At the heart of the 2011 BamX BX150-DB Voyager enduro - offroad motorcycle, BamX utilizes a 149 cc (9.1 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 9.5 HP (6.9 kW) while maximum torque reaches 12.5 Nm (9.2 lb-ft) at 5,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 63.8 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 BX150-DB Voyager measures 102.1 kg (225 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (10.75 kg per horsepower). Rider ergonomics and chassis geometry center around a 762 mm (30 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,295 mm (51 in) wheelbase engineered for quick, flickable steering geometry. The 5-liter (1.3 US gal) fuel tank supports practical everyday commuting and weekend road stints.
