Positioned in WT Motors's atv motorcycle lineup, the 2011 WT Motors Siberian WT625 i.e. relies on a 493 cc (30.1 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 19.4 HP (14.2 kW) at 6,000 rpm while maximum torque reaches 28.5 Nm (21 lb-ft) at 4,750 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 39.4 HP per liter and a 1,250 rpm working window between peak torque (4,750 rpm) and peak power (6,000 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the Siberian WT625 i.e. measures 344 kg (758 lbs) dry, translating to a power-to-weight ratio of 0.06 HP/kg (17.73 kg per horsepower). Rider ergonomics and chassis geometry center around a 550 mm (21.7 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with 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.
