to the rear wheel through chain final drive. With a specific output of 49.4 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 Catria Lusso measures 97.5 kg (215 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (11.47 kg per horsepower).
