Engineered by Sym for the custom - cruiser motorcycle segment, the 2019 Sym Maxsym 400 features a 399 cc (24.4 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 35 HP (25.5 kW) at 7,000 rpm while maximum torque reaches 34.5 Nm (25.4 lb-ft) at 5,500 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 87.7 HP per liter and a 1,500 rpm working window between peak torque (5,500 rpm) and peak power (7,000 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the Maxsym 400 measures 229 kg (505 lbs) dry, translating to a power-to-weight ratio of 0.15 HP/kg (6.54 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 1,570 mm (61.8 in) wheelbase engineered for planted straight-line stability. The 14.7-liter (3.9 US gal) fuel tank paired with a rated consumption of 4 L/100 km provides an estimated theoretical range of roughly 368 km (229 miles) between fill-ups, while factory top speed is listed at 143 km/h (89 mph).
