At the heart of the 2023 Sym Cruisym Alpha 125 scooter motorcycle, Sym pairs a 124.9 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 14.1 HP (10.3 kW) at 8,750 rpm while maximum torque reaches 11.3 Nm (8.3 lb-ft) at 6,750 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 112.9 HP per liter and a 2,000 rpm working window between peak torque (6,750 rpm) and peak power (8,750 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
On the scales, the Cruisym Alpha 125 measures 179 kg (395 lbs) wet (curb), translating to a power-to-weight ratio of 0.08 HP/kg (12.7 kg per horsepower). Rider ergonomics and chassis geometry center around a 750 mm (29.5 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,550 mm (61 in) wheelbase engineered for planted straight-line stability. The 12-liter (3.2 US gal) fuel tank paired with a rated consumption of 2.13 L/100 km provides an estimated theoretical range of roughly 563 km (350 miles) between fill-ups, while factory top speed is listed at 99 km/h (62 mph).
