Engineered by BamX for the atv motorcycle segment, the 2010 BamX BX150-S Charger utilizes a 148 cc (9 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 7 HP (5.1 kW) while maximum torque reaches 8.3 Nm (6.1 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 47.3 HP per liter, the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the BX150-S Charger measures 116.1 kg (256 lbs) dry, translating to a power-to-weight ratio of 0.06 HP/kg (16.59 kg per horsepower). Rider ergonomics and chassis geometry center around a 737 mm (29 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,016 mm (40 in) wheelbase engineered for quick, flickable steering geometry.
