2008 Vento Phantom LI Technical Analysis & Specification Breakdown
Positioned in Vento's scooter motorcycle lineup, the 2008 Vento Phantom LI relies on a 150 cc (9.2 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 9.4 HP (6.9 kW) at 7,600 rpm while maximum torque reaches 8.5 Nm (6.3 lb-ft) at 5,100 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 62.7 HP per liter and a 2,500 rpm working window between peak torque (5,100 rpm) and peak power (7,600 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 Phantom LI measures 103.9 kg (229 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (11.05 kg per horsepower). Rider ergonomics and chassis geometry center around a 884 mm (34.8 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control. The 5.29-liter (1.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
