Built around Sym's scooter motorcycle platform, the 2014 Sym GTS Joymax 125i evo relies on a 124.6 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 13 HP (9.5 kW) at 9,000 rpm while maximum torque reaches 11.1 Nm (8.2 lb-ft) at 7,500 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 104.3 HP per liter and a 1,500 rpm working window between peak torque (7,500 rpm) and peak power (9,000 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 GTS Joymax 125i evo measures 167 kg (368 lbs) dry, translating to a power-to-weight ratio of 0.08 HP/kg (12.85 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,495 mm (58.9 in) wheelbase engineered for balanced agility and highway composure. The 12-liter (3.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
