Positioned in BamX's atv motorcycle lineup, the 2010 BamX BX70-S Charger pairs a 72 cc (4.4 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 3.2 HP (2.3 kW) while maximum torque reaches 4.2 Nm (3.1 lb-ft) at 5,500 rpm, transferring power to the rear wheel through a automatic gearbox and chain final drive. With a specific output of 44.4 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 BX70-S Charger measures 111.1 kg (245 lbs) dry. Rider ergonomics and chassis geometry center around a 686 mm (27 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. The 10-liter (2.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
