Built around Vento's naked motorcycle platform, the 2017 Vento Lucky 7 400 relies on a 400 cc (24.4 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 27 HP (19.7 kW), transferring power to the rear wheel through chain final drive. With a specific output of 67.5 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 Lucky 7 400 measures 143 kg (315 lbs) wet (curb), translating to a power-to-weight ratio of 0.19 HP/kg (5.3 kg per horsepower). Rider ergonomics and chassis geometry center around a 790 mm (31.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance. The 13-liter (3.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
