Engineered by BamX for the minibike, cross motorcycle segment, the 2015 BamX BX150-DB Voyager relies on a 149 cc (9.1 cu in) air-cooled single cylinder, two-stroke powerplant. In factory specification, peak output is rated at 16.1 HP (11.7 kW) at 6,000 rpm 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 108.1 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 reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
On the scales, the BX150-DB Voyager measures 102.1 kg (225 lbs) dry, translating to a power-to-weight ratio of 0.16 HP/kg (6.34 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 18.93-liter (5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
