At the heart of the 2024 Sym Jet14 Evo 125 Liquid scooter motorcycle, Sym features a 124.6 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 12.5 HP (9.1 kW) at 8,000 rpm while maximum torque reaches 10.3 Nm (7.6 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 100.3 HP per liter and a 2,000 rpm working window between peak torque (6,000 rpm) and peak power (8,000 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
Rider ergonomics and chassis geometry center around a 1,370 mm (53.9 in) wheelbase engineered for quick, flickable steering geometry. The 7.2-liter (1.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
