2020 Sym JoyMax Z 300 Technical Analysis & Specification Breakdown
At the heart of the 2020 Sym JoyMax Z 300 scooter motorcycle, Sym features a 278 cc (17 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 27 HP (19.7 kW) at 8,000 rpm while maximum torque reaches 27.3 Nm (20.1 lb-ft) at 8,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 97.1 HP per liter, 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 300 measures 184 kg (406 lbs) dry, translating to a power-to-weight ratio of 0.15 HP/kg (6.81 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 paired with a rated consumption of 2.5 L/100 km provides an estimated theoretical range of roughly 480 km (298 miles) between fill-ups, while factory top speed is listed at 128 km/h (80 mph).
