Engineered by Benelli for the scooter motorcycle segment, the 2015 Benelli ZenZero 350 features a 313 cc (19.1 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 21 HP (15.3 kW) at 7,000 rpm while maximum torque reaches 23.7 Nm (17.5 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 67.1 HP per liter and a 1,000 rpm working window between peak torque (6,000 rpm) and peak power (7,000 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the ZenZero 350 measures 180 kg (397 lbs) wet (curb), translating to a power-to-weight ratio of 0.12 HP/kg (8.57 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,545 mm (60.8 in) wheelbase engineered for planted straight-line stability. The 13.5-liter (3.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
