Engineered by Sym for the scooter motorcycle segment, the 2019 Sym Cruisym 300 pairs a 278.3 cc (17 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 27.5 HP (20.1 kW) at 7,750 rpm while maximum torque reaches 27 Nm (19.9 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 98.8 HP per liter and a 1,000 rpm working window between peak torque (6,750 rpm) and peak power (7,750 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 300 measures 198 kg (437 lbs) wet (curb), translating to a power-to-weight ratio of 0.14 HP/kg (7.2 kg per horsepower). Rider ergonomics and chassis geometry center around a 760 mm (29.9 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 supports practical everyday commuting and weekend road stints, while factory top speed is listed at 129 km/h (80 mph).
