2017 Linhai St. Marlo 150 Technical Analysis & Specification Breakdown

Positioned in Linhai's scooter motorcycle lineup, the 2017 Linhai St. Marlo 150 relies on a 149 cc (9.1 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 8.1 HP (5.9 kW) at 7,500 rpm while maximum torque reaches 9.3 Nm (6.9 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 54.4 HP per liter and a 2,000 rpm working window between peak torque (5,500 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 St. Marlo 150 measures 100 kg (220 lbs) dry, translating to a power-to-weight ratio of 0.08 HP/kg (12.35 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,380 mm (54.3 in) wheelbase engineered for quick, flickable steering geometry. The 5.8-liter (1.5 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 85 km/h (53 mph).
