At the heart of the 2012 Sym XS125-K allround motorcycle, Sym utilizes a 124.1 cc (7.6 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 10.2 HP (7.4 kW) at 8,500 rpm while maximum torque reaches 9 Nm (6.6 lb-ft) at 7,500 rpm, transferring power to the rear wheel through chain final drive. With a specific output of 82.2 HP per liter and a 1,000 rpm working window between peak torque (7,500 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.
On the scales, the XS125-K measures 148 kg (326 lbs) wet (curb), translating to a power-to-weight ratio of 0.07 HP/kg (14.51 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,280 mm (50.4 in) wheelbase engineered for quick, flickable steering geometry. The 16.5-liter (4.4 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 92 km/h (57 mph).
