At the heart of the 2017 Vento Proton 150 allround motorcycle, Vento pairs a 149 cc (9.1 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 11 HP (8 kW), transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 73.8 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 Proton 150 measures 97 kg (214 lbs) wet (curb), translating to a power-to-weight ratio of 0.11 HP/kg (8.82 kg per horsepower). Rider ergonomics and chassis geometry center around a 760 mm (29.9 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops. The 10-liter (2.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
