2024 Sym Joymax Z Plus 125 Technical Analysis & Specification Breakdown
Built around Sym's scooter motorcycle platform, the 2024 Sym Joymax Z Plus 125 features a 124.9 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 14.1 HP (10.3 kW) at 8,750 rpm while maximum torque reaches 11.8 Nm (8.7 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 Joymax Z Plus 125 measures 172 kg (379 lbs) wet (curb), translating to a power-to-weight ratio of 0.08 HP/kg (12.2 kg per horsepower). Rider ergonomics and chassis geometry center around a 770 mm (30.3 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,530 mm (60.2 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.
