At the heart of the 2017 Linhai Aeolus Mainstreet 300 scooter motorcycle, Linhai relies on a 275 cc (16.8 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 18.7 HP (13.6 kW) at 6,500 rpm while maximum torque reaches 23 Nm (17 lb-ft) at 5,500 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 68 HP per liter and a 1,000 rpm working window between peak torque (5,500 rpm) and peak power (6,500 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 Aeolus Mainstreet 300 measures 167.8 kg (370 lbs) dry, translating to a power-to-weight ratio of 0.11 HP/kg (8.97 kg per horsepower). Rider ergonomics and chassis geometry center around a 739 mm (29.1 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,534 mm (60.4 in) wheelbase engineered for planted straight-line stability. The 12.11-liter (3.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
