2017 Linhai St. Marlo 50 Technical Analysis & Specification Breakdown

Built around Linhai's scooter motorcycle platform, the 2017 Linhai St. Marlo 50 relies on a 49 cc (3 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 3 HP (2.2 kW) at 7,500 rpm while maximum torque reaches 3 Nm (2.2 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive.
