Engineered by BamX for the atv motorcycle segment, the 2012 BamX BX50-U Exciter pairs a 49.5 cc (3 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 2 HP (1.5 kW) while maximum torque reaches 2.8 Nm (2.1 lb-ft) at 5,500 rpm, transferring power to the rear wheel through a automatic gearbox and chain final drive. Internal engine geometry specifies a bore and stroke of 39.0 x 41.1 mm (1.5 x 1.6 inches) with a 9.0:1 compression ratio.
On the scales, the BX50-U Exciter measures 79.8 kg (176 lbs) dry. Rider ergonomics and chassis geometry center around a 610 mm (24 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 940 mm (37 in) wheelbase engineered for quick, flickable steering geometry. The 4-liter (1.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
