Engineered by Xmotos for the enduro - offroad motorcycle segment, the 2008 Xmotos XB-31 utilizes a 150 cc (9.2 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 12.5 HP (9.1 kW), transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 83.3 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the XB-31 measures 96.5 kg (213 lbs) dry, translating to a power-to-weight ratio of 0.13 HP/kg (7.72 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,340 mm (52.8 in) wheelbase engineered for quick, flickable steering geometry. The 3-liter (0.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
