Built around Beta's scooter motorcycle platform, the 2006 Beta Ark 50 pairs a 49 cc (3 cu in) liquid-cooled single cylinder, two-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 40.0 x 39.7 mm (1.6 x 1.6 inches) with a 12.0:1 compression ratio.
On the scales, the Ark 50 measures 88 kg (194 lbs) dry. Rider ergonomics and chassis geometry center around a 1,240 mm (48.8 in) wheelbase engineered for quick, flickable steering geometry. The 7.5-liter (2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
