Engineered by WT Motors for the atv motorcycle segment, the 2011 WT Motors Poseydon WT400 relies on a 401 cc (24.5 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 25.2 HP (18.4 kW) at 6,000 rpm while maximum torque reaches 29 Nm (21.4 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 62.8 HP per liter and a 500 rpm working window between peak torque (5,500 rpm) and peak power (6,000 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 Poseydon WT400 measures 326 kg (719 lbs) dry, translating to a power-to-weight ratio of 0.08 HP/kg (12.94 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,290 mm (50.8 in) wheelbase engineered for quick, flickable steering geometry. The 19-liter (5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
