2022 Sym Maxsym 400 Technical Analysis & Specification Breakdown

At the heart of the 2022 Sym Maxsym 400 custom - cruiser motorcycle, Sym relies on a 399 cc (24.4 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 33.5 HP (24.5 kW) at 6,750 rpm while maximum torque reaches 39.5 Nm (29.1 lb-ft) at 5,250 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 84 HP per liter and a 1,500 rpm working window between peak torque (5,250 rpm) and peak power (6,750 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 215 kg (474 lbs) wet (curb), translating to a power-to-weight ratio of 0.16 HP/kg (6.42 kg per horsepower). Rider ergonomics and chassis geometry center around a 800 mm (31.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,555 mm (61.2 in) wheelbase engineered for planted straight-line stability. The 13-liter (3.4 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 139 km/h (86 mph).
