2019 Sym NHT 125 Technical Analysis & Specification Breakdown

At the heart of the 2019 Sym NHT 125 naked motorcycle, Sym features a 124.1 cc (7.6 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 10.1 HP (7.3 kW) at 8,500 rpm while maximum torque reaches 9.5 Nm (7 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 81.4 HP per liter and a 2,000 rpm working window between peak torque (6,500 rpm) and peak power (8,500 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.

Rider ergonomics and chassis geometry center around a 1,405 mm (55.3 in) wheelbase engineered for quick, flickable steering geometry. The 11-liter (2.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
