Built around Serpento's allround motorcycle platform, the 2020 Serpento Aspid 150 features a 149.6 cc (9.1 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 12 HP (8.8 kW) at 8,000 rpm while maximum torque reaches 9.8 Nm (7.2 lb-ft), transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 80.2 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the Aspid 150 measures 109 kg (240 lbs) dry, translating to a power-to-weight ratio of 0.11 HP/kg (9.08 kg per horsepower). Rider ergonomics and chassis geometry center around a 870 mm (34.3 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 2,050 mm (80.7 in) wheelbase engineered for planted straight-line stability. The 11-liter (2.9 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 90 km/h (56 mph).
