At the heart of the 2017 Linhai Aeolus Retro 150 scooter motorcycle, Linhai features a 147.5 cc (9 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 8.7 HP (6.4 kW) at 7,500 rpm while maximum torque reaches 8 Nm (5.9 lb-ft) at 4,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 59 HP per liter and a 3,500 rpm working window between peak torque (4,000 rpm) and peak power (7,500 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the Aeolus Retro 150 measures 135.2 kg (298 lbs) dry, translating to a power-to-weight ratio of 0.06 HP/kg (15.54 kg per horsepower). Rider ergonomics and chassis geometry center around a 709 mm (27.9 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,501 mm (59.1 in) wheelbase engineered for balanced agility and highway composure. The 9.46-liter (2.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
